sdf's gopher space.
Text files need 644 permissions, and directories need 755 permissions.
Entries in a gophermap need an actual tab character between description
and location. I've not sorted if each directory needs its own gophermap
yet, or if you can have one gophermap at root and just list directory
contents.

xfce4 version 4.12 on Slackware 15.0
https://www.linuxquestions.org/questions/slackware-14/this-is-my-slackware-desktop-725754/page355.html#post6537448
'backleveled' to xfce version 4.12 (last GTK2) with selection of
libraries that need adding. Also some compiler errors with newer
compilers but not sure if those are with the xfce.

To stop the screen switching on when you move the phone or touch the
screen you have to:
1) Switch Ambient Display on and disable 'turn on touch screen'
2) Switch Ambient Display off again (rolleyes)
3) Switch Lift to Wake off
Then the screen won't come on until you short press the power button and
sanity is regained.

Reduce computer algebra package installed from the most recent
snapshot rpm. I use the Codemist Standard Lisp implementation.
redcsl invokes a GUI repl by default.
This GUI is implemented using the fox toolkit which is quite nice
light and cross platform BUT the default font sizes are tiny even on
a 1366x768 screen. There is a font size setting for the font used in
the repl but not in the font used in the GUI widgets (menu 'bar'
which is actually buttons and the associated menus).
https://sourceforge.net/p/foxgui/mailman/message/14874756/
The foxgui-users mailing list came up with a work-around.
Add the following to the settings file at
~/.foxrc/Codemist/reduce
[SETTINGS]
normalfont=helvetica,140,medium,roman,normal,iso8859-1
If the Xorg bitmap font you happen to use is not available, the
application will just segfault. I needed to experiment a bit, but
the above worked on Fedora 21 under Gnome/Wayland presumably under
xwayland. So it appears that 'normalfont' provides the base font for
all the widgets.

Cinnamon DE set critical battery action to suspend and change time
Installed Mint LMDE 6 (Faye) on x220.
The critical battery settings did not by default include suspend, so
I added it as follows;
https://forums.linuxmint.com/viewtopic.php?f=42&t=302573&hilit=power#3
edit /usr/share/cinnamon/cinnamon-settings/modules/cs_power.py
as root and alter the 'critical_options' python statement (a fair way down the file) to read
critical_options = [
("shutdown", _("Shutdown immediately")),
("hibernate", _("Hibernate")),
("suspend", _("Suspend")),
("nothing", _("Do nothing"))
]
Basically adding the line '("suspend", _("Suspend")),'. Go to settings
Power Manager and you'd find Suspend as an option.
Then increase the default battery life to trigger critical actions from
420 second to 1800 seconds (7 mins to 30 mins) so you have time to find
a mains plug. 30 mins on normal is about 6 to 8 hours on suspend.
Nice to see a setting from Cinnamon 19 still working.
Documents: make a draft script in ~/bin
Current state of mkdrft
keith@x220:~$ cat ~/bin/mkdrft
#! /bin/sh
# Variables
dir=$PWD/drafts
file="$1"
date=$(date -I)
# Test for drafts directory in current directory
# and it it isnt there create it
if [ ! -e $dir ]; then
mkdir $dir
elif [ ! -d $dir ]; then
echo "$dir already exists but is not a directory"
fi
# Make a copy of $file inside drafts with date added to
# end of file name
cp $file $dir/$file"-"$date
keith@x220:~$
Basic: it allows over writing of drafts with same date. But at least it
catches directory not there or a file of same name. Works fine in test
directory.

https://christian.amsuess.com/tools/arandr/
Just installed arandr to help with external monitors.
xfig has very small bitmap fonts hard coded.
A 1280x1024 large monitor will help.
But also
xrandr --output LVDS-1 --scale 0.8x0.8
and
xrandr --output LVDS-1 --scale 1x1
The first command line zooms in so xfig looks 25% larger which is fine
The second command reverts to 100% scale.

the commands available.

echo "This is a sentence with *two words* emphasised" | sed 's/ \*/ \\fI/' | sed 's/\* /\\fR /'
Ugly but it works. Might allow emphasis to span two lines as well as
separate patterns for start of emphasis (asterisk preceeded by a space)
and for end (asterisk succeeded by a space).
cat bread.ms | sed 's/^$/.PP/' | sed 's/ \*/ \\fI/' | sed 's/\* /\\fR /' | groff -T pdf -ms > b.pdf
If I put the sed lines above into a script file and use them as a
filter, and add sed lines for **strong** and `code` then that is a chunk
of markup already done. Just need to disable the matching inside the
preprocessor requests like .EQ....EN.
So far I have this...
foo$ cat mrk.sh
cat $1 | # useless use of cat?
sed 's/^$/.PP/' | # put paragraph request in each blank line
sed 's/ \*/ \\fI/' | # space-* = start of italics
sed 's/\* /\\fR /' | # *-space = end of italics
sed 's/^\# /.NH 1\
/' # OpenBSD sed won't allow \n in substitution so literal new line
I'll add in the other character styles and the rest of the headings
tommorrow.
Note from the future
echo "This *might* be a *sentence*. And *this*?" \
| sed 's/\([.? ]\)\*/\1\\fI/g' | sed 's/\*\([.? ]\)/\\fR\1/g'
Capture expressions or 'backreferences' (but not actually).
The [.? ] means match either of a full-stop, a question mark or a space.
The \([.? ]\) 'captures' this match as \1 (you can have up to \9 of these)
The replacement part prints what you captured as \1 and what you want to replace it with
It is the second sed that is important...
sed 's/\*\([.? ]\)/\\fR\1/g'
's/matched expression/substitution/g'
The matched expression is \* (an asterisk) and [.? ] any of . or ? or a space.
The \(part\) bit of the matched expression is stored as \1
The g on the end says not to stop after first match on a line.
The substitution is \\fR first (need \\ because we want a literal \ printed)
then whatever we stored in the substitution \1 gets printed
So: thing*. -> thing/fR.
And that*? -> that/fR?
And something* else -> something/fR else
Problem: how do I include punctuation in the emphasis?
Cross that bridge &c

awk '
NF { printf sep "%s", $0; sep = ""; next }
{ sep = "\n\n" }
END { printf "\n" }
' filename
Above fragment takes a text file with paragraphs with hard breaks
(single new line) at the end of each line and a blank line between
paragraphs and renders it as a single line for each paragraph but
preserves the blank line between paragraphs. Exactly what I want for the
markdownish -> ms converter that I want to hack up.
Then blank line -> .PP
Line starting with * after a blank line but with space following * -> .IP "\[bu]" 0.25i
Word in a line starting with * like *emphasis -> \fI
Word in a line ending with * like emphasis* -> \fR
And **strong -> \fB with strong** -> \fR
And `words -> \fC with words` -> \fR
Above will need to trap no space after * | ** | ` to avoid list at line start
Line starting with # words -> .NH 1 \n words \n .LP supressing .PP
Line starting with ## words - .NH 2 \n words \n .LP supressing .PP
Line starting with ### words - .NH 3 \n words \n .LP supressing .PP
And then
Line starting with .EQ | .TS | .PS | .RS | .G1 -> pass all lines through verbatim until
Line starting with .EN | .TE | .PE | .RE | .G2 -> lines after processed as normal
This is not a markdown to -> ms converter as such it is just saving time
and allowing drafting of text before doing the markup.
For added points, once substitutions made, each line broken into hard
break lines again in one sentence per line mode while preserving the
troff code.

The ftp function on OpenBSD has more functionality than the one
in Linux. It can fetch Web pages. So below is a preliminary mad
science hack that can fetch a Web page, get rid of one level
of html tags, dump the resulting textish stuff into format and then
into less with 'squash lines'.
ftp -o -
https://www.theregister.com | sed -e 's/<[^>]*>//g' | fmt | less -s
Sort of works, but misses style sheets and scripts so a couple
more sed lines needed for {css} and <script> and stuff.
Has legs. Mad science idea: OpenBSD base comes with mandoc which
can format to pdf, html, ps and so on out of the box. Can also
format to plain text.

nvi on Slackware 15 segfaults if you try to use the cedit option to make

suggests a work around
Recompile nvi. Configure as normal.
At the make stage, pass a variable as follows
OPTFLAG="$SLKCFLAGS" make
some fiddling with the slackbuild might be needed. Works fine on Debian.
Above does not work
https://github.com/johnsonjh/OpenVi
Removed the nvi package and compiled OpenVI (alas no UTF-8).
As per instructions
* unzip the git file somewhere
* cd OpenVi-master
* make
* make install
Me being a lasy person, the default compile goes into
/usr/local/bin/ovi
and the manual pages get put in /usr/local/share/man/
which is not on manpath
So I just simlinked
ln -s /usr/local/share/man/man1/ovi.1 /usr/man/man1/vi.1
ln -s /usr/local/share/man/man1/oview.1 /usr/man/man1/view.1
ln -s /usr/local/share/man/man1/oex.1 /usr/man/man1/ex.1
ln -s /usr/local/share/man/man8/ovi.recover.8 /usr/man/man8/vi.recover.8
and I simlinked the binary to vi as follows
ln -s /usr/local/bin/ovi /usr/bin/vi
ln -s /usr/local/bin/oview /usr/bin/view
ln -s /usr/local/bin/oex /usr/bin/ex
When you remove the nvi package it simlinks vi to vim
so I had to delete those simlinks first.

Terminus bitmap font on OpenBSD 7.5 so I can use xterm with nice sharp
characters.
foo$ pkg_info -Q terminus
terminus-font-4.49.1p1 (installed)
terminus-font-4.49.1p1-centered_tilde
terminus-font-4.49.1p1-symquotes
terminus-font-4.49.1p1-symquotes-centered_tilde
terminus-nerd-fonts-3.0.2
I went for the plain terminus font as you can see that is the one that
is installed. Build a list of the fonts in the directory...
# cd /usr/local/share/fonts/terminus
# mkfontdir
Temporary Xorg font path can be set with xset (e.g. in .xsession)
$ xset fp+ /usr/local/share/fonts/terminus
Then use xfontsel to find the 'terminus' family and try out various
sizes. On the X201's screen I found the 24 pixel size to be best as
default...
-*-terminus-medium-*-*-*-24-*-*-*-*-*-iso8859-1
So I added the following into .Xdefaults
foo$ cat .Xdefaults
! $OpenBSD: dot.Xdefaults,v 1.3 2014/07/10 10:22:59 jasper Exp $
XTerm*loginShell:true
xterm*font5: -*-terminus-medium-*-*-*-28-*-*-*-*-*-iso8859-1
xterm*font: -*-terminus-medium-*-*-*-24-*-*-*-*-*-iso8859-1
foo$
The font5 size is the 'large' font in the xterm menu.
Below is the rest of the basic .Xdefaults (still need the xft stuff)
foo$ cat .Xdefaults

OpenBSD: installed xfce and all fine on the guest wifi in the

Had to manually delete /var/db/pkg/partial* entries (these are
directories) as pkg_check had checked them and suggested they were not a
problem because partial but pkg_delete could not delete them.
Having done that, I was able to install pythons and ghostscript and the

Suggests using
wpa_supplicant_flags="-B -i wpi0 -D bsd -c /etc/wpa_supplicant.conf"
in rc.conf to get around the firmware error messages and sporadic wifi

Also NetBSD does cpu frequency control from userspace so install `estd`.

Convert eps or pdf to svg
svg files import into OpenOffice and LibreOffice well. troff based
preprocessors can produce .ps or .pdf files well. So investigate the use
of a converter.
https://superuser.com/questions/198460/converting-from-eps-to-svg-format
pdf2svg is in slackbuilds and has no dependencies. Suggested conversion
commands are:
ps2pdf -dEPSCrop infile.eps
pdf2svg infile.pdf outfile.svg
Or later in thread...
epspdf infile.eps
pdf2svg infile.pdf outfile.svg
Remember that ps2pdf is basically Adobe Distiller for Linux.

Hilarious fun with my newly aquired external usb webcam on its gooseneck stand

https://serverfault.com/questions/54949/how-can-i-use-rsync-with-a-fat-file-system
Sorting out using an rsync command line to sync my T60 folder with a USB
stick with FAT format. Used to have problems with it copying all the
files every time, even the unchanged ones. Using the --size-only option
seems to sort that one (FAT records file modification time with limited
accuracy).
# Backup Documents folder to T42DOCS/T60 which is FAT format
alias r-back="rsync --progress \
--size-only \
--update \
--recursive ~/Documents /run/media/keith/T42DOCS/T60/"
The plan: I've disabled the radios in BIOS on the T60 so the only way
you connect this machine to the Web is using the yellow ethernet cable
to the router downstairs. Once a day for backup is the plan...

# echo 90 > /sys/class/backlight/intel_backlight/brightness
On the X250 the brightness keys don't work in fluxbox and xbacklight

90 is pretty dim but not dimest, and 852 is value at highest brightness
setting (bright enough to light a film scene).

Grap for groff. Preprocessor for the pic preprocessor for troff.
Produces data plots and (by computing coordinates) plots functions.
Slackbuild from 12.1 does not work as compilers changed.
The grap-master.zip can be unzipped, and then
$ cd grap-master
$ aclocal && autoheader && automake --add-missing && autoconf
Warnings about some missing stuff
$ make
Compiles as user ok. Then as root...
# make install
Puts the man pages in correct places in all.
As user, copy examples back to a suitable directory in your home
$ cp /usr/local/share/examples/grap/* ~/Documents/troff/grap/
bash-5.1$ grog example.ms
groff -T ps -e -G -ms example.ms
So use
groff -T ps -e -G -ms example.ms > eg.ps
as a starting point. All the examples compile OK so the warnings at
configure were probably just the effect of version changes and the
compiler.
January 12th 2024
-----------------
The command below...
ps2pdf -dMaxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true -dPDFSETTINGS=/printer formula.ps
embeds a subset of the fonts in the formula.ps file into a formula.pdf
file in such a way that evince/atril/and all pdf viewers are happy with
especially the maths fonts with the expanding brackets and square root
signs. The file sizes are reasonable. If I use the -P -e option as an
argument to -Tpdf I get the whole font embedded and the file size is
huge. See below...
groff -e -ms -Tpdf -P -e test.ms > test.pdf
So my workflow now is something like
groff -e -ms -Tps formula.ms > formula.ps
Then the big ps2pdf command above to generate the pdf.
Just using default setting results in missing bracket segments for
expanding brackets and in mis-aligned square root signs. But this ONLY
happens on Slackware. Mint linux with Atril &c works fine. Xpdf works
fine on both systems. Everything works fine on Slackware 14.2. I'm
guessing this has something to do with the font paths that Atril and all
try to use.
This is all with groff 1.24.x

Recycled Thinkpad X250 off ebay for 100 notes. Very nice once you get
past the chicklet keyboard (which is solid and has some reasonable key
travel).
This model has an internal (cased) 'bridging battery' which is a cause
of concern. By booting off a live Mint linux stick with the 3-cell
external battery removed on battery power, running a upower command told
me the following...
mint@mint:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
native-path: BAT0
vendor: LGC
model: 45N1113
serial: 2193

charge-cycles: N/A
time to empty: 3.7 hours
percentage: 96%
capacity: 91.9506%
technology: lithium-ion
icon-name: 'battery-full-symbolic'
So the (cased and socketed) internal battery still holds 21.59/23.58
*100 % = 91.5% of its new power. OK for now. Spares are currently still
available for £25 or so off ebay.
With the tiny 3 cell external battery in addition to the internal
battery power manager claims around 7 hours of battery. Lid close
suspend just works as well.
The external battery shows...
mint@mint:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT1
native-path: BAT1
vendor: LGC
model: 45N1127
serial: 9200

voltage: 12.652 V
charge-cycles: N/A
percentage: 100%
capacity: 84.2845%
technology: lithium-ion
icon-name: 'battery-full-charged-symbolic'
History (charge):
1703786158 100.000 fully-charged
So 19.79 / 23.48 * 100 = 84% of original. Shows more wear so may
replace.

