** Description changed:
Problem description
---
Expected behaviour:
After putting the computer to sleep (suspend), the display manager (LightDM)
appears, I log in and the session resumes.
Behaviour:
After logging back into the session the screen remains black. The system is
awake and I can get back to the display
manager, but I cannot continue work due to a black display screen.
+ [Test Case]
+ Suspend the computer, then attempt to log back in. The screen will remain
black.
+
+ [Regression potential]
+ None apparent, tested in utopic and a ppa.
