Yeah, we've all been working on the switch to Wayland for a Long Time.
<goes off, looks around> Distrowatch doesn't have Wayland vs X11 far as
I can find in the search-for-a-distro function, but ... a list:
Fedora.
Debian.
openSUSE Tumbleweed.
PureOS.
Red Hat Enterprise Linux.
SUSE Enterprise Linux.
Also I think Mageia has switched, or lets you select it at login.
And then if you want your brain to hurt,
https://www.dz-techs.com/en/using-linux-with-wayland
https://en.wikipedia.org/wiki/Wayland_%28display_server_protocol%29
There's a good video on why Wayland is a huge design improvement (not
nearly as slow and crufty), but getting the bugs out is a different
matter. Remote desktop and nVidia support are apparently still a crapshoot.
Not this one, but it has a quick overview:

Found this:
The quickest (and fun) way to check if you are using Xorg or Wayland in
GNOME 3 using GUI. Press Alt + F2 type r and smash Enter . If it show
the error "Restart is not available on Wayland" img, sorry, you are
using Wayland. If it work as expect (restart GNOME Shell), congrats, you
are using Xorg.

Choice is good, except when there's none!!

Cuz somewhat random when it ran into the bad memory address, depending
on what crap had already used memory so it had to go there.
My old 286 has a bad RAM chip and whenever some app sucked up too much
RAM (such as changing font in WordPerfect), it would hit that bad chip
and crash. Figured out the affected address, locked it out in the DOS
memory manager, and it never crashed again. Fair trade for the 16k of
lost RAM, or whatever it was.

Oh, yeah, whole neighborhood can enjoy... <g>
I don't have anyone close enough to matter, and besides the trains go by
at all hours of the day and night, and drown out anything short of
nuclear war.

These are standard iron pipes (and one newfangled plastic pipe) that
also branch over to the the furnace and water heater, so I doubt would
need any different. There's another pipe-to-nowhere in the garage
(actually two) apparently at some point for the gas dryer, presently not
hooked up at all. But new pipe is not difficult; my sister's hubby ran
it himself to their new generator (in this case plastic, and yes they
sold him the wrong size to start with... tho we figure that can
eventually go to a small heater in the barn.)

I used to have a flashlight that you cranked to charge the batteries.
About one minute of cranking for five minutes of light. Dunno what
became of it but until the batteries got too tired, it worked quite
well. Would still work if you didn't mind continuously cranking.

Two fridges and a freezer. But the idea is not to deal with blackouts
but rather to take the more-optional stuff off the regular power bill as
much as practical.
It would take at least a couple days for my little freezer to start
seriously thawing. Five hours in summer made no difference at all.
Benefit of being packed full, cuz it's only about 7 cu-ft. And in
winter... it's a manual defrost so it sits outside, and won't warm up
unless the power is off til May. <g>

It had been mighty flat. The space under the bark was less than 1/4 inch.

Ah, I knew there was a reason...
