Title:
  After Xenial upgrade display will no longer turn on when waking from
  suspend.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I was unsure what daemon actually controls suspending of a laptop when
  the lid is closed, so filed under "I don't know.". After a fresh and
  patched install of Xenial, when I open the lid to my laptop it will
  wake up from suspend, however the LCD does not turn on, as far as I
  can tell everything is actually working underneath but I need to do a
  hard restart to make the machine usable again. My laptop is a Dell
  Latitude E6440. I will gladly provide any info needed.