## Squeeze on T42 project: loop mount an iso image so apt-get recognises it
<
https://forums.debian.net/viewtopic.php?t=1325>
Text by 'Harold' below (from 2005)
PS Squeeze goes like rocket fuel on the T42
I downloaded
http://cdimage.debian.org/debian-cd/3.1 ... nary-1.iso into /usr/src.
I made two new directories on my hard drive:
# mkdir /iso_image/
# mkdir -p /media/debian/
I mounted the iso image, saved its contents, then unmounted it.
# mount -t iso9660 -o ro,loop /usr/src/debian-31r0a-i386-binary-1.iso /iso_image
# cp /iso_image/* -R /media/debian/
# umount /iso_image
I backed up /etc/apt/sources.list, rem'ed all existing lines and added the following line:
deb file:/media/debian/ stable main contrib
Finally, I opened dselect and updated the Debian package list.
dselect recognized /media/debian as a valid local Debian package repository. :-)
Top
## Later answer without having to copy the files from iso
Try this
mkdir /media/mountpoint
mount -t iso9660 -o loop /pathtoiso.iso /media/mountpoint
then add
deb file:///media/mountpoint distro main contrib
to /etc/sources.list with text editor and not with some GUI tool, then
update from package manager.

map #4 !}fmt^M
map #5 !}ospl^M
The opsl script in my ~/bin folder looks like this...
keith@T60m:~$ cat ~/bin/ospl
# This command breaks a paragraph with hard line breaks
# into one clause per line (sentence, comma or question mark)
# It reverses the effect of fmt
# Meant for use with }!ospl from nvi
tr '\n' ' ' | sed "s/[.,?][ ]*/\0\n/g"
Remember that the ^M in .exrc means Ctrl-V Ctrl-M (escaped new line)
The two complimentary commands are bound to F4 and F5 respectively.
One Sentence Per Line script
----------------------------
$ sed "s/[.,?][ ]*/\0\n/g" <<< "This is, for example, another sentence. And I'm using double space, after the fullstop. Why not? Indeed?"
The sed expression above will insert a new line after any commas, full stops or question marks in a sentence. So the snippet converts from filled paragraphs back to one clause per line. Undoes fmt.
The [.,?] bracket contains the list of punctuation marks to break on.
The [ ]* bit says to match one or more spaces after the punctuation mark.
In the substitution term, the \0 prints the first match in the replacement text.
Turn this into a script.
<
https://unix.stackexchange.com/a/708540>
cat file | tr '\n' ' ' | sed "s/[.,?][ ]/\0\n/g"
Above works for one paragraph with hard line breaks as produced by fmt.
The tr term removes the hard line breaks and replaces with a space so the
paragraphs are all one line long separated by a blank line.
The sed term then does its stuff correctly.
Need to turn this command into a script.

perhaps packages out of sync with the main system. Netsurf and links
fine. Wifi uses iwi0 driver. Needs an acceptance of eula in sysctl.conf
otherwise xconsole prints warnings every second. S3 suspend does not
work, just reboots. May need kernel options and rebuild.
Notes below found from various sources.

use the correct pkgin mirror.
Copy init scripts for everybody's fave
--------------------------------------
# cp /usr/pkg/share/examples/rc.d/dbus /etc/rc.d/
Add these to /etc/rc.conf with the following:
rpcbind=YES
dbus=YES
Microcode (wifi?)
-----------------
# pkgin install intel-microcode-netbsd
copy the start-up script to /etc/rc.d
# cp /usr/pkg/share/examples/rc.d/intel-microcode /etc/
rc.d/
add
microcode=YES
to your rc.conf and reboot
Add non-root user
-----------------
# useradd -g wheel -G users -s /bin/ksh -c "your real
name" -m user_name
# passwd user_name

WiFi
----
iwn0 is the appropriate driver - not sure if installed
as part of core.
https://www.unitedbsd.com/d/672-question-about-netbsd-
wireless-and-wpa-supplicant/24
Edit /etc/rc.conf to include
dhcpcd=YES
dhcpcd_flags="${dhcpcd_flags} -b" (don't wait on boot)
wpa_supplicant=YES
wpa_supplicant_flags=
"-i iwn0 -c /etc/wpa_supplicant.conf"
Then create and edit /etc/wpa_supplicant.conf as usual...
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="myssid"
psk="mypassword"
}
For iwi0 driver the firmware is provided on the install image but you
have to add a line to /etc/sysctl to 'accept' the EULA...
# Accept EULA for iwi0 wifi interface
hw.iwi.accept_eula=1
Will need to see if the wpa_supplicant GUI is available
and does not bring in qt. Restart method...

Idea: download DVD-1 and DVD-2 of Squeeze and build my own little empire

Seamonkey/Firefox not being recent enough to get round the TLS upgrades.

xwd is the screen grap program that is part of x11. Imagemagick convert
is needed because xwd files are bitmaps - no compression - and few
graphics programs can read them. GNU Imp can convert xwd files as well.

Installing extra fonts in OpenBSD 7.3
Higari and Indian language fonts: install noto-cjk and lohit-fonts
packages from ports. The install script runs the font cache. Firefox
picks them up straight away so no more funny boxes on pages.
Apache fonts to deal with OpenOffice docs: manual install of Tinos,
Arimo and OpenSans fonts from Ascender fonts. I used fontsquirrel.
https://www.fontsquirrel.com/fonts/list/foundry/ascender-fonts
Unzip in Downloads, you get the .ttf files
Copy to /usr/X11R6/lib/X11/fonts/TTF/
Run
/usr/X11R6/bin/fc-cache -v
Restart LibreOffice and Writer picks up Tinos, Arimo and OpenSans when a
document written in OpenOffice is opened.

Text to pdf using a cups filter. Command below processes file thing into

/usr/lib/cups/filter/texttopdf 1 1 1 1 1 thing > thing.pdf
From
https://lists.debian.org/debian-user/2023/03/msg00292.html
The 1 1 1 1 1 stuff is just putting dummy values into the arguments to
the cups filter. Just run without arguments to see the options. Not
utf-8 and probably letter paper size nominal.
bash-4.3$ /usr/lib/cups/filter/texttopdf
Usage: texttopdf job-id user title copies options [file]
Might wrap a function around this to use a less long command.
CHARSET=utf-8 /usr/lib/cups/filter/texttopdf 1 1 1 1 1 UTF-8-demo.txt >out.pdf
Above gets round utf-8 from

Debian 11 and TeXmacs
=====================
1) No package in repos
2) Advice is to download the static build from texmacs web site and unpack
3) Because static needs to find libaries so if unpacking in /opt need to
add paths to /etc/profile...
keith@L440:~$ cat /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "$(id -u)" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
export TEXMACS_PATH=/opt/TeXmacs-2.1.1-x86_64-pc-linux-gnu/TeXmacs
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:$TEXMACS_PATH/bin"
fi
export PATH
4) Then added a texmacs.desktop file at ~/.local/share/applications
keith@L440:~$ cat .local/share/applications/texmacs.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false

Name=TeXmacs
Icon=/home/keith/.icons/texmacs-icon.png
The icon was pinched from some github and looks more in keeping with
Gnome Shell than the official xpm files.
The %f bit in the Exec path is the feature that means you can right
click on a .tm file and select TeXmacs as the application to Open
With... in nautilus file manager.

Fedora 37 (Gnome 44.3)
https://discussion.fedoraproject.org/t/touchpad-dont-work-after-suspended/73733/22
1) On waking after a suspend, trackpoint/trackpad frozen. Rest of GUI fine
2) This happens on wayland or Xorg
3) Turns out the trackpad kernel module gets unloaded somehow
4) you have to run this...
sudo modprobe -r -v rmi_smbus && sudo modprobe -v rmi_smbus
[keith@~]$ sudo modprobe -r -v rmi_smbus && sudo modprobe -v rmi_smbus
[sudo] password for keith:

rmmod rmi_core

insmod /lib/modules/6.1.18-200.fc37.x86_64/kernel/drivers/input/rmi4/rmi_smbus.ko.xz
Can't make this up. With Gnome GUI only way to be able to enter the
command is to find a USB mouse and plug it in unless you write the
incantation down and copy it into a terminal.
Debian 11 has a fix (actually Ubuntu board)

mg and backspace delete
=======================
Add following to .Xresources...
xterm.*backarrowKey: false
Add following to .emacs...
(if (not window-system) (normal-erase-is-backspace-mode 0))
Then emacs works as you'd expect and mg compiled from the slackbuild
also does backspace delete.
Meta key in `Xterm` is a problem with `mg` so try...
/home/keith$ cat .inputrc
set meta-flag on
set convert-meta off
set output-meta on
and add the following to .Xresources...
! meta key for emacs
XTerm*metaSendsEscape: true
!XTerm*eightBitInput: false
Bottom line does nowt in a UTF-8 terminal anyway.
Both emacs and mg work as expected in the tty console.

Slackware 14.2 and 15.0 uses .alpine.passfile as the name of the file to
store passwords. Alpine demands that you set a master password when
storing passwords. You can set one, store all the passwords for various
accounts, then rename the master password hash code and reencrypt as
follows...
<
https://askubuntu.com/questions/1349401/how-to-remove-the-master-password-for-the-alpine-pine-e-mail-client>

Texmacs 2.1.1 spell check on Slackware 14.2
===========================================
Texmacs 2.1.1 will compile on Slackware64 14.2 using the 14.2 slackbuild
with the source version modified. The only dependency is guile1.8, an
old version of guile which must be installed before compiling Texmacs.
You will need to compile the hunspell-en package as well to get spell
check working - if you don't you get an error console with loads of
"can't find en_GB" errors. I compiled all five english dictionaries. The
spell check is old school: you run spell and it finds errors which it
displays in a pane below the document, offering possible corrections for
you to select from. Useful for catching typos and less intrusive than
the underline in red kind.

Above script sits in my user bin and when I invoke it with a single word
argument it checks if I have asked for that word before. If I have, it
prints the definition from the Webster's 1913 Web site. If I haven't,
the script fetches the definition and saves it as a file in
~/bin/.websters and then displays the definition.
Amusingly if the word is not found the 404 page is saved for that word
so I get the 404 if I ask for the missing word again.
/home/keith/bin$ cat webster
#!/bin/sh
w="$1"

-----------------
Recompile gcc and emacs slackbuilds on Slackware-15.0 to enable native
compilation of elisp code for lutz and giggles.
Compiling emacs 28.2 with native compilation of elisp requires
rebuilding the gcc slackpackage and then modifying some of the emacs
compile options.
Download the Slackware 15.0 emacs source code to slackbuilds using...
rsync -av rsync://slackware.uk/slackware/slackware-15.0/source/d/gcc/ .
Add following line to emacs.SlackBuild script (becomes line 357) to add
the ./configure option for just in time compilation so libgccjit gets
built...
--enable-host-shared \
..then add `jit` to the list of languages in line 358
--enable-languages=ada,brig,c,c++,d,fortran,go,lto,objc,obj-c++,jit \
Finally, I usually increase the BUILD number in line 60 by 1 so that I
can upgrade the gcc packages once compiled using upgradepkg. I DON'T
blacklist gcc in slackpkg as I want to know if this fundamental
package is upgraded at all.
You end up with these eight gcc packages
/tmp/gcc-11.2.0-i586-4.txz
/tmp/gcc-brig-11.2.0-i586-4.txz
/tmp/gcc-g++-11.2.0-i586-4.txz
/tmp/gcc-gdc-11.2.0-i586-4.txz
/tmp/gcc-gfortran-11.2.0-i586-4.txz
/tmp/gcc-gnat-11.2.0-i586-4.txz
/tmp/gcc-go-11.2.0-i586-4.txz
/tmp/gcc-objc-11.2.0-i586-4.txz
It is an overnight compile on a core duo laptop with 3Gb ram.
I upgraded my gcc as follows...
# upgradepkg /tmp/gcc*-11.2.0-i586-4.txz
Now fetch the emacs source and SlackBuild script
rsync -av rsync://slackware.uk/slackware/slackware-15.0/source/e/emacs/ .
Delete the emacs version 27 source files
emacs-27.2.tar.xz
emacs-27.2.tar.xz.sig
Go to a GNU mirror and download the most recent release sources
emacs-28.2.tar.xz
emacs-28.2.tar.xz.sig
Then edit the SlackBuild as follows
Line 74 becomes
PDUMPER=${PDUMPER:-"--with-dumping=pdumper"}
This option is needed for native compilation - you'll get an error
without it. I've compiled and run the no-X emacs binaries (see below)
and I am not seing any errors (yet) when running `emacs -nw`. I might
redo this with explicit options for jit and pdumper in with-X build and
no pdumper or jit in no-X build if there are any problems.
Line 106 is where the ./configure options for the X version (GUI) of
emacs starts. Add
--with-native-compilation \
somewhere in there, I put mine on line 117 just before the with-X
option.
I also put the same option in the /configure options for the no-X
build, starting at line 146 (145 in the unmodified SlackBuild).
It is a two hour compile on the core duo. Then upgrade the emacs
package...
upgradepkg /tmp/emacs*.txz

Slackware 14.2 on X61s upgrading to firefox-102 esr generated a crash

Sed edit in place to remove Windows/Dos end of line characters from a
file I downloaded. The extra end of line character shows in vi as ^M.
sed -i 's/^M$//g' ~/Downloads/hosts.txt
You can't just write ^M, you have to enter control characters in bash
using Ctrl-V. So here we need to type Ctrl-V and Ctrl-M to enter the ^M
control character (line feed?) after the / and before the $ for end of
line.
I've got Slackware 15.0 on the 32bit X60 with fluxbox, thunar for
external stick management, a couple of system try applets for nm-applet
and for battery level. I've customised the `~/.fluxbox/init` and `keys`
files and hacked my own style. Menu items to suit my software. All nice.
Xfce4 is nice but getting heavy as it moves to GTK3.

