I have installed kde-desktop on my Ubuntu 22.04.
When I login to the KDE session and hit ctrl+L to lock the screen, the kscreenlocker app doesn't allow me to unlock it back.
I can see that the password is correct (there is a preview password button), but it says "Unlocking failed". So I have to click on "switch user", and login using GDM. After that it unlocks my session.
How can I figure out what is wrong?
