Fedora kde 36 logout not functioning

when i logout of a fresh install and upgraded version of fedora kde 36 i get a blank screen when logging out. i am able to toggle tty and log back in that way. log in on fresh boot works fine as well as logging in from a lock. i have found others with this same issue since a few releases ago:

As a caution - a lot has changed in Fedora land since Fedora 32. I haven’t seen this issue on KDE in Fedora 35 or 36 personally. Next time this happens, are you able to immediately log into a vtty (hit Alt+Ctrl+F2) then run journalctl --since -5m and see if there are any obvious error messages?

when i logged out i got the black screen like always, doing Alt+Ctrl+F2 gave me back the regular login screen but it was “frozen” with the password field populated. i did Alt+Ctrl+F3 to get a shell to login and ran journalctl --since -5m. im not sure if there is a security issue in posting the output of that?

Why would you think there is a security issue there?

You can always redact the parts you personally think might be security related before posting, but the details are needed to evaluate the events.

im not familiar with all of the output so was just making sure.


I see a number of KDE-specific core dumps in there. This info might be useful as submitted to KDE developers to debug.
