Bug Description

Running the newest release of ubuntu (20.04LTS).

I entered my password to log in after the lock screen had engaged automatically and it accepted my password (greying out the buttons) but didn't log in.

Five minutes later it still hadn't changed so I went to another TTY and killed the gnome-terminal process. X started up again, and allowed me to log in with no issues after that.

Intentionally locking the screen did not trigger the bug.

This could be a serious problem for anyone not already familiar with linux as this would force a reboot.

I think I have a workaround, if the problem is the same as the one I'm facing. Press the user button on the bottom right where you enter your password, the lock screen changes colors , re enter the password and login will be successful.

Also if the PC went to sleep while it was idle (screen off), logging in will fail on resume.
