These are the package sources for the
xserver-xorg-video-intel
package
from Ubuntu 13.04 with the
"virtual CRTC" patch
applied. Just playing around...
The plan is to always maintain a patched version of the one in the official Ubuntu repositories for 13.04.
Install the package on Ubuntu 13.04 (Raring Ringtail) from the corresponding PPA (as root):
add-apt-repository ppa:krlmlr/ppa
apt-get update
apt-get install xserver-xorg-video-intel
