Description Eric McAlvin 2023-08-31 15:43:39 UTC 
This is new behavior in Leap 15.5.  It did not occur in 15.4.  

If you kill X (via Ctrl+Alt+Backspace/Backspace) when kscreenlocker_greet is running (you are presented with the unlock screen password dialogue window), it will indeed kill X and bring you back to the display manager (lightDM in my case).  

However, when attempting to log back in, xmessage pops up stating: "startkde: Could not start Plasma session".  

Prior to executing Ctrl+Alt+Backspace/Backspace, the kscreenlocker_greet process will have a parent process of 'ksmserver'.  After killing X with Ctrl+Alt+Backspace/Backspace though, the parent process becomes "systemd --user".  

It is not until I kill that kscreenlocker_greet process can I launch my new KDE Plasma session.

In Leap 15.4, Ctrl+Alt+Backspace/Backspace would successfully kill that kscreenlocker_greet process.
