I’m using Cinnamon on EndeavourOS, everything is up to date.
Since some time ago (1-3 weeks, can’t remember exactly) I cannot shut down/restart using the menu, as it logs out instead.
I can shutdown using cli no problem, but I’m used to use the menu so I would like to fix it.
There is definetely some good clues in the syslog, but I cannot decifer it. Tried to duck it, but couldn’t find anything that helped me fix the issue.
Can anyone point me in the right direction? Thank you 
Here’s the relevant part of journalctl -b 0
