I am not sure it is related, but my Dell D810 laptop (ATI Mobility X600 w/ open source drivers) worked well until +/- last Friday (Aug. 17). Now I do have some garbage on my main display, while the external display obviously misses some drawing. It seems the drawing that doesn't go to the external display does go to the internal display but in a garbled form. I can see it very clearly when I move windows on the external screen. Note that this is a dual-head configuration.
