Correct password does not unlock computer

[Vadim Peretokin]

Every once in a while the lock screen will stop accepting the correct password, and I lose all my open work.

I do have two input methods installed, but toggling between them on the lock screen does not work.

I am able to go back to the main login screen and enter the password there, but then it simply takes me back to the lock screen.

Happy to add any additional information!

Maybe try right clicking on the password field and select "Show Text" to make sure it's the correct password being entered?

Right-clicking on the password field doesn't show me a menu :(

Could you try to see if you get the issue without extensions enabled? the journal log has some errors about workrave
