Bug description:
  [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.
