  ATA Origin Inception

  Whenever the system locks after closing the laptop lid for a period of
  time and I try to resurrect the screen is frozen not on the lock
  screen but on the desktop. Eventually this transitions to the laock
  screen but still freezes. I can move the mouse the entire time.
  Eventually after a period of time I can access the password screen and
  all is normal but total duration can be 2 minutes or more. In 18.04 I
  did not have this issue.

  I have marked it as a security vulnerability as if I close my lid and
  sensitive data was visible on screen opening the lid will show this
  instead of the lock screen.
