Xubuntu - logs out for no reason

Support and Help
1

Hello.

I use the last latest Xubuntu and sometimes it just logs out for no reason. Usually when I start another program.
Here is the log from Journalctl. I suppose there should be written why but I did not find any clue:

pc@pc:~$ journalctl --since "3 minutes ago"

Thank you for your help.

I had this issue with Kubuntu for a while, I never found out exactly what the problem was, but by curing another issue with my multimedia programmes by installing the proprietary Nvidia drivers I realised the logout issue was cured.
Hope this helps (somehow). Tony.

thank you. I will try it. It happens actually a lot when I open Thunar.
