Description Andrei Borzenkov 2024-03-15 17:41:49 UTC

Snapshot 20240311, pretty much vanilla installation in VM without any third party repositories. Autologin is enabled. 

After update to Plasma6 I cannot logout from KDE session. I get confirmation dialogue, press Logout, and nothing happens. GUI does not react anymore to mouse, I can't do anything. I can switch to another vt and terminate session using e.g. "loginctl kill-session".

Attached are journalctl -b for user and system as well as sysemd-cgls output. From user journal it can be seem that logout is actually initiated but a lot of processes remain.

Under Wayland after "logout" GUI remains active, I can launch applications etc.

Though the logout greeter should either trigger logout or not, there's no in between...

What happens if you do "qdbus6 org.kde.Shutdown /Shutdown org.kde.Shutdown.logout" manually?

Logs are mostly identical - logout is initiated, something is done but session is not terminated. And I mentioned already, in X11 GUI is frozen after logout attempt. 

journalctl --user -b attached.
