My desktop PC is used by the family and each member has an account.
Hence, it is required to log off and the log in each time another user wants to use the computer.
The thing is that after multiple logoff / login (not the same number each time but usually 2 or 3), the user login will end up with a black screen after successfully have passed the SDDM identification step.
I don’t know how to troubleshoot that. I have not found straightforward tips on the system log.
The only thing that I have noticed is, despite a user is logged off, there are still processes (like kwin_w11) running for this old user despite another user has logged in.
Hi
I read more and more on this topic and I saw black screen issue often points to X11.
However, I have not found a solution. I have not found or understood which log and information to search for…
Could anyone at least give me some hints for the troubleshooting ?
Well, just tried after modifying /etc/systemd/logind.conf as explained but it doesn’t change anything.
I still have my black screen issue and when I don’t, I still have the other processes running. It looks like setting KillUserProcesses=yes doesn’t work for me.
Yes indeed, I have done a reboot but it doesn’t help.
It is actually what I wonder. I am stating that because when I log out (after ctrl-alt-del), then alt-F2 and alt-F1, log in again, I don’t have anymore the other users’ processes running and all work fine.
