The problem appeared recently and I don't know how to pinpoint the cause of it. The screen will go completely black with a white underscore at the top left hand corner. This problem occurs a few times per hour.
The applications seem to still be running in the background, as I can still hear people and they can still see me if I am in a conference call. I can also login to another TTY by pressing Ctrl+Alt+F{i}, and if I restart the computer, it works just fine.
I'm running Lubuntu 18.04.6 LTS on my machine. Thanks a lot for your help!