On Slackware 14.2 on the X61s I use firefox-esr downloaded from Mozilla
and repackaged using the `firefox-latest.sh` script. This means you get
nags each time there is a minor upgrade to the Web browser in the form
of an annoying button on the toolbar that cannot be removed or silenced.
The work around is to use a policy, which must be in the /etc/ directory
(so machine wide policy).
$ cat /etc/firefox/policies/policies.json
{
"policies": {
"DisableAppUpdate": true,
"DisableFirefoxAccounts": true,
"DisableFirefoxStudies": true,
"DisablePocket": true,
"DisableTelemetry": true,

}
}
From
https://linuxreviews.org/HOWTO_Make_Mozilla_Firefox_Stop_Nagging_You_About_Updates_And_Other_Annoying_Idiocy
Added from the future 6th November 2023 for Slackware 15.0 and Firefox
ESR 115.4.
Firefox Suggest keeps giving bonkers one word web addresses with .com or
org on the end as the first match when I already have a perfectly fine

Console font on X60 with 1024x768 display. The Terminus font series is a
good compromise and the one below (setconsolefont script in Slackware)
fits around 72 characters in width.
bash-5.1$ cat /etc/rc.d/rc.font

#
# This selects your default screen font from among the ones in
# /usr/share/kbd/consolefonts.

X60 with OpenBSD i386 install using cwm. Seamonkey needs following...
@namespace url("

* {
font-size: 12pt !important;
}
as userChrome.css in the profile/chrome directory. Key is the asterisk -
matches all elements.
Also had to munge the hosts.txt file from WinHelp to use with unwind.
1) Get rid of windows returns with sed
2) Grep for lines starting with # character and -v them so only lines
that don't start with # included
3) Use the cut -c 9- command to get rid of the 0.0.0.0 prefix for use
with unwind on OpenBSD.

cwm on OpenBSD getting a coherent set of fonts on the L440 with its 1600
by 900 screen.
I've got 96dpi set in .Xdefaults...
! Font settings
Xft.dpi: 96
Xft.autohint: 0
Xft.lcdfilter: lcddefault
Xft.hintstyle: hintslight
Xft.hinting: 1
Xft.antialias: 1
Xft.rgba: rgb
! Use a nice truetype font and size by default...
xterm*faceName: DejaVu Sans Mono Book
xterm*faceSize: 14
..and 14pt font size for xterm and other Xft apps. I have the following
in gtkrc-2.0 for GTK+2 apps...
foo$ cat .gtkrc-2.0
gtk-font-name = "DejaVu Sans 16"
..and in .config/gtk-3.0/settings.ini...
foo$ cat .config/gtk-3.0/settings.ini
gtk-font-name = Sans 16
..but as always Firefox is the odd one out and does not respond to font
settings in styles. Firefox *does* respond to dpi settings but that
tends to increase the size of the space around the menu buttons and
tabs. You can use a userChrome.css setting to set a font for the menus
and buttons...
..and in .config/gtk-3.0/settings.ini...
foo$ cat .config/gtk-3.0/settings.ini

https://www.userchrome.org/how-create-userchrome-css.html
Use the about:profiles window to find current profile then go to that
profile's directory and create another directory called 'chrome'
In the chrome directory create the file userChrome.css with contents like
this...
foo$ cat userChrome.css
/* global font */
* {
font-family: DejaVu, sans-serif !important;
font-size: 16pt !important;
}
Then use about:config to switch on 'legacy' user style sheet settings
by setting the key...
toolkit.legacyUserProfileCustomizations.stylesheets
..to true
Fairly coherent set of font sizes all through then.

Slackware 15.0 is out so reinstalled from iso on X60 as test machine.
Used encypted home drive as per README_CRYPT.TXT. Didn't want to lose
configs so used idea from
https://stackoverflow.com/questions/4572973/archiving-hidden-directories-with-tar
Basically, tar up your whole home drive to /var/tmp (user writable)
tar czpf /var/tmp/home.tgz .
Trailing dot is important. Wildcards won't expand to dotfiles.
Copy the home.tgz to external hard drive.
Reinstall.
Copy home.tgz back to /home/user and untar using...
tar xvf home.tgz
..log out/log into xfce4 and resume browsing the tabs you had open in
Firefox...

Slackware 15.0RC: the version of ssh installed is depreciating RSA
keys for ssh sessions. Below is a work around until I check with
mythic about updating their ssh.
[17:50]~$ cat .ssh/config
Host some-server.com
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
RSAMinSize=1024
Otherwise all good.
Added 16th March 2023: Last line is for Fedora 37+ because they now set
minimum RSA key length to 2048. See

xvi is a stevie based vi clone from back in the day. If you install the
POSIX version you get a bare bones vi that does not recognise backspace
or the arrow keys thus forcing you to use the hjkl and other movements.
The INSTALL and doc/README instructions for posix work fine but on
Slackware I need to symlink the man file as follows...
ln -s /usr/local/share/man/man1/xvi.1 /usr/man/man1/
Having run make within the docs folder, I have a nice pdf formatted man

Half way down page. Could be useful for removing duplicates from the

"When I take a backup of my Psion, I simply copy the contents of the disk
to a directory whose name is today's date. This gives me a large
collection of directories, nearly one per day, whose contents are nearly
identical. I then index each one using this comment:
find $new -type f -exec md5sum '{}' ';' | sort -k 2 > $new.ndx
Now I delete all the identical files from the older directory like this
diff -rqsb $old $new | gawk '/identical$/{print $2}' | xargs rm
It has a problem if there are filenames with spaces."

T60 with the Slackware 14.1 install with seamonkey.
https://www.linuxquestions.org/questions/slackware-14/how-do-i-change-default-sound-card-in-slackware-14-2-without-x-4175644839/
How to reorder the sound devices using the module loading order. What we
want...
bash-4.2$ cat /proc/asound/modules
0 snd_hda_intel
1 snd_pcsp
29 thinkpad_acpi
Originally the pcsp was listed first. So make a file
/etc/modprobe.d/alsa-base.conf and add following...
options snd slots=snd_hda_intel,snd_pcsp,thinkpad_acpi
options snd_hda_intel index=0
options snd_pcsp index=1
After reboot, Audacity &c work as expected. Recording in Audacity before
this was glitch special as it sampled the power rails for the bleep!
LibreOffice 6.4 binaries won't pick up the gtk theme as the gtk3 version
is too old to use with libreoffice-gtk rpm from CentOS 7. Using default
fallback vcl=x11 produces very small fonts. Using .Xresources at dpi:120
to make them bigger. My backport the 14.2 gtk3 and see what happens...
April 29th 2021
---------------
Slackware64 14.1 install on 60Gb SSD on the Atheros X61s with kernel
packages from 14.2 /patches. I'm also using Seamonkey 2.53.7.1 binaries
from the Seamonkey project site - unpack, mv to /opt/seamonkey and set
paths and preferences. Along with Apache OpenOffice you get a very
usable desktop.
Lyx from slackbuilds provides a WYSIWYW interface for writing - it is
limited by the TeX backend, in the case of Slackware prior to
15.0/current that was basic as provided by XeTeX. Part of this is rough
looking fonts in pdf files.
https://askubuntu.com/questions/98664/how-can-i-get-smooth-fonts-in-lyx
Native TeX is provided by XeTeX which is, as mentioned, *old*...
bash-4.2$ tex --version
TeX 3.141592 (Web2C 7.5.4)
kpathsea version 3.5.4

Kpathsea written by Karl Berry and others.
So when compiling Lyx against this, you will end up with poor quality
fonts in Lyx 2.1.4 from slackbuilds, strange, as TeX and LaTeX give fine
sharp fonts. The work around is to add this...
% set fonts for nicer pdf view

mkdir -p ~/.themes/blank/xfwm4 && touch ~/.themes/blank/xfwm4/themerc
Make a blank theme file in xfce4 as above. You will have *no title bar*
at all. Alt F10 to maximise, Alt drag to move a window. You can't resize
windows except by making a keyboard shortcut to the resize command
https://www.xfce-look.org/p/1016214/
Borders only theme...much better. Can resize by dragging and get the
window menu by right clicking and can move with some mouse accuracy.

I've decided not to use compression (.tar.gz) as most files are
* text files (size is rounding error)
* packages or image files or audio files (compressed already)
You can directly open an incremental tar and extract a dated

Trick for avoiding the file system full errors on / on a cheap linode

As root, in good times
# xfs_mkfile 10240m 10gig
# chmod 777 10gig
As user, when disk space runs out
$ > 10gig
Above redirection from nowt over rites the 10gig file with a 0 byte
file, freeing some space. Other tricks include patitioning / /var and
/home separately. As well as partitions not filling the disk &c

Updating current slackware
++++++++++++++++++++++++++
https://stackoverflow.com/questions/9522631/how-to-put-a-line-comment-for-a-multi-line-command
and especially
https://stackoverflow.com/a/12797512
Clever use of backticks: cost is one shell spawned and closed for each
comment. And extra lines in your history. It is a bashism.
Makes possible this rsync command line to sync my local current
folder, run as user, chmod +x and use ./syncslack...
rsync -av \
--delete \
--exclude=slackware64/kde \
--exclude=slackware64/y \
--exclude=source \
--exclude=pasture \
rsync://rsync.mirrorservice.org/ftp.slackware.com/pub/slackware/slackware64-current/ /home/keith/Downloads/current
With plenty of hard drive space (500Gb spinning rust) I just copy the
current folder and change the name of the copy to a date, then sync the
current folder. If anything nukes the installation, I can revert to the
previous one.
As root use
# upgradepkg --install-new /home/keith/Downloads/current/slackware64/*/*.txz
to upgrade packages. Find new configuration files with
# find /etc -name *.new
Then use diff to see what the changes are...
# diff /etc/someapp.conf /etc/someapp.conf.new
Slackware 15.0 Alpha looking really good by the way. Plasma is even
usable, the UX seems to have become more sensible.
KDE Plasma and Apache OpenOffice
++++++++++++++++++++++++++++++++
Change permissions on the desktop files as below...
# chmod +x /opt/openoffice4/share/xdg/*.desktop
Runs fine from Application Launcher then. No need to change executable
path in the desktop file.

Slackware 14.2 on the T61p with nvidia drivers 340.xxx installed from
the nvidia bin file. It clobbers some of the *.la files needed to
reference libraries. It saves the files it overwrites in /var/lib/nvidia
but as files with integer names! To find which integer is what file you
have to grep the nvidia log...
bash-4.3# grep ".la" /var/lib/nvidia/log
101: /usr/X11R6/lib64/modules/libglamoregl.so
102: /usr/X11R6/lib64/modules/libglamoregl.la
104: /usr/X11R6/lib64/libGLESv2.la
105: /usr/X11R6/lib64/libGLESv1_CM.la
106: /usr/X11R6/lib64/libGL.la

1: /usr/share/doc/NVIDIA_GLX-1.0/html/installationandconfiguration.html
1: /usr/lib64/libGL.la
To get some compiles to complete you
have to copy some of the *.la files back as follows...
bash-4.3# cp /var/lib/nvidia/106 /usr/X11R6/lib64/libGL.la
bash-4.3# cp /var/lib/nvidia/110 /usr/X11R6/lib64/libEGL.la
I did...
bash-4.3# cp /var/lib/nvidia/110 /usr/lib64/libEGL.la
bash-4.3# cp /var/lib/nvidia/106 /usr/lib64/libGL.la
..because that is where the libraries are on slack.

Compiling Abiword and Gnumeric on the X60 with a 32 bit minimalish

evince (runtime only -> xpdf redirect)
~/.gtkrc-2.0 file: gtk-print-preview-command="xpdf -q %f"
All works fine. Abiword 3 versions alas use the GTK3 style hide and seek
scroll bars.
As this is a thin install, I have not installed xap, xfce, kde, emacs at
all. Using twm as the window manager, and a customised .xinitrc file to
start Xorg.
Below is the .twmrc
#
# Default twm configuration file; needs to be kept small to conserve string
# space in systems whose compilers don't handle medium-sized strings.
#
# Sites should tailor this file, providing any extra title buttons, menus, etc.
# that may be appropriate for their environment. For example, if most of the
# users were accustomed to uwm, the defaults could be set up not to decorate
# any windows and to use meta-keys.

Slackware 14.2 on the Thinkpad L440 with its horrid trackpad.
https://askubuntu.com/questions/370505/how-to-use-trackpoint-but-keep-touchpad-disabled-on-lenovo-thinkpad-e531
Turns out you can stop the trackpad acting as a mouse and use it just to provide
the left, middle, right buttons as below...
bash-4.3$ cat /etc/X11/xorg.conf.d/50-synaptics.conf
# DO NOT EDIT THIS FILE - IT WILL BE OVERWRITTEN ON UPGRADES
# Copy this file to /etc/X11/xorg.conf.d/ and edit the copy
#
# Use "synclient -l" to see all available options
# Use "man synaptics" for details about what the options do
#
Section "InputClass"
# Identifier "touchpad"
# Driver "synaptics"
# MatchDevicePath "/dev/input/event*"
# MatchIsTouchpad "on"
# Option "TapButton1" "1"
# Option "TapButton2" "2"
# Option "TapButton3" "3"
Identifier "Default clickpad buttons"
MatchDriver "synaptics"
Option "SoftButtonAreas" "64% 0 1 42% 36% 64% 1 42%"
Option "AreaBottomEdge" "1"
EndSection
The commented out lines are the example lines from /usr/share and they tell you
the default.

Mystery now solved for Slackware using the default KDE 4.14 as used in
Slackware current and 14.2. A default install gives a nice usable
desktop BUT Firefox will show tiny fonts in menus and other parts of the
UI. To allow adjustment of font sizes in GTK applications you need to
install a slackbuild package, kde-gtk-config. For current, I just
compiled the 14.2 slackbuild and it is working fine. Compile, install
the package, log out of KDE and log in again. You will find a new
component in Application Appearance - just set the font size to 12 to
generate the configs.

This has been bugging me for ages...

------------------
Installing Chromium on slackware current or 14.2. When the program
starts, it asks for a keyring password for its own password store
function on xfce4. I don't use a local keyring, so I set chromium to use
unsafe storage by adding an argument to the exec line in the desktop
file...
nano --nowrap /usr/share/applications/chromium.desktop
Line 108 now reads...
Exec=/usr/bin/chromium --password-store=basic %U
I also switch off the password store setting in Chromium preferences...

-----------------
Slackware current installing LibreOffice 6.2 from the libreoffice.org
binaries has got a bit more complex than it usually is.
At present you need to
* Unpack libreoffice and convert the rpms to tgz using rpm2tgz
* Install the rpms
* Set an environment variable to tell LO not to look for wayland
* Install avahi, which has a dependency on libdaemon, so install libdaemon.
* Set avahi up to start on boot and stop on shutdown using /etc/rc.d/rc.local
Set environment variable
------------------------
Temporary: just run
export SAL_USE_VCLPLUGIN=gtk
as user in bash, then run Writer or Calc
Permanent
Add a script to /etc/profile.d/libreoffice.sh with contents
#!/bin/sh
export SAL_USE_VCLPLUGIN=gtkbash-5.0$
Install avahi and configure daemon
----------------------------------
Impress now has a dependency on avahi daemon, because someone decided
that the ability to remote control Impress was really vital. See the bug report at
https://bugs.documentfoundation.org/show_bug.cgi?id=119408
Avahi depends on libdaemon, so
https://github.com/Ponce/slackbuilds/tree/current/libraries/libdaemon
Build and install libdaemon
Then *before* building avahi, create an avahi group and user
# groupadd -g 214 avahi
# useradd -u 214 -g 214 -c "Avahi User" -d /dev/null -s /bin/false avahi
Then build and install avahi using
https://github.com/Ponce/slackbuilds/blob/current/network/avahi/
Then add the following to the /etc/rc.d/rc.local script
# Start avahidaemon
if [ -x /etc/rc.d/rc.avahidaemon ]; then
/etc/rc.d/rc.avahidaemon start
fi
# Start avahidnsconfd
if [ -x /etc/rc.d/rc.avahidnsconfd ]; then
/etc/rc.d/rc.avahidnsconfd start
fi
And create /etc/rc.d/rc.local_shutdown and add the following
# Stop avahidnsconfd
if [ -x /etc/rc.d/rc.avahidnsconfd ]; then
/etc/rc.d/rc.avahidnsconfd stop
fi
# Stop avahidaemon
if [ -x /etc/rc.d/rc.avahidaemon ]; then
/etc/rc.d/rc.avahidaemon stop
fi
Then you can load Impress and Draw without error messages.

Fedora 29 on the L440.
Make powertop settings persistent
https://fedoramagazine.org/saving-laptop-power-with-powertop/
$ sudo systemctl start powertop.service
To set all settings to good for current session
$ sudo systemctl enable powertop.service
Created symlink /etc/systemd/system/multi-user.target.wants/powertop.service → /usr/lib/systemd/system/powertop.service.
Above unit file symlink makes changes permanent.
Fonts: set slight hinting and rgba sub-pixel hinting as follows
https://askubuntu.com/questions/70606/how-to-enable-sub-pixel-hinting
Find out what settings are now...
$ gsettings get org.gnome.settings-daemon.plugins.xsettings hinting
$ gsettings get org.gnome.settings-daemon.plugins.xsettings antialiasing
Change settings if you need to...
$ gsettings set org.gnome.settings-daemon.plugins.xsettings hinting slight
$ gsettings set org.gnome.settings-daemon.plugins.xsettings antialiasing rgba
Sub-pixel hinting should 'just work' after updating Fedora 29 as the new
unencumbered freetype is provided.

