I'm using Ubuntu 20.04 and after waking up from suspend I get a black screen with a cursor.

I've run update and upgrade and it didn't fix the problem. I tried switching to lightdm but the problem is the same. I tried pressing ctrl + alt +f1 and ctrl + alt +f3 and nothing happens. I'm on a laptop so I've tried using fn too, but still nothing.

The only thing that seems to work is holding down the power button to stop the machine.

Apparently this was a bug in the Nvidia driver. The new version specifically fixes this problem, but it is only available on Nvidia's website as of yet.


When the black screen appears, you can press Ctrl+Alt+Scroll Lock or Ctrl+Alt+Pause/Break multiple times and then some help appears.

Also, Ctrl+Alt+B allows rebooting without pressing the power button.

I know that's not much of a help, but it is something.
