[Bug 1511885] Re: Screen doesn't wake up after is automatically turned off

 

I have disabled the setting in System Settings -> Brightness and Lock ->
"Turn screen off when inactive for:" by setting it to Never. This isn't
really a solution though, just a temporary workaround. One interesting
thing to note is if I log out the screen goes to sleep after a few
minutes but it comes back on when i move the mouse or press a key on the
keyboard as you would expect.

Bug description:
  When the system puts the display to sleep after X amount of time of
  inactivity it will not turn back on. Black screen. I can press
  ctrl+alt+f1 to get me to a terminal session and that works. I then can
  restart lightdm or reboot.
