When my computer tries to lock the screen, it fails, producing the following message:
The screen locker is broken and unlocking is not possible anymore. In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F1), log in and execute the command:
The log out of the virtual session by pressing Ctrl+D, and switch back to the running session (Ctrl+Alt+F2).
There are numerous reports of this floating around, but this one is the only one that seems to have a solution. Unfortunately, it doesn't apply to me.
I am running Fedora 36.
