Since very recently (a few days) I'm having trouble unlocking my lockscreen via the graphical interface. I can unlock it using a text-terminal (ctrl-alt-f2) and the command: `loginctl unlock-session 3`
Hmm, after some more investigating, it appears the problem is that now a mousemovement is required to get a password prompt. It used to be that you could just start typing the password and the lockscreen would catch it, without needing to touch the mouse first...
STEPS TO REPRODUCE
1. lock screen
2. type password
3. ... nothing
the screen remains locked
password typed is accepted and after the first keystroke, the prompt is shown with balls indicating the password is being typed.