Slackware: to make Powertop changes permanent on boot, add the lines
below to /etc/rc.d/rc.local
powertop --auto-tune

The exit 0 line is the last line of the script. The default rc.local
file just has a comment at the top explaining what it is for.
https://askubuntu.com/questions/112705/how-do-i-make-powertop-changes-permanent
When using a window manager (i.e. no conveniences such as a system try
with a battery icon) the following bash alias can be useful...
alias bat='upower -i /org/freedesktop/UPower/devices/battery_BAT0| grep -E "state|to\ full|percentage"'
Slackware comes with a choice of built-in light window managers.
Blackbox with the panel turned off is a favourite of mine. Copy the
/usr/share/blackbox/menu file to ~/.blackbox/menu and set permissions to
something like 755 for your user. Then edit to customise the menu.

Debian Stretch live iso
Networking with usb driver rtl8187, network-manager can see the driver,
kernel module loaded &c but new long interface names prevent using
network-manager from connecting. Had to fall back on
/etc/network/interfaces file like this...
oot@debian:~# cat /etc/network/interfaces
#auto lo
#iface lo inet loopback
auto wlx0026f2gunge
iface wlx0026f2gunge inet dhcp
wpa-ssid wifiname
wpa-psk wifipass
To stop network-manager and restart the networking service from within
an existing session, you need to do following
# /etc/init.d/network-manager stop
# systemctl restart networking.service
To find out the long name for the wifi interface, use
# ip a
To scan for the ssid use
# ip link set wlx0026f2gunge up
# iwlist scan
For permanent install, probably easier to just set the configuration to
use the old non-unique interface names like wlan0 &c or hope they fixed
the bug.
You can set the old names at boot by pressing Tab and adding
net.ifnames=1
to the kernel bootline like we used to do with nomodeset back in the
day.
Bug is #842422 and relates to older generation 802.11bg wifi devices!

Installing Sage Math 8.3 from binary on Slackware current
* Download the Fedora 28 binary Linux 64 bit tar.bz2 file, all 1.6Gb
* As user extract with tar xvjf sage-8.3-Fedora_28-x86_64.tar.bz2
* As root mv SageMath /opt/
* As user /opt/Sage/Math/sage
* Will start in command line
* To run notebook() in Web browser, you need an extra library
* Download libxcrypt-4.1.2-1.fc28.x86_64.rpm
* As user convert to tgz with rpm2tgz
* As root installpkg libxcrypt-4.1.2-1.fc28.x86_64.tgz
* From within a sage cli session run notebook()
* You will be asked to set a password
* Browser will open and allow choices such as new workbook
* Local doc tree at file:///opt/SageMath/local/share/doc/sage/html/en/index.html
* Slackware current has texlive and ffmpeg so should be OK for

September 11th 2018
-------------------
Using procmail as MTA instead of sendmail. You need to add a line to the
fetchmailrc file from yesterday...
# set username
set postmaster "user5"
# set polling time (5 minutes)
set daemon 600
poll pop.gmail.com with proto POP3
user '
[email protected]' there with password 'secretpassword' is use$
mda "/usr/bin/procmail -m '/home/user/.procmailrc'"
And then set up a 'recipe' in .procmailrc
LOGFILE=$HOME/.procmail.log
MAILDIR=$HOME
VERBOSE=on
:0
Mail/inbox/
The :0 bit is the start of a recipe. The trailing slash on Mail/inbox
says to use the Maildirs format (each message in its own file) as
opposed to the mbox format (all messages in one large file). I will
match various mail accounts to different folders in the future by using
different recipes. It will also be possible to have e.g. mailing list
messages sorted into different mail boxes.
Then use the verbose command line to (re)fetch the email again...
$ fetchmail -d0 -vk pop.gmail.com
I deleted the spool file and then did
# touch /var/spool/mail/user
So there was a spool file to re-read. The spool has remained empty
since.
I have not included commands to delete mail off the server in
fetchmailrc as yet so I can play about with settings &c. You need to
delete the .fetchids file and the .procmail.log file if you want to
refetch the mails left on the server for testing purposes.
Next move is to set up mutt to read the folders. Then sort out how to
send mail, copy the sent mail to a sent folder and use the smtp auth
settings for my ISP.
September 10th 2018
-------------------
Fetchmail on Slackware 14.2
https://www.axllent.org/docs/view/gmail-pop3-with-fetchmail/
Examples below show gmail download as on original site but I've tested
this with mythic's pop3 and mail server and it works fine.
First check certificates are installed correctly for ssl
openssl s_client -connect pop.gmail.com:995
Then make a .fetchmailrc configuration file like this...
# set username
set postmaster "user5"
# set polling time (5 minutes)
set daemon 600
poll pop.gmail.com with proto POP3
user '
[email protected]' there with password 'secretpassword' is user5 here options ssl
Then for Slackware default install, you have to run sendmail so
fetchmail has something to hand the mail onto
# chmod +x /etc/rc.d/rc.sendmail
# /etc/rc.d/rc.sendmail start
# exit
Then run fetchmail with flags that let you see the dialogue with the
remote server
fetchmail -d0 -vk pop.gmail.com
The mail should be downloaded from the pop3 mailbox and be 'sent' to
your mail spool at /var/mail/user by smtp
The mail is in a single spool file and has an extra header on each
message recording the send date from sendmail
After testing, I just disabled sendmail
# /etc/rc.d/rc.sendmail stop
# chmod -x /etc/rc.d/rc.sendmail
# exit
because I want to use procmail to sort my stuff into folders.
But 'fetchmail and grep' is entirely feasible.

-----------------
Removed OpenOffice 4.1.3 and installed OpenOffice 4.1.4
Because OpenOffice is installed by converting the rpms to tgz packages
from the binary distribution on the OpenOffice Web site, you have to
remove all the packages using removepkg. You can generate a list of the
packages on one line with spaces separating them using the command
ls /var/log/packages | grep openoffice | tr '\n' ' '
Then I just copy that list from the terminal into the argument line of
removepkg. Finally, install OpenOffice from the converted tgz files in
the usual way.

}
Above added to .bashrc and sourced will provide a basic note recording
function in a terminal window. Use of the built-in bash command read
with the -e flag provides line editing (backspace delete and arrows as
well as emacs style keyboard shortcuts). The -r option disables the \
expansion. No other expansion takes place so you can have " and ! and '
in your note.
Currently one line per note prefixed with the date/time down to the
second so can use cat .notes | grep 201710 to list all October notes.

Incremental backups using tar. The idea is to back up a directory of my
home drive under my user and then keep a series of snapshots.
$ tar cvfz /home/keith/backups/$(uname -n)-$(date +%Y%m%d-%H%M).tar.gz -g /home/keith/backups/$(uname -n).snar Documents
Each time the above command is run, the current contents of the Teaching
directory is checked against the previous contents and the differences
are saved as the next archive.
The first time you run the command the *.snar file is created and the
whole directory is copied to an archive and compressed. That is called a
level 0 backup.
The second time you run the command, a second tar.gz file is created
that contains the differences between the current state of the directory
and the first archive. This is the level 1 backup.
The third time the command is run, a new archive is created with just
the differences between the second and third archive. And this is a
level 2 backup.
You are creating a chain of backups.
To restore the current state of the directory, you use the command
$ tar xvf backups/<each archive in turn, highest level first>.tar.gz
So you are unwinding the chain from the earliest to latest.
I'm interested in using this to 1) save storage space and duplication
and 2) preserve snapshots of my home drive say each week to allow
reverting to an earlier state.

Fedora 26 on X220 with texlive-scheme-full and the usual suspects.
https://www.reddit.com/r/Fedora/comments/5nfenw/better_looking_fonts_for_fedora/
Installing nicer font defaults and sub-pixel rendering leads to conflict
with a texlive font family, the 'cabin' fonts, and they are a dependency
of the copr package. Don't want to remove the whole of texlive
especially, so fell back on the hack below...
https://www.reddit.com/r/Fedora/comments/36ssd7/how_to_replace_one_package_with_another_using_dnf/
rpm --nodeps -e foo
dnf install foo-alt
Font package from texlive removed and that allows installation of the
conflicting font package (hopefully supplying identical fonts, but we
shall see).

Installing RStudio from the .deb binary downloaded from the Web site
fails on Debian Stretch. The binary installation expects to find three
libraries from Jessie vintage. As a quick hack, downloading debs of
those libaries and installing them using dpkg on stretch does not appear
to have broken anything. We'll see what happens when libraries are
upgraded.
rstudio-1.0.143-amd64.deb
dpkg -i libgstreamer0.10-0_0.10.36-1.5_amd64.deb
libgstreamer-plugins-base0.10-0_0.10.36-2_amd64.deb
libssl1.0.0_1.0.2l-1~bpo8+1_amd64.deb
Also using lxde or MATE desktop, the fonts within the RDesktop
application are not antialiassed. Adding an appropriate fonts.conf file
to ~/.config/fontconfig sorts that out.

Installed Debian Stretch on X61s with LXDE interface. Comes with wicd
and wireless-tools rather than network-manager. Wicd depends on iwlist
scan command (or appears to) to discover list of wifi connections.
iwlist barfs with ~200+ connections, each with 30 lines of info. So Wicd
can't connect because can't list any connections. The 'iw wls3 scan'
command will list connections, and, for unencrypted public wifi you can
connect just using...
# iwconfig wls3 essid "some daft name"
# dhclient wls3
For encrypted connections it gets tricker, so I used logical interfaces
within the /etc/network/interfaces file having uninstalled
wicd/wireless-tools (so no ifconfig and no iwconfig)...
keith@saucer:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
iface home inet dhcp
wpa-ssid name-of-home-wifi
wpa-psk home-passphrase
iface phone inet dhcp
wpa-ssid name-of-phone-wifi
wpa-psk phone-passphrase
iface open-wifi-nick inet dhcp
wpa-ssid "name of open wifi with quotes if spaces"
wpa-key-mgmt NONE
invoke logical interfaces above by
# ifup wls3=home
do stuff, go out, switch on phone hotsopot
# ifdown wls3=home
# ifup wls3=phone
do stuff outside
# ifdown wls3=phone
# ifup wls3=open-wifi-nick
do stuff using free wifi
# ifdown=open-wifi-nick
Go and read a book instead
Reference: 10.6.2 High level network configuration using ifupdown
logical interface definitions in Debian reference. Need to see what to
do with open interfaces.
To connect to unencrypted wifi just use
# iw dev wls3 connect your_essid
# dhclient wls3 (I'm guessing)
Above won't work if logical interfaces defined in
/etc/network/interfaces

Debian Stretch from blu-ray iso dd'ed to a USB stick. You have to do a
waggle dance to get the USB stick recognised by Stretch as a deb
repository. The steps are...
# umount /dev/sdb1 # unmounts the automatic mount to /media/keith/"Debian 9.0.0 amd64 1"
# mkdir /media/cdrom/"Debian 9.0.0 amd64 1" # puts a mount point somewhere with appropriate permissions
# mount /dev/sdb1 /media/cdrom/"Debian 9.0.0 amd64 1" # mount the stick as an image
# cat /etc/apt/sources.list # entry below needed in sources.list
deb [trusted=yes] file:/media/cdrom/"Debian 9.0.0 amd64 1"/ stretch main contrib
And finally, after downloading a 21Gb iso using jigdo, you can't install
texlive-full because of a missing file called
http://ftp.debian.org/debian/pool/main/f/fragmaster/fragmaster_1.7-5_all.deb.
So I downloaded that 120Kb package and used
# deb -i --force-depends fragmaster_1.7-5_all.deb
Then installed texlive-full, got a tonne of errors and ran
# apt-get --fix-broken install
That seems to have worked. Will raise a bug.

Installing infinality patched font rendering libraries on Slackware. See
http://www.linuxquestions.org/questions/slackware-14/how-to-optimize-fonts-in-slackware-640468/page34.html
First install the lxml library and its dependencies...
BeautifulSoup4-4.4.1-x86_64-1_slack.txz
html5lib-0.9999999-x86_64-3_slonly.txz
lxml-3.8.0-x86_64-1_slonly.txz
six-1.10.0-x86_64-2_slonly.txz
Then clone the git repository and run the script to compile the infinality patched libraries
$ mkdir infinality
$ git clone
https://github.com/archfan/bob-infinality-bundle.git ~/infinality
$ cd infinality
$ pwd
# su -
# cd cd /home/keith/infinality
# chmod +x install.sh
# ./install.sh
Finally symlink the font specification files...
# ln -s /etc/fonts/conf.avail.infinality/ms/* /etc/fonts/conf.d/
Note: this replaces the following stock slackware libraries
Freetype 2.6.5
Cairo 1.4.6
Fontconfig 2.11.95
so keep an eye on patches for those. I copied the contents of the tmp folder back to a slackbuilds folder...
$ bash-4.3$ ls /tmp/bob-infinality-bundle/
cairo-1.14.6 fontconfig-2.11.95-x86_64-1.txz package-cairo
cairo-1.14.6-x86_64-1.txz freetype-2.6.5 package-fontconfig
fontconfig-2.11.95 freetype-2.6.5-x86_64-1.txz package-freetype

"In general, I typically don't update my kernels using slackpkg. It
isn't recommended, even if it is enabled by default (see the below text
from /etc/slackpkg/blacklist). Rather, I will download the kernels
manually, run installpkg on them (instead of upgradepkg so it keeps the
old kernels in place in case something goes wrong), generate a new
initrd if requires, then update my lilo.conf to add the new kernel. Then
I'll run lilo and reboot. If there are no glaring problems, I can then
removepkg the old kernel packages."
March 4th 2017
--------------
Installed Slackware Current on X61s from alienbob's 64bit iso (dated 1st
March). Installed everything including kdei except games (Y) - can't
stand the fortune cookies. Using KDE with effects off and Dolphin set to
double click to open &c.
To get Amarok to play an mp3, you need to install the gst-plugins-ugly
package from slackbuilds. I just used the 14.2 version from slackonly.
I've installed LibreOffice 'still' (4.2.5) version from the LO Web site
using rpm2tgz. Works fine. As usual, you need to pick a theme that
allows the tickboxes to be visible within LO. I added the UK English
help and LangPack files.
Inkscape had to be compiled using the new slackbuild for version 0.92 as
previously compiled binaries won't find ImageMagick library as version
is higher in Slackware Current (previous binaries want 0.6 and install
has 0.7).
https://github.com/Ponce/slackbuilds/tree/current/graphics/inkscape
Shows two dependencies, numpy and lxml. I did not install either of
those, locate finds a numpy and a couple of xml like libraries. There
could be missing functionality. Compiled in around 2 hours.
R installs fine from a previous 14.2 compile, and the RStudio Desktop
rpm file converts easy using rpm2tgz. No extra libraries needed.
February 14th 2017
------------------
Upgraded the 14.1 installation on the X220 with the 500Gb hard drive.
New kernel. Forgot to update lilo. Boot complains about invalid lzma. So
booted of Ubuntustudio live USB and chrooted into the Slackware root as
follows (straight out of the docs)...
$ sudo su # becomes root in Ubuntu live session, no password
# mount /dev/sda2 /mnt # as per slackware installer and docs
# mount -o bind /proc /mnt/proc
# mount -o bind /sys /mnt/sys
# mount -o bind /dev /mnt/dev
# chroot /mnt
# lilo # generates the new vmlinuz I think or at least new links
I'm being lazy and using the huge kernal and no initrd image. I might
reinstall with full hard drive encryption and then I would need to
generate a new initrd (see down the page).
MATE desktop with no xfce or KDE. I had to install a few xfce4 packages
to get xfburn working, and I have to use evince to be able to print to
file with 4 or 16 pages on one page (I do this to create flashcards).
Otherwise all fine.
February 7th 2017

-----------------
Installing R and RStudio Desktop on a Centos 6 based system has become
complicated because of the age of the libraries. Basically, recent
RStudio versions need a newer QT library and won't install. Older legacy
RStudio versions won't work fully with the current R version 3.2.x
branch because the way R does graphics has changed. So I compiled an
older R version from source and used a legacy version of RStudio
Desktop. RStudio Desktop *looks as if* it has hard wired paths for
certain libraries so you have to force installation using the --nodeps
option with rpm. The required libraries are there but at
/usr/local/lib/R/lib and not where the rpm package thinks they need to
be. All good fun.
On a fresh install of Stella Linux updated to 6.8 it goes like this...
#yum grouplist # Install compilers, X headers and texlive and headers for readline
#yum groupinstall 'Development Tools'
#yum groupinstall 'Desktop Platform Development'
#yum groupinstall 'TeX Support'
#yum install readline-devel
#cd Downloads
#wget -c

#./configure --enable-R-shlib
#make
#make install
#rpm -i --nodeps

Installing the Pure Data music syntheis package using the slackbuild without
jack audio on a 64 bit Slackware installation, you run into an issue about hard
wired path names in the main file of pure data.
https://www.mail-archive.com/pd-list@iem.at/msg61548.html
The mailing list thread above contains the details. Pure data expects /usr/lib
and on Slackware 64 we are in /usr/lib64. My gonzo workround is to edit line 517
of s.main.c as shown below...
#ifdef _WIN32
sys_libdir = gensym(sbuf2);
#else
strncpy(sbuf, sbuf2, MAXPDSTRING-30);
sbuf[MAXPDSTRING-30] = 0;
strcat(sbuf, "/lib64/pd");
if (stat(sbuf, &statbuf) >= 0)
{
/* complicated layout: lib dir is the one we just stat-ed above */
sys_libdir = gensym(sbuf);
}
else
{
/* simple layout: lib dir is the parent */
sys_libdir = gensym(sbuf2);
}
#endif
}
I really must learn how to make a patch file! There might be an environment
variable called LIBDIRSUFFIX defined by the make script so one respondent in the
mailing list suggests
sed -i -e "517s|lib/pd|lib${LIBDIRSUFFIX}/pd|" src/s_main.c
as a patch method. I'd like to make an actual .patch file that can be put in the
slackbuild directory as a project.

