Title:
  Resuming after suspend I get only black screen

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I use Dell Precision T7500 machine.
  My computer is suspended automatically.

  When I push the power button to wake up the machine, I get only black screen.
  I can't switch to another tty, probably, although I cannot confirm because of the black screen.

  If I uncheck the checkbox "Require my password when waking from suspend", then my computer
  wakes up correctly.
