Kscreenlocker broken

[architectlin]

The screen locker is broken and unlocking is not possible anymore. In order to unlock switch to a virtual terminal(Ctrl+Alt+F2), login and execute the command loginctl unlock-session 2. Afterwards switch back to the running session (Ctrl+Alt+F1)

Is it Wayland-only?

Looks like this bug: https://bugs.kde.org/show_bug.cgi?id=461123.

Try to update, I just rebuild plasma-workspace package maybe it will help.

[architectlin]

unfortunately no change:(

No help but..
There are a whole bunch of these lock-screen issues and the ones that I have read about so far use Intel graphics either on wayland or X11

https://bugs.kde.org/buglist.cgi?bug_status=__open__&component=general&list_id=2212813&product=kscreenlocker

Here using nVidia, X11 it works fine with the timer or starting the locker with meta+l
What GFX do you use, it maybe worth you checking out the above buglist

[ZaWertun]

Solved it.
It's because of layer-shell-qt wasn't rebuilt after Qt update.

Here is new build: https://copr.fedorainfracloud.org/coprs/build/5047970

[ZaWertun]

@architectlin try to update now.
