[Bug 1543613] Re: After Xenial upgrade display will no longer turn on when waking from suspend.

 

apport information

** Tags added: apport-collected

** Description changed:

  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.
