Title:
Display goes black at random times
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Frequently using Ubuntu 15.04 my display blacks out. It occurs at
seemingly random times, many times back to back.
I'm getting the following messages in syslog each time it happens.

I can restore my display by either closing my laptops lid and reopen,
or by running
