Description AndrewZ 2021-11-26 23:46:01 UTC 
SUMMARY
When leaving my computer for some time, upon return the login screen on my primary monitor is completely black. The second monitor shows the login screen, but the password entry field is unresponsive. I can still type my password and successfully login, however there is no visual feedback in the entry field showing my input.

When I log in, my secondary monitors refresh rate is usually set to 60hz and sometimes the background image gets set to the default.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  Manjaro - X11 session
KDE Plasma Version:  5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2

Other info:
I have two of the same monitors running at 2560x1440 @ 144hz 100% scaling via displayport connection. My computer isn't set to suspend but the screen energy saving is turn on.

journalctl output during issue
Comment 3 Vlad Zahorodnii 2023-01-19 13:08:33 UTC 
It looks like there are multiple issues going on. The login screen: seems like some weird SDDM issue. Black screen after login sounds like plasmashell crashes and journalctl output in comment 2 confirms that. Either way we can't track multiple issues in one report. Please report login screen issues to SDDM developers (if you use SDDM), and file a bug report for plasmashell crashing.
