Public bug reported:
Suspend worked fine on 13.10, but since upgrading to 14.04 I have issues.
I can suspend the laptop, either from the suspend button or closing the lid.
When opening the lid, the screen does not seem to turn on. It does not respond
to anything, and changing terminals has no effect. I have to hold the power
button in for a hard reset.
At first, it sometimes worked fine on resume. It seemed that unplugging my
wireless mouse before suspending and then plugging it back in once suspended
helped the issue, but lately that has not been working either.
