Thanks. Your userspace is issueing MI_WAIT_SCANLINES cmds to the gpu,
which just doesn't work. Can you please upgrade xf86-video-intel to the
latest released version and check whether it works.

Generally userspace with that bug is extremely old (and if the other
things are equally outdated) rather buggy for Sandybridge. I highly
suggest updating the entire graphics stack to something modern
(Sandybridge-wise).

Yours, Daniel
