Public bug reported:

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

** Description changed:

  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
