+ [Impact]
+ Users of nvidia graphics drivers can see graphics freezes or corruption after
suspend/resume. Switching to a VT and back to X can potentially solve freeze
issues, but corruption may result.
+
+ [Test Case]
+ Suspend/Resume many times with nvidia graphics and see if the problem happens.
+
+ [Regression Potential]
+ This is already in Trusty.

Perform regular suspend, either from system menu or close laptop lid,
when system resuming from suspend, it will freeze.
Switch to VT and back to X can solve freeze issue,
but the screen are gabled and some character rendering are strange,
however whole system can perform usual task.