How to manage a self-built kernel. Remember that Slackware
will always need an initrd.
Installed Plasma 5 on 14.2 after trying out OpenSuse 42.1.
OpenSuse multimedia appears to be completely broken so just
went with Alien Bob's Plasma 5 build for stable Slackware.
Steps
1) Install Slackware 14.2 without kde/kdei
2) Create a directory somewhere convienient
(~/Downloads/slackware) and use the following command...
$ rsync -av --exclude=x86 rsync://alien.slackbook.org/alien/ktown/14.2/5 .
(above is run as the update method as well together with the
commands below at 4)
The trailing full-stop means 'copy to here' and avoids all
the crud directories you get with wget.
3) Log out of X (I use startx)
4) As root go into the directory '5' and issue the commands...
# upgradepkg --reinstall --install-new x86_64/deps/*.t?z
# upgradepkg --reinstall --install-new x86_64/deps/telepathy/*.t?z
# upgradepkg --reinstall --install-new x86_64/kde/*/*.t?z
5) Run xwmconfig as user and set Plasma (last on the list for
me) as the window manager.
6) startx and enjoy
7) Add the following kde apps
calligra-2.9.11-x86_64-5.txz
k3b-2.0.3-x86_64-2.txz
kplayer-0.7.2-x86_64-2.txz
kwebkitpart-1.3.4-x86_64-2.txz
oxygen-gtk2-1.4.6-x86_64-2.txz
So you can run Krita and all. No issues so far.
September 24th 2016
-------------------
Removed the kde packages and then just added
installpkg calligra-2.9.11-i586-5.txz kde-runtime-4.14.3-i586-3.txz kde-workspace-4.11.22-i586-4.txz kdelibs-4.14.21-i586-1.txz kactivities-4.13.3-i586-2.txz oxygen-gtk2-1.4.6-i586-2.txz oxygen-icons-4.14.3-i586-2.txz libkexiv2-4.14.3-i586-2.txz
and Krita and Karbon seem to run ok (as do other parts of Calligra for
some values of OK).
See
https://forum.kde.org/viewtopic.php?f=137&t=96675
for the basics then just running krita from terminal and tracking down
the missing libraries.
September 23rd 2016
-------------------
Installed the kde/kdei packages to try out karbon and krita, both part
of a monolithic Calligra package, and both needing kde libraries.
Removed most of the KDE applications to de-clutter the menus. Krita
apparently does not rely on the plasma desktop itself, just the
underlying libraries, so it may be possible to remove most of the kde
desktop.
Fetched the patches using the wget line
wget -r -nH --no-parent --reject=index.html* --cut-dirs=1 --no-clobber
http://slackware.uk/slackware/slackware-14.2/patches/packages/
The --no-clobber option means that I can just use the same directory to
incrementally add the changed packages. Running upgradepkg over that
directory installs just the changed ones.
September 20th 2016
-------------------
Slackware 14.2 continues to be stable. Compiled inkscape from the
slackbuild with a minor tweak to allow for having to use a different
location for the source code for one library (lxml).

All good. Mirror set to 14.2 on mirrorservice now. I always select
Prompt(P) when slackpkg tells me that there are new config files, and I
accepted the Overwrite(O) option for most except for slackpkg mirrors
and blacklist.
After the initial slackpkg update-all command, I got a notification
about slackpkg itself being updated, then had to reinstate the blacklist
(I block kde/* and kdei/* as I don't use KDE).

Installing the Oracle Virtualbox on Slackware 14.1 32 bit
I used the microlinux packages available from
http://www.microlinux.fr/microlinux/extras-14.1-32bit/slackware/xap/
and downloaded the four packages
bash-4.2$ ls vir*
virt-manager-1.2.1-i486-2_microlinux.txz
virtualbox-5.0.20-i486-1_microlinux.txz
virtualbox-extension-pack-5.0.20-i486-1_microlinux.txz
virtualbox-kernel-5.0.20_3.10.17_smp-i486-1_microlinux.txz
Then I installed those using
$su -
# installpkg vir*
Then I went to /etc/rc.d and found the following new init scripts...
# ls -1 /etc/rc.d/rc.v*
/etc/rc.d/rc.vboxautostart-service
/etc/rc.d/rc.vboxballoonctrl-service
/etc/rc.d/rc.vboxdrv
I just enabled one of those
# chmod +x /etc/rc.d/rc.vboxdrv
Then, as per the slackbuild 14.1 README.SLACKWARE at
https://slackbuilds.org/slackbuilds/14.1/system/virtualbox/README.SLACKWARE
I installed the vboxdrv kernel drivers...
# modprobe vboxdrv
# modprobe vboxnetadp
# modprobe vboxnetflt
and created the vboxusers group and added my user to it...
# groupadd -g 103 vboxusers
# usermod -G vboxusers keith
Then I started the kernel drivers manually...
# /etc/rc.d/rc.vboxdrv start
And ran Virtualbox from the XFCE4 application menu, and set up a VM for
Linux,Other to try out the Trisquel 64 bit iso. The speed is quite good
on the X220 - slower than native and 2d graphics but quite nice given
the arch difference (64 bit iso running on 32 bit host).
Then so the kernel drivers load each time I reboot, I added the lines to
/etc/rc.d/rc.local and /etc/rc.d/rc.local_shutdown recommended in the
slackbuild readme...
/etc/rc.d/rc.local
# Start vboxdrv
if [ -x /etc/rc.d/rc.vboxdrv ]; then
/etc/rc.d/rc.vboxdrv start
fi
Loads kernel module.
/etc/rc.d/rc.local_shutdown
# Stop vboxdrv
if [ -x /etc/rc.d/rc.vboxdrv ]; then
/etc/rc.d/rc.vboxdrv stop
fi
Stops the process. I have not done anything about suspend yet as I don't
usually run vbox that long, just to try out ISOs.

How to reinstall base packages after system stops working properly.
http://www.linuxquestions.org/questions/slackware-14/curent-upgrade-failed-after-glibc-solibs-so-nothing-will-run-4175582032/#post5559476
It is possible to spanner the basic libraries and/or slackpkg. Chrooting
into your installation won't help then because the tools you need within
the installation have been damaged or have depend on libraries that have
been damaged.
Solution referenced here is to boot off DVD and *not* chroot but to stay
in the installer system, and mount the partition containing the damaged
slackware to /mnt, and then mount the DVD packages directory to
somewhere like /slack
Then CD into the /slack/path/to/package/sets and run something like
# "ROOT=/mnt upgradepkg --reinstall --install-new"
for at least package sets A, AD, P and L. That should restore basic
tools to the hard drive's slackware partition. Then you can chroot into
the installed slackware and reinstall patches and packages &c. or run
slackpkg as needed.

Put 14.1 back on the X220 with XFCE4 and a 100Gb SSD. All fine. I'm
using the 'wget patches and save to folder with date' approach to the
(infrequent) updates. Just bookmark changelog and you are away.
Added most of kikinovak's microlinux builds except XFCE4 which is still
at 4.10 and for the configurations. Using OpenOffice 4.1.2 because it
does not crash and I know the bugs...

X200: Kernel 4.4.9 lasted but a few days, we hardly new thee.
Today's update brought Kernel 4.4.10 and I decided to risk using
slackpkg for the update. I used the Prompt option to check the new
config files for lvm and slackpkg (mirror and blacklist). I (K)ept the
old ones. All went fine, just had to generate a new initrd as I use LUKS
on this laptop.
# mkinitrd -c -k 4.4.10-smp -m ext4 -f ext4 -r /dev/cryptvg/root -h /dev/cryptvg/swap -C /dev/sda2 -L -l uk
Then change /etc/lilo.conf to something like this...
# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-4.4.10-smp
initrd = /boot/initrd.gz
root = /dev/cryptvg/root
label = linux4_4_10
read-only
# Linux bootable partition config ends
Then run lilo and check that you get the usual LBA error message. And
reboot.

great with the wxGTK3 widgets that must be used with maxima as a
replacement for the wxPython widgets. The lame library needed for mp3
export.
MATE GTK3 build
===============
http://www.linuxquestions.org/questions/slackware-14/call-for-testers-comparison-of-mate-1-14-mix-build-vs-fully-gtk-3-build-4175579215/
Installing the binary packages of slackware.uk just worked in the same
way as it did on April 23rd 2016 except using
http://slackware.uk/msb/testing/1.14-gtk3/
The command
upgradepkg --reinstall --install-new deps/*.txz base/*.txz extra/*.txz
removes the old packages before installing the new ones and adds the new
GTK3 bits. This GTK3 version seems a tad faster and more responsive.
Maxima computer algebra
=======================
Maxima computer algebra slackbuild on -current 64bit (14.2RC2 updated to
May 5th, no multiarch libs, just 64 bit)
Just used the 14.1 slackbuilds as follows
maxima itself as command line package (xmaxima when you read the
manuals) and works with texlive and gnuplot.
Then
wxGTK3
wxMaxima
All builds in about half an hour.

Texlive install but using only http mirrors for sources - fast guest
wifi at college blocks ftp. Current 14.2RC2 updated to yesterday. You
have to remove the tetex and tetex-docs packages from stock slackware to
install the new texlive packages over the top. Remember to blacklist in
/etc/slackpkg/blacklist to avoid re-installation and watch out for a
library that needs blacklisting as well possibly because I'm using 2014
texlive.
Used the 14.1 slackbuilds to build the Texlive 25th May 2014 version
which is fine for my needs.
http://ftp.stu.edu.tw/FreeBSD/distfiles/TeX/
Above is an http mirror somewhere in Tiwan - I'm ever so grateful for
whoever is putting this up as I can't use ftp protocol on the guest wifi
at work. I was seeing 7Mbytes/s download speeds on the big files over guest
wifi which is about 20 times faster than at home.
Slackbuilds
-----------
texlive
texi2html
libsigsegv (replaces a version in stock Slackware - might be because older)
texlive-texmf-extra
texlive-texmf-docs
The texlive slackbuild needs two source files,
texlive-20140525-source.tar.xz (I got this from the .tw mirror)
texlive-texmf-tetexish-20140525.tar.xz (This one is from an http
address)
The texlive-texmf-extra slackbuild requires a source file on an http
address
The texlive-texmf-docs slackbuild needs a huge 1Gb source file from an
http Web address.
All compile fine. May recompile with 14.2 slackbuilds on release to
avoid the library problem. I don't like over-writing stock libraries if
I can avoid it.

### Installing ms core fonts.
There is a slackbuild with more fonts than the web core ones in it but I
prefer to just grab the appropriate .rpm package and use rpm2txz then
install that.
If you do that, the fonts will end up at /usr/share/fonts/msttcorefonts
You have to copy or move the .ttf files back into /usr/share/fonts/TTF
then issue the appropriate font commands on that folder. As root
# cp /usr/share/fonts/mstt*/*.ttf /usr/share/fonts/TTF/
# mkfontscale /usr/share/fonts/TTF/
# mkfontdir /usr/share/fonts/TTF/
# fc-cache -f -v /usr/share/fonts/TTF/
Log out of MATE then log in again and you get Times New Roman in
OpenOffice
### OpenOffice works on all supported slackware versions
LibreOffice is surging ahead with the code refactoring and removal of
legacy code. The programmers contributing to LibreOffice are working
hard to replace the classes that provide functions that the host system
can provide, such as font scaling and window drawing. The upside is a
faster running package and better integration and screen font
appearance. The downside is dependencies on specific versions of
libraries supplied by the host system. The result is that you can't
install the LibreOffice supplied binaries on Slackware Current (halfbuzz
library difference). Alien Bob is providing compiled binaries for
Current. He has had to patch out a failing test in order to complete the
compilation. The video display *looks* a little unstable (windows flash
black when redrawing under some circumstances). Orbea's build script
fails on my fairly stock system and it looks like an issue with the
build environment.
OpenOffice issued by Apache Foundation (Oracle's insistance on issuing
it under a different licence) still uses the older internal systems with
the consequence that you can download the binary from OpenOffice and use
the rpm2txz script to produce a suite of packages that you can install
on Slackware Current. Works fine. Identical to the OpenOffice version
used under Windows at Work. All the familiar bugs still in place.
Reassuring.
April 23rd 2016
---------------
Replacing KDE with MATE 1.14 on slackware current (14.2 RC2)
1. Grab the testing MATE 1.14 packages from slackware.uk
Make a new directory somewhere (I used ~/Downloads/mate) and cd into that
directory locally.
I used lftp with command
$ lftp slackware.uk
Then cd'd to /msb/testing/1.14/ then ls to see the x86_64
Then I just used the lftp command
> mirror x86_64
to make a local copy of the entire set of packages. Next time, I'll try
the
> mirror -n x86_64
command so that only newer packages on the remote server are downloaded.
2. Install MATE
Once download has completed, close the lftp session and become root in
the ~/Downloads/mate/ directory and install the packages...
upgradepkg --reinstall --install-new deps/*.txz base/*.txz extra/*.txz
The extra/ folder has the pluma text editor and other stuff that will be
useful for a complete desktop.
3. Remove the kde/kdei and xfce4 package groups (optional)
using slackpkg
# slackpkg remove kde # takes kdei packages with it
# slackpkg remove xfce4 # leaves Audacious which is good news!
4. Blacklist the kde/kdei/xfce4 package groups (Optional with step 3)
Just so they don't get added back on the next upgrade, nano
/etc/slackpkg/blacklist and add these lines at the end
kde/*
kdei/*
xfce4/*
5. set inittab to run level 3 at first and reboot, then startx
You'll get a nostalgic reminder of Gnome 2 that starts very quickly and
that takes relatively little memory (something like 350Mb on 64bit with
8Gb on Thinkpad X220).
I personally like to have one panel at the bottom, and I could not
resist installing the classic-windows theme. I also had to set the
kyboard layout. Just adding UK keyboard layout resulted in MATE always
starting with US layout, irrespective of the order that the layouts
where in the keyboard settings, so I just deleted the US layout and left
the UK layout.
To install a theme, just go into Appearance, click the Install Theme
link at bottom of the window and find the .tar.gz file. Don't manually
try to unpack the theme or anything.

