You have been subscribed to a public bug:
This is basically the same symptom, but from many years ago:
https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1431128
To reproduce:
1) Suspend (I do so via the dropdown menu)
2) Turn off display. (Not sure if relevant)
3) Turn on display. (Not sure if relevant, problem occurs even if this step is
after #4)
4) Wake from suspend (I do so by pressing a key on the keyboard OR the power
button)
5) Screen either stays black or flickers for a second and then goes black
6) Press any key on the keyboard
7) Login screen appears (as if it was in screen-saver/lock mode before)
I'm guessing the bug is not very reproducible because you would have
noticed it already. However, I should note that (aside from a few days
after I installed the OS) the problem happens 100% of the times I wake
from sleep
Some unique details about my setup:
1) The default 20.04 installation failed to a bug installing the packaged
Nvidia drivers, but skipping that and doing it after installation worked in all
respects that I can see
2) My computer is custom, not OEM.
3) I do have VMWare Workstation installed
4) I used to use 18.04 and 19.10, neither had the issue
