Description: | |
Long time I didn't write a "port of the week". | |
This week, I am happy to present you **sct**, a very small utility | |
software to | |
set the *color* of your screen. You can install it on OpenBSD with | |
`pkg_add | |
sct` and its usage is really simple, just run `sct $temp` where $temp | |
is the | |
temperature you want to get on your screen. | |
The default *temperature* is 6500, if you lower this value, the screen | |
will | |
change toward red, meaning your screen will appear less blue and this | |
may be | |
more comfortable for some people. The temperature you want to use | |
depend from | |
the screen and from your feeling, I have one screen which is correct at | |
5900 | |
but another old screen which turn too much red below 6200! | |
You can add `sct 5900` to your .xsession file to start it when you | |
start your | |
X11 session. | |
There is an alternative to sct whose name is *redshift*, it is more | |
complicated | |
as you need to tell it your location with latitude and longitude and, | |
as a | |
daemon, it will correct continuously your screen temperature depending | |
on the | |
time. This is possible because when you know your location on earth and | |
the | |
time, you can compute the sunrise time and dawn time. **sct** is not a | |
daemon, | |
you run it once and does not change the temperature until you call it | |
again. |
