Bug#519243: use UXA to fix?

[Cade Robinson <cade.robinson@gmail.com>]

I had the same issue on a Intel 82Q35 Express.

I for a couple days now haven't had any issues by switching to use UXA
and KMS (kernel-based mode setting).
I am not sure which fixed it but I don't have corruption.

To enable UXA I put this in the Device section of xorg.conf:
Option          "AccelMethod"   "UXA"

Then to enable KMS I put this line in /etc/modules:
i915 modeset=1

I haven't had any corruption, suspend and resume works fine, and it
seems a bit faster to me.

The downside is that I can't switch to virtual terminals.
If I try it appears to lock the machine.  My desktop stays up and the
same.  The mouse disappears and any activity like blinking cursor or
scrolling stops.  But if I switch back to VT7 everything comes back.

I guess I can live with no VTs for now without having corruption.