--------------
Back up (actually syncronise) whole sytem to a dedicated external hard
drive.
The backup can be restored to another laptop.
Make a copy of files on laptop
Plug in an ext4 formatted external hard drive and allow it to be
automounted at /run/media/keith/biglongUUID
Run following command in root window and make tea the first time (57Gb)
root@lavazza:~# rsync -aAXv \
--exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found","/home/keith/.gvfs"} /* \
/run/media/keith/biglongUUID/ --delete
When command completes the external drive has a copy of everything under
the root of the local disk.
Restoring the copy to the hard drive in (another) laptop
Boot off the Slackware DVD (or any live image) and log into root
Run fdisk /dev/sda and make a swap and root partition on the local drive
(assumed /dev/sda1 for swap and /dev/sda2 for root)
Run mkfs.ext4 /dev/sda2 on the new root partition to format that to ext4
Switch on swap on the local drive using something like
# swapon /dev/sda1 [ not sure if I did this second time ]
Attach the external hard drive that contains the copy of the files and
use dmesg to check what device name (/dev/sdb)
Mount the /dev/sda2 partition of the local hard drive somewhere like
/localdisk
Mount the /dev/sdb1 partition of the external hard drive somewhere like
/usbdisk
(Slackware DVD complains if you mount stuff in /mnt)
Copy the entire contents of external drive to the local drive using
# cp -a /usbdisk/. /localdisk/
The -a switch recursively copies folders and keeps permissions and
attributes. The trailing . ensures that dotfiles and symlinks get copied
Unmount both drives, disconnect the external drive
Summary: you have all the files needed to run Linux in the /dev/sda2
partition. Now you need to sort out fstab and lilo.conf so they can find
the huge kernel in the /boot partition and mount the root by chrooting
into the linux on /dev/sda2
# mount /dev/sda2 /mnt # as per slackware installer and docs
# mount -o bind /proc /mnt/proc
# mount -o bind /sys /mnt/sys
# mount -o bind /dev /mnt/dev
# chroot /mnt
# nano /etc/lilo.conf
On the system I've copied I had an initrd with whole drive encryption so
I just comment all that out and add the default lines below to the last
section of lilo.conf
# Linux bootable partition begins
image = /boot/vmlinuz
root = /dev/sda2
label = lifeboat
read-only
# end of entries
Then run lilo to generate a new config
# lilo
(about 3 warnings usually)
Then alter fstab to suit arrangement of partitions on /dev/sda so first
few lines look like this...
bash-4.3$ cat /etc/fstab
# Whole drive encryption with LUKS on original laptop - comment these lines out
#/dev/cryptvg/swap swap swap defaults 0 0
#/dev/cryptvg/root / ext4 defaults 1 1
# dev/sda1 /boot ext4 defaults 1 2
# Add lines below...
/dev/sda1 swap swap defaults 0 0
/dev/sda2 / ext4 defaults 1 1
# Leave the rest
Then reboot into your restored system and remove the DVD. My experiment
coped with a change in wifi card and video resolution well.
March 15th 2016
---------------
Ran into trouble with the openssh update (I think, not sure) leading to
network-manager not working and then leading to fresh install of 14.1 on
X220. I just accepted the 'overwrite' option for config files which I
suspect was part of the problem. I could stop network-manager and
install wicd but I like modem-manager for usb broadband.
Now experimenting with a local packages cache and upgrading packages
individually from /patches/packages.
Using these commands from a linuxquestions forum post...
# MIRROR="rsync://rsync.slackware.org.uk/slackware/slackware-14.1"
# DESTDIR="/srv/"
# rsync -avz --delete --delete-excluded --partial --timeout=60 --exclude='source/' --exclude='kde/' --exclude='kdei/' "$MIRROR" "$DESTDIR"
To save download from mirror on stable release, I just copied the
slackware directory from the DVD to /srv/slackware-14.1/slackware as the
contents of that directory never changes on a stable release, all
updated packages go into patches/packages.

Above shows use of upgradepkg *.t?z command within the /patches/packages
directory to only patch anything that is *newer* than the installed
packages. Might cause the same problem as just using slackpkg though.

Above two posts about another semi-automatic script solution and the
wget command I've put above. Might want to do 'big' patches or patches
with consequences for configuration, manually though.

Post above mentions the --dry-run option for upgradepkg. He uses this
command...
# ls -rt | xargs upgradepkg --dry-run> summary.txt 2> error_resumen.txt
..but does not download all the non-package files. I want to use an
exact mirror and then upgrade changed packages manually, so comparing
dates or working through the changelog. I've also subscribed to
slackware-security.

Commands to get you on wifi from command line in Debian
-------------------------------------------------------
Off the Arch wiki after some googling. Tested on Debian 'standard'

I've put Slackware64 -current Xfce4 on the X200 and I am keeping
Slackware 32bit 14.1 on the X220 with it's encrypted LVM as 'production'.
This posted from ChromiumOS as provided by neverware (oddly worrying name)
on the X61s. Very interesting. Video stack seems very clean with good font
rendition.
http://www.neverware.com/
Slackware -current: you need to compile libreoffice against halfbuzz 1.3.
The binaries from LibreOffice Web site won't run as they are compiled
against halfbuzz 1.2. You get the 'Application Error' message (segfault
on loading).

----------------
Compiled conkey on Slackware 14.1/mled from the slackbuild so I can do a
clock on the desktop. I've gone for a basic textual clock with date
underneath as the analogue ones need lua scripting.
Compilation easy - just needed to set the audacity-plugin option in the
slackbuild file to 'no' to get a compile. The relevant flags section is
as follows...
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
/configure \
--prefix=/usr \
--libdir=/usr/lib${LBIDIRSUFFIX} \
--sysconfdir=/etc \

--enable-mpd=yes \
--enable-rss=yes \
--enable-wlan=yes \
$lua_params \

I run mled/slackware with init 4, and so GUI applications like
unetbootin can't run from a terminal - you get error messages about no
protocol and unable to open display.
Workaround from
http://www.linuxquestions.org/questions/slackware-14/can't-connect-to-xserver-717518/#post4466285
$ xhost local:root
# su - -c unetbootin
and we are away...
Slackonly 14.1 has unetbootin 6.08 and p7zip dependency both in system.
They seem to work on --current.
December 29th 2015
------------------
X200 news
On a roll now: reinstalled current from an old snapshot and upgraded
through the eudev transition, still running on hugesmp. Installed the
mled packages (see below) and then built R from the 14.1 slackbuild
(worked fine, the resulting package is a healthy 32Mb and
demo("graphics") runs). Then installed RStudio desktop (version
0.99.489-i686) from the .tgz package created on 14.1 running rpm2tgz
over the .rpm package downloaded from RStudio. Just installs as mled has
the jdk already. No need for apache-ant (I suspected that was a build
time dependency for RStudio).
Not running .cleanmenu or .trim, and adjusted /etc/profile.d/lang.sh
back to C locale. Will set up an initrd for this kernel in a bit.
December 28th 2015
------------------
Fresh Slackware 14.1 install minus the kde/kdei package sets.
Installed R 3.2.2 ("Fire Safety" - where do they get the names?) from
slackonly.com all fine.
The rstudio-desktop 0.98x version when installed with dependencies
apache-ant and the 8.x jdk gives the 'pointers' error when loading. See
the discussion below...
http://www.linuxquestions.org/questions/slackware-14/rstudio-install-problem-using-sbopkg-4175545576/
So I followed the advice there and downloaded rstudio-0.99.489-i686.rpm
from the RStudio Web site and used the rpm2tgz script to produce a
Slackware package. Installing that results in RStudio not giving errors
and working fine by the look of it.
December 26th 2015
------------------
Comedy half hour with a debian Jessie install - the sources list
generator is sneaking a 'testing' line in when you select Jessie.
Aptitude hits 50 suggestions and bails at that point.
Use this sources.list
deb
http://ftp.uk.debian.org/debian jessie main
deb
http://ftp.debian.org/debian/ jessie-updates main
deb
http://security.debian.org/ jessie/updates main
for sanity preservation!
All slackwares chugging along fine...
November 29th 2015
------------------
MLED 14.1 fine on the X200 and X60, and a new Web site with HowTo's
including offline installation (basically wget the entire repo and use
the command below to install all the packages, see
http://www.microlinux.eu/faq.php#offline).
$ mkdir mled
$ cd mled
$ wget -c -r -np -nH --cut-dirs=1
http://www.microlinux.fr/microlinux/desktop-14.1-32bit/
$ su -
# cd /home/user/mled # or where ever you put it including external storage
# upgradepkg --reinstall --install-new *.t?z
Then you have to run the ./cleanmenu.sh and possibly ./trim.sh scripts
from the toolsfolder
I've experimented with a stock slackware-current with a few extra bits
from mled including inkscape (one extra library compared to 14.1) and
libreoffice (just the one huge package).
Inkscape is
atkmm-2.22.7-i486-1_microlinux.txz
cairomm-1.10.0-i486-1_microlinux.txz
glibmm-2.36.2-i486-1_microlinux.txz
gsl-1.16-i486-1_microlinux.txz
gtkmm-2.24.4-i486-1_microlinux.txz
inkscape-0.91-i486-1_microlinux.txz
libsigc++-2.2.11-i486-1_microlinux.txz
pangomm-2.34.0-i486-1_microlinux.txz
all from the microlinux 14.1 32 bit repository. I saved the packages
above to a folder in Downloads, then ran the following command in that
folder as root...
# upgradepkg --reinstall --install-new *.t?z
The result is Inkscape 0.91.

Switch on sub-pixel rendering using the cleartype patch for freetype
http://www.linuxquestions.org/questions/slackware-14/how-to-optimize-fonts-in-slackware-640468/page29.html#post5067546
Rebuild freetype base package in Slackware 14.1 to incorporate the
cleartype patch that switches on sub-pixel rendering.
I just downloaded the slackware source for the freetype package from
http://slackware.org.uk/slackware/slackware-14.1/source/l/freetype/
and then issued the commands below from a root terminal in my
slackbuilds directory...
# cd /home/keith/slackbuilds/cleartype
# ls
# patch -p1 < freetype_cleartype.diff
(a couple of messages about cleartype.diff file and slackbuild script being patched)
# ls
# chmod +x freetype.SlackBuild
# ./freetype.SlackBuild
Takes a minute or so
# cp /tmp/freetype-2.5.0.1-i486-1.txz freetype-2.5.0.1-i486-1.txz
I always copy the packages to my slackbuild directory
# ls
The rebuilt package has the same name as the original freetype so will
need to blacklist it...
The patch file starts under the double row of stars and ends after the
next double row. Save as freetype_cleartype.diff

November 15th 2015
------------------
Updates for X60 with Slackware 14.1 from Nov 6th. Firefox-esr and
Seamonkey as usual. No install-new packages as expected.
Change permissions on Web pages recursively...
sudo find /var/www -type d -print0 | xargs -0 chmod 711
sudo find /var/www -type f -print0 | xargs -0 chmod 644
To upload a whole directory using sftp, you have to create the target
directory first then use the put command...
sftp> mkdir mypages
sftp> put -r /home/keith/Documents/mypages
http://askubuntu.com/questions/30629/how-can-i-recursively-change-the-permissions-of-files-and-directories
November 14th 2015
------------------
Clonezillad the test machine then installed Slackware current and
microlinux 14.2 on top of old partitions. Would not run the slackpkg
upgrade and slackpkg install microlinux-desktop commands so wgetted the
packages and installed those. Used netconfig to set networkmanager to
run network and changed /etc/inittab to run level 4. Mostly works.
nm-applet complains about permissions (needs to run as root, seeing user
so far).
November 13th 2015
------------------
Successful install of microlinux 14.1 on X61s test machine. Runs like a
champ in 512Mb with one core switched off and a spinning rust hard
drive. A few MD5 errors on download of packages so I just used wget on
the address of the package given by slackpkg and then used installpkg.
Once installed, edit /etc/inittab and change run level to 4 and run
netconfig and select Use Network Manager option (last on list). Then
reboot into the graphical log-in. Language currently set in
/etc/profile.d/lang.sh as
export LANG=en_EN.utf8
Will try the procedure with microlinux 14.2 on Slackware current
manyana.
Firefox bogs down with advert heavy Web sites, so used the hosts file at
http://winhelp2002.mvps.org/hosts.txt
and added these to /etc/hosts below the loopback entry. Wonderful.
November 10th 2015
------------------
Installed Slackware current on X61s for testing as we get near release.
Used the snapshot DVD dated 6th Nov 2015 from
http://taper.alienbase.nl/mirrors/slackware/slackware-current-iso/
Used fdisk to partition (apparently cfdisk does not work to block
boundaries automatically) and did an install in /dev/sda2 with swap in
/dev/sda1.
Then updated and attempted to install microlinux desktop using the
migration instructions. Github was asking for a user name for a bit and
slackpkg is disclaiming all knowledge of microlinux-desktop when
pointing at the 14.2-32bit repository on microlinux.fr. Also md5 errors
on extras. I imagine there is a lot of updating going on so I'll try
another time.
I just wgetted the directory with all the packages in and then used
installpkg to install the lot! Works fine but will make upgrading with
slackpkg impossible.
Clean install and try again later in Week.
November 8th 2015
-----------------
R and RStudio on Slackware 14.1 with the MLED desktop
apache-ant-1.8.2-noarch-1alien.tgz (not needed)
R-3.1.1-i486-1_SBo.tgz
rstudio-desktop-0.98.501-i486-5_slack.txz
Versions of R later than about 3.1.x when used with versions of RStudio
later than around 0.98.7x give an error about comparisons within RStudio
- comparisons limited to atomic and list types. Avoid this by using
these versions of the packages. apache-ant is listed as a dependency for
RStudio but it is a run-time dependency. Not needed when you install the
packages on another computer from the one you build these on.
Printing on the Samsung ML-1640
Install the splix printer driver slackbuild along with the optional
jbigkit. Package names are
splix-2.0.0-i486-2_SBo.tgz
jbigkit-2.1-i486-1_SBo.tgz
The splix driver must be the -2 version and it looks like you need the
jbigkit dependency as well.
Then on microlinux/MLED install as below 7th Nov, start the CUPS daemon
as usual on slackware by setting its rc.d script executable and running
the script
# chmod +x /etc/rc.d/rc.cups
# /etc/rc.d/rc.cups start
Plug the USB printer in. The MLED desktop has the xfce4 printers
configuration widget so just search for printers in the whiskermenu or
find Manage Printer in the Settings menu. The Manage Printer widget will
pick up the printer and will find the appropriate pd file for it.
November 7th 2015
-----------------
Fresh install of Slackware 14.1 on X200 with whole drive encryption.
http://slackware.org.uk/slackware/slackware-14.1/README_CRYPT.TXT
and
http://blog.darknedgy.net/technology/2014/07/27/1/
Latter helpful for screen shots and for recovery commands if something
goes wrong (boot off installer, attempt to open the Luks container and
activate the volumes and then chroot into the installation)
Commands used on 32-bit with SATA hard drive identified as /dev/sda
Boot installer, select uk as keyboard and log in as root
# cfdisk /dev/sda # Created /dev/sda1 about 200Mb and rest on /dev/sda2 both as physical partitions
# cryptsetup -s 256 -y luksFormat /dev/sda2 # Specified the key phrase and retyped it
# cryptsetup luksOpen /dev/sda2 sluks # Asked to type the key phrase, opens the 'block device' sluks for writing
# pvcreate /dev/mapper/sluks # 'physical' volume created in the block device - success message
# vgcreate cryptvg /dev/mapper/sluks # LVM group named cryptvg created - success message
# lvcreate -L 20G -n root cryptvg # 15G partition for what will be /root
# lvcreate -L 80G -n home cryptvg # what will become /home
# lvcreate -L 4G -n swap # what will become /swap
# vgscan --mknodes # writes the inodes to the 'block device'
# vgchange -ay # activates (-a) all (-y) the volumes created by lvcreate
# mkswap /dev/cryptvg/swap # makes swap space available will format
Now run the Slackware installer script 'setup'
# setup
Select keyboard
Finds the swap volume
Loads an ncurses screen that lets you choose the /root partition.
You choose /dev/cryptvg/root then format it to ext4
Installer shows other partitions found so you
choose /dev/sda1 format it to ext4 and then map it to /boot
choose /dev/cryptvg/home format it to ext4 and map it to /home
Don't touch the /dev/mapper/* entries!
Install LILO stage: choose expert mode
Then the MBR option and select /dev/sda as the device then keep selecting options (defaults!) until you get to the Begin
Linux: Add a linux partition screen you select /dev/cryptvg/root and give it a one word label like 'linux'
Install lilo
Do the rest of the install options: I just mostly go with defaults and
install all the package sets. EXIT the installer (the DVD will eject)
then select the return to root prompt. The installer leaves the
partitions you installed to mounted at /mnt/root, /mnt/boot, /mnt/home
# chroot /mnt # chroot into your installation
# mkinitrd -c -k 3.10.17-smp -m ext4 -f ext4 -r /dev/cryptvg/root -h /dev/cryptvg/swap -C /dev/sda2 -L -l uk
# # above command makes an initrd with drivers for hibernate to disk, the file system in use and the uk keyboard layout
# pico -w /etc/lilo.conf
Should look something like this at the end
# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-3.10.17-smp
initrd = /boot/initrd.gz
root = /dev/cryptvg/root
label = Generic
read-only # Partitions should be mounted read-only for checking
# Linux bootable partition config ends
You also need to change the 'append' line further up for hibernate to
disk so it looks like this
# Append any additional kernel parameters:
append= "vt.default_utf8=0 resume=/dev/cryptvg/swap"
Then save changes and run the lilo command
# lilo
You will get a few warnings about video modes &c
Use the three finger salute to reboot into the new installation as the
'reboot' command itself does not seem to work at this stage.
Emergencies...
Boot of the installer to get a working kernel and
# cryptsetup luksOpen /dev/sda2 sluks # will ask for pass phrase
# vgscan --mknodes # sets up the inodes
# vgchange -ay # finds the volumes
# lvscan # finds all the logical volumes and gives you their names
# mount /dev/cryptvg/root /mnt # mount the slackware root into mnt
# mount /dev/cryptvg/home /mnt/home
# mount /dev/sda1 /mnt/boot
# mount -o bind /proc /mnt/proc # imposes the running kernel's gunge at /mnt/proc
# mount -o bind /sys /mnt/sys
# mount -o bind /dev /mnt/dev # makes the device nodes available at /dev/*
# chroot /mnt # changes root to the local slackware
Now you can investigate lilo.conf and such and make new initrd's if
needed. Or mount an external hard drive and back up your (plain text
now) data!
To get network access going you could jack into a wired network and
# netconfig # dialogue appears just go for dhclient
# /etc/rc.d/rc.inet1 eth0_start # starts networking on eth0
The dhclient should kick in. Once stuff fixed, just comment out every
live entry in /etc/rc.d/rc.inet1.conf file so network-manager/Wicd start
on restart. You might have to change permissions on the rc scripts...

