SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian Testing

ADDITIONAL INFORMATION

Comment 1 Pierce 2021-01-11 16:52:08 UTC

I'm able to start plasmashell and kwin from within XFCE, but for whatever reason they do not work if I try to log in to a Plasma session.

Comment 2 Nicolas Fella 2021-01-11 17:25:56 UTC

Can you please attach your .local/share/sddm/xorg-session.log file?

Comment 3 Pierce 2021-01-11 17:32:24 UTC

> Can you please attach your .local/share/sddm/xorg-session.log file?

It's completely empty. Trying to log in to Plasma didn't populate it with anything, either.

Comment 4 Nicolas Fella 2021-01-11 17:38:27 UTC

Are you trying to log into a X11 or Wayland session?

Comment 5 Pierce 2021-01-11 17:52:31 UTC

X11

Comment 6 Nicolas Fella 2021-01-11 18:08:04 UTC

thanks for the information

Comment 7 Pierce 2021-01-12 18:39:44 UTC

Created attachment 134790 [details]
excerpt from .xsession-errors

I'm dumb and forgot to check ~/.xsession-errors, so here's what happens when I tried to start a Plasma session.

Comment 8 Martin Collins 2021-01-14 18:28:32 UTC

I have the same issue. After entering my password the K banner comes down but the progress bar stalls about 2/3 way along.

I discovered by accident that Alt-F2 will open a Krunner and if I type plasmashell in it I get a desktop. It is missing some of my settings and it does not restore my session but it is usable.

Plasma is now working without issue. If you're missing effects like window transparency and shadows, open up the compositor section of System Settings and re-enable OpenGL detection, then restart kwin.
