[Bug 1448312] [NEW] black screen after suspend

 

Public bug reported:

Upgraded to 15.04 yesterday, all packages upgraded.

The screen is black whenever I resume from suspend. This happens
consistently. The machine is on and responds to keyboard input, so I am
able to Crtl + Alt + F1 to a new screen, and sudo reboot from there, but
nothing is visible while I type. When I reboot, the machine starts and
runs normally.
