Bug#566781: linux-image-2.6.32-trunk-686: Suspend / Resume works correctly for the first time (Lot of thanks) - Minor issues
> Hit the 'Power' button or Ctrl-Alt-Del:
> A pop-up dialog asks me what I really want to do.
> - When I choose 'Suspend', Suspend systematically succeeds.
> - After Suspend has succeeded, when I trigger Resume by hitting
> the 'Power' button, then Resumes systematically succeeds, but
> systematically displays a black screen. I have to hit 'Shift' or move
> the mouse in order to get the 'Password' dialog displayed.

this looks more like a kernel bug,
could you report that upstream in bugzilla.kernel.org
and let us know the bug nr so that it can be tracked.
