Comment 16 for bug 980058

Your GPU is extremely unhappy. The fallback to vesa is because it fails even to initialise its command rings, and it looks like it falls over regularly even if it manages to get past that.

I would strongly advise you looks for a BIOS update, and please try a very recent kernel. I would also recommend drm-intel-experimental (from the kernel mainline ppa) as our detection of broken firmware has improved along with our tolerance.
