[Bug 1902263] Re: kscreenlocker_greet after a suspend causes a blank unusable screen

[GokulChittaranjan]

** Description changed:

+ UPDATE: I notice this problem even when I leave the system that results
+ in a screen lock - in such a case, the screen remains frozen. So the
+ screen prior to locking can be screen -- inadvertently by an unintended
+ person.
+ 
  Steps to reproduce the bug (And a workaround to keep working with it):
  
  - Suspend the system (typically the system remains suspended for > 30mins)
  - Resume by pressing any key
  - A blank screen with a mouse pointer appears
  
  To get back the unlock screen, manually switch to a terminal (e.g. Ctrl + Alt + F3) and then do
  - $ ps -Af | grep lock
  - $ kill -9 ${PID_OF_kscreenlocker_greet)
+ 
  
  Switch back to Ctrl + Alt + F1...
