Those 2 comments show I think that the display-manager decided to start a new session
(like a Switch User), and that the initial session has not been terminated.
It would be interesting thus to look for the display-manager logs in the journal and also in
its dedicated logs if any.
I’m unsure of what DM KDE Plasma uses at the moment. To verify that, run:
systemctl -n 0 status display-manager
XXX.service - ...
then XXX is the name of the display-manager. Look in the journal with:
sudo journalctl -b -u XXXorsudo journalctl -1 b -1 -u XXXfor the previous boot
@gnwiii: what do you think of using fpaste to get a whole journal where the problem
occurs ?