kikinovak on linuxquestions does this refit ontop of slackware with a
full xfce4 desktop. I pinched the inkscape 0.91 build, which involved
downloading and installing these packages...
atkmm-2.22.7-i486-1_microlinux.txz
cairomm-1.10.0-i486-1_microlinux.txz
glibmm-2.36.2-i486-1_microlinux.txz
gsl-1.16-i486-1_microlinux.txz
gtkmm-2.24.4-i486-1_microlinux.txz
inkscape-0.91-i486-1_microlinux.txz
libsigc++-2.2.11-i486-1_microlinux.txz
pangomm-2.34.0-i486-1_microlinux.txz
ChangeLog showed some security updates so did the upgrade today. Had to
pin my ancient GIMP 2.4 install to prevent it being upgraded to 2.8.6 as
would be reasonable for most people. Just added this pattern
gimp-2.8.6
to /etc/slackpkg/blacklist

Above works with Squeeze, Wheezy and Jessie, therefore gNewSense 3 and 4
September 23rd 2015
-------------------
Upgrade to Firefox. Slackpkg wanted to upgrade exiv as well. Allowing
the exiv upgrade broke Shotwell, as it was expecting libexiv2.so.10 but
Slackware 14.1 has libexiv2.so.12. I just had to recompile the libgexiv2
library against the new libexiv2 and then recompile the Shotwell
executable itself against the new libexiv2. I decided to do the
# slackpkg clean-system
to dump all the old 13.37 and 14.0 slackbuilds and reinstall one by one.
I somehow acquired both libexiv2.so.12 and libexiv2.so.10 so the
clean-system command took the install back to single versions.
OpenOffice reinstalled fine. Adobe 9.5.5 was ok and Shotwell runs fine
without errors. I'll see how Audacity goes in a bit.
September 20th 2015
-------------------
Slackbuilds for 14.1: Xarchiver, Shotwell, Hugin
xrchiver and thunar-archive-plugin fine and took a minute.
Works the moment you install the packages and reload thunar.
Shotwell: the old 13.37 slackbuild I donwloaded from slacky isn't happy
with current library versions so recompiling using slackbuilds using
following schema...
Shotwell (10 mins)
json-glib (1 min)
libunique (1 min)
webkitgtk3 (4 hours)
gst1-plugins-base (seconds)
gstreamer1 (minutes)
libwebp (seconds)
libgee (minutes)
vala (minutes)
LibRaw (minute)
rest (minute)
libgexiv2 (minute)
I run the slackbuilds depth first so gstreamer1 | gst1-plugins-base |
webkitgtk (all four hours of it!) then the other libraries with
dependencies then the top level libraries and last of all Shotwell
itself. I extract all the slackbuilds in a folder, drag the source code
archives into each, then chmod +x and run each slackbuild in turn from a
root terminal. After each package builds in /tmp, I copy it back into
the slackbuild folder and install it so that I don't need to keep track
of build or runtime dependencies, they will all be in place. The whole
tree can get tarred up for future use.
Hugin;
hugin (about 45 min)
tclap (minutes)
exiftool (3 minutes)
wxPython (using slacky build)
libpano13 (less than 15 mins)
enblend-enfuse (20 minutes)
gsl (minutes)
vigra (minute)
Using the slacky build of the same version of wxPython to save time.
September 19th 2015
-------------------
http://www.linuxquestions.org/questions/slackware-14/upgrading-via-slackpkg-4175483892/
Using these commands to upgrade the distribution from 14.0 to 14.1 Will
save downloads compared to the UPGRADE.TXT procedure. Will need to
regenerate the initrd and modify the lilo.conf file as per last time.
Need to check the hints file for any dodgy packages.
Commands as root...
Edit mirrors file.
slackpkg update
slackpkg upgrade slackpkg
slackpkg update
slackpkg install-new
slackpkg upgrade-all
(slackpkg clean-system)
The clean-system command will try to remove all the slackbuilds so may
decide to risk not running it. I will run the commands in a tty session
I think.
Commands work fine if you have a reliable internet connection. Not so
good if the slackpkg upgrade-all command gets interrupted and you can't
reconnect. The usual ifconfig commands failed to work. I was running a
different kernel to the one that had been installed(!) as the internet
connection was lost around openssl package (packages upgraded in
alphabetical order of name I think). So I booted off a live iso and
chrooted into the slackware partition and modified lilo.conf and ran
lilo. Error about detecting graphics hardware from within the live
session, so rebooted and re-ran lilo from slackware. Then resumed
upgrade. Completed, but X refusing to start. Ran slackpkg update found
more updates within the 14.1 release, running those resulted in X
running.
You get asked about config files. I elected to (O)verwrite all with new
configs as I don't have tweaked rc files or anything. Running on Huge
kernel 3.10.x at present, need to redo the initrd. The (O)verwrite
option overwrites the lot, including slackpkg backlist and mirrors
config. I reran the
# slackpkg blacklist kde kdei freetype-2.5.5
command to ensure I didn't end up dragging down the KDE desktop or
clobbering my pixel sub-rendering.
September 17th 2015
-------------------
ChangeLog shows a certificates update to Slackware 14.0 so decided to
set up blacklist properly to be able to update using slackpkg.
I didn't install the kde and kdei package sets as I don't use KDE...
# slackpkg blacklist kde kdei
then accept the whole list. This writes a list of all the kde / kdei
packages into /etc/slackpkg/blacklist
I use a patched freetype from slackbuilds to enable sub-pixel rendering
so I need to manually add a line to /etc/slackpkg/blacklist that
prevents a slackbuild upgrade command overwriting that one package. I
used this patterin in the blacklist file...
freetype-2.5.5
Now issuing
# slackpkg update
Then
# slackpkg install-new
# slackpkg update-all
produces no output, so all up to date and packages blacklisted.
Satisfyingly uncomplicated.
August 29th 2015
----------------
Since upgrading to Slackware 14.0 the location that Thunar mounts
external drives has changed so the rsync command to copy the hard drive
to the external hard drive is now...
rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /run/media/keith/long-UUID/
UUIDs have started to be used to identify external drives rather than
the label ('disk').
I swapped the external drive into the X200 and tried to boot but got the
L 99 99 99 99... message that indicates that the bootloader can't find
the kernel. So, booted off a live image (Void Linux happened to be
handy!) and did a chroot along the lines here...
http://superuser.com/questions/111152/whats-the-proper-way-to-prepare-chroot-to-recover-a-broken-linux-installation
http://docs.slackware.com/howtos:slackware_admin:how_to_chroot_from_media
From a terminal in Void (Void uses sudo just use su - if you are using
(say) a Debian live CD)...
1. Make sure that the hard drive in the machine is unmounted
2. My / is at /dev/sda2 (swap is at /dev/sda1) so I mount that...
sudo mount /dev/sda2 /mnt
3. Then I mount the various system directories as follows
sudo mount -o bind /dev /mnt/dev
sudo mount -o bind /proc /mnt/proc
sudo mount -o bind /sys /mnt/sys
4. Then I chrooted into the system on the disk
sudo chroot /mnt /bin/bash
The bash prompt will change to the familiar unsourced Slackware root
prompt, and now you are issuing commands from your Slackware install but
running the kernel provided by the live CD. Neat trick! Takes a couple
of seconds.
5. All I needed to do was configure Lilo
# lilo
Some warnings about not being able to detect the graphics card running
probably because the config files are different to Void. My two kernels
(generic and huge) 'added'.
6. Come out of the Slackware prompt (undoing step 4)
# exit
Prompt should come back to Void
7. Now just unmount all the mounts in the reverse order...
sudo umount /mnt/{proc,sys,dev}
sudo umount /mnt
Any errors about /mnt being busy means that something has not unmounted
or something is still running (unlikely)
Now you can reboot into the copied Slackware or carry on with the live
session.
Looking at Void Linux for the x200.
----------------------------------
Downloaded the Live image with xfce4. Less than a CD-ROMs worth.
Default repos in Europe.
Commands for checking libreoffice and then installing what you need to
run my 3g modem
Comes with xfce version 4.12 so added whiskermenu
Very few fonts out of the box.
sudo xbps-install -S htop
sudo xbps-install -S nano [ yes, I know... ]
sudo xbps-install -S libreoffice
xbps-query -R -s libre* [ shows a good range of bits and language packs]
sudo xbps-install -S alsa-utils
alsamixer [ had to unmute the main output ]
sudo xbps-install -S audacious audacious-plugins
sudo xbps-install -S xfce4-whiskermenu-plugin
sudo xbps-install -S usb-modeswitch usbutils
Install guide from base system and the underlying logic described at
http://www.cupoflinux.com/SBB/index.php?topic=2300.0
Looks to be close to a BSD base + ports/packages model.
23rd/24th August 2015
---------------------
$ wget -r -nH --exclude-directories=/slackware/slackware-14.0/slackware/kde* --cut-dirs=4 -nc
ftp://ftp.slackware.org.uk//slackware/slackware-14.0/slackware
Command above pulls down the packages from Slackware 14.0 ready for
doing an upgrade off the hard drive. Saves about a gig of download as I
don't use the KDE desktop.
-r is recursive downloading of contents of folders
-nH option means directories not prefixed by path from root of ftp server
--exclude-directories= needs full path to miss out kde and kdei
--cut-dirs=4 means that the path from root of ftp server is cut off
-nc is no-clobber so won't overwrite already downloaded files if interrupted
No user or password needed for anonymous download. Full path to target
directory needed
I need the /kernels and /extras/Wicd and Java from extras as well I suspect.

# installpkg freetype-2.5.5-i486-1_slack13.37.txz

$ freetype-config --ftversion
I'm getting 2.5.5 as opposed to 2.4.4

Made an initrd and booting from generic kernel as option at boot.
As per instructions on the 13.37 DVD. Commands below...
# cd /boot
# mkinitrd -c -k 2.6.37.6-smp -m ext4 -f ext4 -r /dev/sda2
Then
# nano /etc/lilo.conf
and added a second entry for generic kernel
# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
# Append any additional kernel parameters:
append=" vt.default_utf8=0"
boot = /dev/sda
lba32
.. loads of stuff about vesa framebuffers ......
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz-huge-smp-2.6.37.6-smp
root = /dev/sda2
label = Linux
read-only
# Linux bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-2.6.37.6-smp
initrd = /boot/initrd.gz
root = /dev/sda2
label = generic
read-only
# Linux bootable partition config ends
Then reconfigure lilo with the 'lilo' command
# lilo
Looks like entries go in order of their appearence in the file.
More recent kernel coming up...
Note: Needed to add the lba32 line when I decided not to use the symlink
to vmlinuz. Lilo gave a warning.
Can't see any obvious difference between huge and generic to be honest.
6th August 2015
---------------
Swapping an 80Gb hard drive for a 64Gb ssd. 80Gb drive has just two
partitions, swap and root, root formatted as ext4. Just a normal BIOS
based X60 laptop and MS-DOS style partition tables in the drives. No GPT
or LVM stuff.
My steps...
1) Booted off live CD, turned swap off (# swapoff -a) and used Gparted
to shink the root partition so the total was slightly less than the
capacity of the ssd.
2) Powered down and swapped the drives over so the (blank) ssd is in the
laptop and the 80Gb hard drive is in the USB caddy.
3) Booted into the live CD again and used fdisk -l to check the hard
drive locations.
# fdisk -l
On my X60, the ssd was /dev/sda and the drive in the USB caddy was
/dev/sdb
4) Used the dd command below as root to do a binary copy of the hard
drive to the ssd
# dd if=/dev/sdb of=/dev/sda bs=4096 conv=sync,noerror
The conv=sync,noerror option will ignore any bad blocks on the drive in
the USB caddy and fill them in with zeros. You don't want to many bad
blocks anyway! There appears to be a lot of differing opinions on the
block size value to use. Arch Wiki goes for bs same size as the block
size on the hard drives. Others go as high as 4M. I've compromised. Copy
takes about 1 hour at roughly 30Mb/s.
5) Used another terminal to issue the command below (user will do)
$ watch -n60 'sudo kill -USR1 $(pgrep ^dd)'
dd will then spit out a progress report every 60 seconds in the root
terminal. Because the hard drive was larger than the ssd, the copy
operation finished like this...
63422849024 bytes (63 GB) copied, 2062.75 s, 30.7 MB/s
dd: writing `/dev/sda': No space left on device
15630679+0 records in
15630678+0 records out
64023257088 bytes (64 GB) copied, 2083.22 s, 30.7 MB/s
6) Unmount the hard drive in the USB caddy and shut down. Then remove
the live CD and reboot into your smaller faster OS.
This works I think because your *filing system* and all its partitions
are intact even though you ran out of space on the SSD - the last bit
was empty.
7) You can do a read/write (non-destructive) bad block test on the hard
drive in the USB caddy using the command below...
# badblocks -nsv /dev/sdb
Google this command first! the -n option sets up a non-destructive test.
Otherwise, badblocks just writes to each block on the drive and wipes
it. Takes about 4 hours on an X60 with an 80Gb drive.
8) The 80Gb drive is now mounted in an external case. I use the
following command from the running system to synchronise the 80Gb drive
with the ssd. As root...
# rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} --delete /* /media/disk
Command line above should be all on one line! It gets justified when I
forget to start nano with the --nowrap option.
Works a treat. All the dot files (and the endless mozilla cache files -
might put an exclude in for them). The braces command is for bash or zsh
shell. See Arch Wiki

Used
dd if=/dev/zero of=/dev/sdb bs=512 count=30000
where /dev/sdb was a 16Gb USB stick with a Debian live isohybrid
image written to it using dd. Tried the commands at
http://www.cyberciti.biz/faq/linux-clearing-out-master-boot-record-dd-command/
but the command
dd if=/dev/zero of=/dev/sdc bs=512 count=1
did not write over enough of whatever the original dd put on the mbr.
I just guessed 30000, resulting in writing 15Mb of zeros to the
beginning of the USB stick.
Once blanked, I was able to use gparted to make an msdos partition
table and create a FAT32 partition.
A reference...
"One other important thing. Now that you've dd'd your stick with an
isohybrid image, if you want to use it for anything else, you'll need
to zero the first 2MB of the stick. Maybe twice. And maybe more than
2MB. I've had inconsistent results with that."

