Comment 19 for bug 1258655

I disagree. Mir shouldn't behave badly because the display driver is behaving badly. And I don't think crashing really helps anyway. Won't unity just be respawned and again try to use the display device without doing anything to fix the unrecoverable state?

If the display driver still hangs after powerd is changed to synchronize with early suspend / late resume, then we should try to fix the display driver.
