On resume from suspend on a Sony VaioPCG-V505DX , the screen briefly flashes a
very corrupt image. The corruption is temporary, lasting only a couple of
seconds or so, but it is a bad look nonetheless. Screen corruption is often
accompanied by loud beeping (bug #235686), which is an unnecessarily jarring
start to an X session.

Suspend to RAM otherwise works fine.
