[SOLVED]KDE lost on login

Hi,

I was using kde, there were some minor problems after the video card installation, I fixed it. Now I can't see kde in the settings on the bottom right of the gdm screen.

cat /var/log/Xorg.0.log | grep EE

Re: [SOLVED]KDE lost on login

Thank you. I guess X11 is slowly moving to wayland too? Would it make more sense to use X11 or wayland for the DEs I use?

And I'm using `gdm` as a login manager so that it can work with all of them smoothly (most smoothly at least). Can you suggest a better option or is this the most robust and workable design?

Edit: It looks more like X11 and wayland are splitting. What do you suggest me to do ? Should I switch to wayland completely or install `plasma-x11-session` ? I am thinking about other DEs and in general. At the time, wayland seemed to be not very compatible, X11 was preferred because it was the general / basic server of the system like systemd. Is there any change now and is there any advantage of wayland other than being new and up to date?

Re: [SOLVED]KDE lost on login

The movement is clearly towards wayland. Plasma already said they will drop x11 completely in a future update, the split is just a preparation for that. Gnome already dropped X11 in Gnome 49.
Personally, I am using wayland on Plasma for some years now and have not had any issues. Programs that don't support wayland run with Xwayland anyway but those are getting less and less.

Re: [SOLVED]KDE lost on login

vim. The answer is, was and will clearly remain: vim. emacs is bloated and the editor component not very good.

You need to use the software stack that works for you - whether that's plasma or gnome or some standalone wm… other peoples preferences don't matter.
If you're running into problems w/ wayland, install the x11 session and file a bug upstream.

Ftr: X11 isn't moving anywhere - certainly not to wayland. Some desktop environments might (well, apparently "are")
Oh, and despite the public fuss: both gnome and kde will still run xwayland and in doubt you can force Qt and GTK to use X11

Re: [SOLVED]KDE lost on login

I guess the cleanest and most convenient method is to install the `plasma-x11-session` package? That's what I did.

Whoaw! Such update man! Now its working 1920x1080, taskbar is not on the air and stable. It looks cool SOLVED!
