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.
Can you please attach your .local/share/sddm/xorg-session.log file?
(In reply to Nicolas Fella from comment #2) > 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.
Are you trying to log into a X11 or Wayland session?
(In reply to Nicolas Fella from comment #4) > Are you trying to log into a X11 or Wayland session? X11
thanks for the information
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.
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.
