Comment 11 for bug 812638

After installing the updated xserver-xorg-video-intel package found here:

https://launchpad.net/ubuntu/+source/xserver-xorg-video-intel

I haven't had any further issues (artifacts, blank screens, etc) in nearly 2 hours of use and testing. Kernel and video driver configuration follow:

12:35 PM ~ ❱ uname -r
2.6.38-8-generic
12:35 PM ~ ❱ dpkg -l xserver-xorg-video-intel | grep xserver
ii xserver-xorg-video-intel 2:2.14.0-4ubuntu7.2 X.Org X server -- Intel i8xx, i9xx display driver

I'll report back if I have any further issues. As always I'm happy to experiment if more information is needed.
