Hi,

At least twice this week when I woke up my system from sleep instead of lock screen I am presented with black screen and cursor. There is no way for me to get back to working system except go to tty and restart sddm or reboot system. Htop doesn't seem to show any obvious culprit. This is highly undesirable as I keep losing my unsaved work.

I encouter this as well a few times recently, seems to be related to some of the latest updates. For some reason "plasmashell" seems to crash sometimes. This can be pretty painful if krunner is crashed as well (and feels like always...). So try press "ALT+F2" and run "kquitapp plasmashell & plasmashall" or try to get into a console and launch the command there. After a few seconds the desktop shall be there as normal, even tho these crashs are extremly nasty...

Best regards,

Florian
