Bug Description

I'm on 20.04
When I lock the screen the login screen doesn't appear.
Instead sometimes it just flashes and doesn't lock the screen or the machine freezes and needs to be restarted.
I flagged this as security related because now as a user I can't lock my screen, so I either have to leave it unlocked or completely shut down my machine.
Thank you very much in advance!
Eduardo
