I have recently switched to KDE Plasma and I am currently facing the following problem: When the screen is locked a black screen will be shown with the following:

The screen locker is broken and unlocking is not possible anymore.
In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F2), log in and execute the command:

loginctl unlock-sessions

Afterwards switch back to the running session (Ctrl+Alt+F8).

Although the above is a good workaround to unlock the locked session, is there any solution how this can be avoided and thus the screen can be locked successfully?

Thanks in advance.

The same issue on my PC

Any solution found ?

Can you run

/usr/lib64/libexec/kscreenlocker_greet --testing and attach the output.

no such file or directory..

I found it at

Code: Select all

/usr/lib/x86_64-linux-gnu/libexec

but it doesn't give out any useful information

Code: Select all

~$ /usr/lib/x86_64-linux-gnu/libexec/kscreenlocker_greet --testing