Dell: Using a cheap external USB audio card (Griffin iMic) to improve
playback quality (it does). All works except when suspending. Amarok
crashes on waking up and other music players report errors.
It looks as if alsa can't find the iMic device when waking up from a
suspend. Leaving the ncurses alsamixer running in a terminal through a
suspend gives an error about sound card being unplugged on resume (plus
a quote from the Jabberwocky of all things).
Discretion is better part of valour so I have reverted to internal
sound card. Had to delete a KDE config so iMic was forgotten by KDE
settings, and had to reboot so Amarok could find new settings.

"The general job control commands in Linux are:
jobs - list the current jobs
fg - resume the job that's next in the queue
fg %[number] - resume job [number]
bg - Push the next job in the queue into the background
bg %[number] - Push the job [number] into the background
kill %[number] - Kill the job numbered [number]
kill -[signal] %[number] - Send the signal [signal] to job number
[number]
disown %[number] - disown the process(no more terminal will be
owner), so command will be alive even after closing the terminal.
That's pretty much all of them. Note the % infront of the job number in
the commands - this is what tells kill you're talking about jobs and
not processes."

the old gst-plugins-bad package and install the new one. See...

queues
The git clone copies a set of tag files or queue files with file extension
sqf. The tag file for a package contains a list of the dependencies for
the package in reverse order so the base of the dependency tree comes
first. The package itself is listed last. The (corrected) tag file for
hugin is
libxmi
vigra
gsl
enblend-enfuse
exiftool
libpano13
tclap
wxPython
hugin
Running the ncurses sbopkg; you can load the tagfile ('manage the
queue/Load a saved queue') and then install the packages from Slackbuild
using the 'Process the current queue' command. As wxPython is already
installed (Audacity) I unticked that package at the 'Load a Saved Queue'
stage.
Sbopkg can also find *updates* to the Slackbuilds currently installed.

I'm sticking with 4.2.5 Libreoffice, but I might recompile webkit to see
if replacing that library impacts on RStudio at all.
Hugin built fine, but the queue file hugin.sqf left out a couple of
dependencies for emblend-enfuse (vigra and gsl, Visual Graphics library
and Gnu Scientific Library). Once those were added it built fine. The
largest bit was hugin itself, then enfuse-emblend.
KDE Panorama (Kipi plug in, possibly arrived with DigiKam) recognises
emblend-enfuse and libpano13, so could possibly have skipped hugin itself.

Eclipse 4.4 from slackbuilds
----------------------------
Dependencies look like this...
Eclipse
JDK
Webkitgtk
libweb
gst1-plugin-base
gstreamer1
orc
So build/installpkg order is this...
1) Orc
2) gstreamer1 - *don't* remove default gstreamer
3) gst1-plugin-base
4) libwebp
5) webkitgtk [ takes *hours* on the X60 ]
6) JDK current (1.7.0.65 from Slackbuild already)
7) eclipse (all 200Mb of it, just jar files so copying, takes seconds)
To get Eclipse to use GTK2 themes so buttons look OK under KDE, you need
to add a line that says
--launcher.GTK_version
2
under the openFile line. The '2' (argument of the variable) is on a new
line!
to the /opt/eclipse/eclipse.ini file
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library

256m
--launcher.defaultAction
openFile
--launcher.GTK_version
2
--launcher.appendVmargs
-vmargs

You can test the GTK2 theme setting by using
export SWT_GTK3=0
from bash then invoking eclipse before modifying the ini file.

Java
----
Just use the JDK slackbuild. Readme says
"This is a SlackBuild that will repackage Oracle Java into a package that
can be easily installed, upgraded, or removed using Slackware's native
package management tools. This will also package JRE so you will not need
a separate JRE build. You must Agree to Oracle's download agreement before
this can be downloaded. This means you have to use a web browser to
download it. Sorry wget folks. The mozilla plugin is no longer activated
by default."
Not compiled from source, just copies binaries out of Oracle into a
Slackware package format.
You have to log out and log in again so /etc/profile.d/jdk.sh runs so
that the $JAVA_HOME variable is exported, cat jdk.sh to see. If you
don't do that, the command java -version will return command unknown
and eclipse will complain about not finding a java version when
starting up.
You can use the 'source' command...
#. /etc/profile.d/openjdk.sh

Wine 1.6.1
----------
Wine
fontforge
freetype 2.10
cidmaps

fontforge needs the source for a specific version of freetype and cidmaps
in the slackbuild directory when slackbuilding, so these source files are
'co-requisites' I imagine.
SBo packages install fine on the Dell, so portable, and no need to
installpkg freetype or cidmaps.
Webcore fonts

Just slackbuild and installpkg
Add following to /etc/fonts/local.conf
<!-- Globally use embedded bitmaps in fonts like Calibri? -->
<match target="font" >

RStudio and R

Slackbuild of RStudio
---------------------
RStudio
R (easy one file)
apache-ant (another slackbuild)
core-dictionaries (code in with this slackbuild)
gin (code in with this slackbuild)
gwt (code in with this slackbuild)
junit (code in with this slackbuild)
mathjax (code in with this slackbuild)
Needs apache-ant as prerequisite.
You need the five source files from author's amazon storage plus the
RStudio code from the RStudio GIT repository for the slackbuild script!
GWT is huge, so will take ages to build, unless it just unpacks the needed
jar files (suspect it might). It seems to be a java app and have something
to do with ajax so I suspect this is RStudio server related.
Become root as
su -
and not just
su
This makes sure the /etc/profile.d/jdk.sh script gets run and that the
system variable $JAVA_HOME is correctly populated. The GWT thing refuses
to run if it can't find the java run time.
I'm not sure if a clean Slackware has Java, perhaps an old one.
GWT is some cross-platform build tool that makes the boost objects for the
GUI for RStudio. The final product runs fine when installed.
R itself
--------
Easy, just one file, takes about 15 minutes to compile from source
Play DVDs on KDE's native Dragon Player
---------------------------------------
Two slackbuilds needed
libdvdcss
libdvdnav
Then use System Settings | Multimedia | Phonon | Backend tab and set Xine
as the prefered backend at top of the list
Log out/Log into KDE and pop a DVD into the player. One of the actions
will be Open with Video Player (Dragon Player). Menus all work &c.
Audacity
--------
audacity
lame
wxPython
Install the wxPython package first, then lame then audacity. wxPython
takes an hour or so to compile on the X60 and raises the temperature! I
didn't use any of the optional dependencies for wxPython.
Can't get Audacity to find internal microphone on the X60 or Dell.
Microphone works as will howl back when volume turned up in 'capture' but
won't act as input. Might be KDE/Phonon thing.
Amarok does not play mp3 out of box
-----------------------------------
In a couple of years the US mp3 patents will expire and we won't have to
do this little dance.
Install gst-plugins-ugly from slackbuilds.org
http://wiki.linuxquestions.org/wiki/Slackware-FAQ
Useful page from the linuxquestions.org site. Slackware forum on there is
main channel for support.
Libreoffice
-----------
A 'binary' slackbuild, so just repackaging the binary distribution from
libreoffice.org. 4.5.2 is fine for me (pivot tables and conditional
formatting in Calc)
mv /opt/libreoffice4.2/program/libvclplug_kdelo.so{,.orig}
mv /opt/libreoffice4.2/program/libkdebe1lo.so{,.orig}
These mysterious commands have something to do with getting LibreOffice to
look ok. I think they *disable* KDE integration provided by LO so that the
gtk2-oxygen engine can provide it. I'm making that bit up. It works on the
Dell.
I think I did the symlink .gtkrc-3.0 to
/usr/share/themes/oxygen-gtk/gtk-3.0 thing on the X60.
Using xwmconfig to start in XFCE4 once seems to help as well. You get all
the usual folders set up then. There is something about setup.ini in
/etc/skel on some Google results but /etc/skel directory is empty on X60.
Slackbuilds
-----------
Compiling from source uses /tmp and puts the final packages in /tmp with
SBo extensions. I copy packages back to slack-stuff folder on X60 and if
they are OK I install them on the Dell.
X60 using networkmanager and did not configure network during install
---------------------------------------------------------------------
I didn't config networks on X60 installation because I was going to use
network manager to manage the networks including wired.
Google tells you to change /etc/hosts and /etc/HOSTNAME &c. Doesn't work
on Slackware. NetworkManager.conf overrides these settings (makes sense
when you think about it)
moka ~ $ cat /etc/NetworkManager/NetworkManager.conf
# /etc/NetworkManager/NetworkManager.conf
#
# See NetworkManager.conf(5) for more information on this file
[main]
plugins=keyfile
dhcp=dhcpcd
[keyfile]
hostname=moka
X60, X61s, Dell
---------------
Thinkpad X60 iwlwifi firmware found. Everything works. Thinkfan
available
as a slackbuild and works but running without it at present.
Make /etc/modprobe.d/thinkpad_acpi.conf with one line
options thinkpad_acpi fan_control=1
Thinkfan needs a permissions change on /etc/rc.d/rc.thinkfan then
/etc/rc.d/rc.thinkfan start
Dell E5420 i5 with an Atheros Ath9k wifi card fitted previously: All
works
oxygen-gtk firefox looks funny
------------------------------
There was something to do about getting Firefox and LibreOffice to look
integrated and not 'slabby'. It was renaming some KDE options but I have
lost the info at present (hence these notes). The gtk2-oxygen and
gtk3-oxygen packages are both installed using a default install.
Update default packages
-----------------------
Keep an eye on
ftp://ftp.osuosl.org/pub/slackware/slackware-14.1/ChangeLog.txt
No automatic updates just the ChangeLog. Each release seems to get about 5
years of support judging by older changelogs.
slackpkg provides a degree of automated updating
#nano /etc/slackpkg/mirrors
Uncomment one mirror (mirror service for me). This list is a bit out of
date so you could copy in a new mirror.
# slackpkg update gpg
# slackpkg update
Fetches a list of updates and resets database after setting a key. Then
try this lot
slackpkg update
slackpkg install-new
slackpkg upgrade-all
slackpkg clean-system
Clean system wants to remove your slackpackages so you don't actually
accept any of the choices!

http://docs.slackware.com/slackware:slackpkg
Updates for a given version of Slackware (e.g. 14.1) seem to be provided
for a number of years, usually 5. However updates depend on upstream
making updates to source. That may vary from project to project. Looks
like the slackware team isn't backporting patches in the way Redhat/Centos
do.

Installation
------------
General advice is
1) Use a live CD to partition disks before hand
2) Just have a swap and one large / (saves problems with running out of
space on /). Example: after compiling Eclipse + webkitgtk and a few other
slackbuilds I have 3.5Gb in the /tmp folder which is in / by default.
3) Install the lot (selected by default on the slackware setup program) as
that cuts out any dependency issues when installing stuff later from
slackbuilds

"You begin by booting from the CD or DVD, and are dropped into a root
prompt. From there, if you need to format your disk you can choose between
fdisk or the slightly more user-friendly cfdisk to partition your disk.
Then you can run the Slackware setup utility, which walks through the
installation of package sets. At that point you can pick and choose
software from package sets that range from "a" for base packages (such as
the kernel, glibc, and so on) to "xap" for X applications like Firefox.
The suggested method is to simply proceed with a full install, which
should be around 5.5GB of software when all is said and done."
"At the end of the install, you're prompted to set up networking ? which is
only really useful if you have a wired connection ? the bootloader
(Slackware still opts for LILO), and set up a root password. Then you may
reboot and begin using your freshly installed Slackware system. If you
want to run KDE, Xfce, or another desktop you need to either edit the
inittab to boot to an X login, (Volkerding has not embraced Upstart as a
replacement for init, nor is it likely Slackware would take a chance on
systemd just yet) or run startx. KDE, Xfce, and other desktops are
presented with very minimal changes from upstream ? another difference
between Slackware and most modern Linux distributions."
http://lwn.net/Articles/434815/
Brockmeier's review of 13.37, still true, except the full installation is
8.5Gb now.
Quotes
------
"I try very hard with Slackware to defer to the wishes of the upstream
developers. This isn't the place to be patching in new features, or
packaging beta versions (if that can be helped). Lao Tzu said that in
order to lead, one must follow." - Patrick Volkerding
This of course means that as new packages themselves based on new
libraries and sub-systems flow through from upstream, Slackware will
reflect those changes. KDE4 transition in the past and systemd in the
future will probably come through when they need to
"I really couldn't have predicted the course of events, and the majority
of it is determined by upstream projects and the ever changing needs of
the users. So, I like to stay focused on more immediate goals. As those
are accomplished, what needs to happen next comes into focus. It's been
more a process of evolution than directed design." Volkerding

Marketing/perceptions
Recent marketing seems to be moving away from the Subgenius stuff (funny
for about 5 minutes then gets old, some of the web sites are scutty). The
'neutrality' of packaging upstream projects really shows.

Any discussion of slackware in a server context seems to come down to 1)
pam 2) systemd 3) remote admin 4)RHEL as standard (US)
Perhaps market to makers and tinkerers hardware people and hipsters as
client and small server system?
"Slackware is the shibui operating system. Shibui objects, in Japanese
aesthetics, bear a simple, unostentatious design that incorporates and
reflects the natural grain of the materials it's made out of rather than
trying to hide them; the opposite might be "flashy" or "plasticky".
Slackware is close to being the simplest possible distro, with minimal
package management and virtually no specialized tools for managing /etc
like Red Hat and Debian have; its texture reflects the natural grain of
Unix." --bitwise on Reddit
