Hi,

I actually started testing the latest v4.6 for another issue I was
having with screen flickers after trying to test 4.5.2. So far it seems
to be working, but I will have to continue testing since this issue
happens daily but at random times.

Title:
  Black screen after wake

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I got this issue once a day or so when I close the lid of my laptop to
  suspend, and when I try to wake it up I get a blank screen where often
  the only thing that shows up is the mouse cursor. I can't use the
  mouse nor keyboard, and I can't access virtual consoles (ctrl+alt+f1).
  I'm forced to shutdown the machine by pressing and holding the
  machine's power button.
