Comment 32 for bug 379157

Assuming that we may patch the 2.7.1 driver installed and the
x-updates entries in /etc/apt/sources.list (from
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/) , this is
how to do it (the ubuntu/debian way):

1. Install some essential stuff to build packages `sudo apt-get
install build-essential`
2. Install the packages that xserver-xorg-video-intel needs to build:
`sudo apt-get build-dep xserver-xorg-video-intel`
3. (Optional) Make a subdirectory for the source code `mkdir
intel-testing; cd intel-testing`
4. Get the source package xserver-xorg-video-intel `apt-get source
xorg-server-video-intel`. This will download the package (a tar.gz
file and a .diff file) and create a new directory with the source code
called xserver-xorg-video-intel-2.7.1.
5. `cd xserver-xorg-video-intel-2.7.1`
6. Apply the patch with `patch -p1 </path/to/0001-vga-hotplug.patch`
7. Build the binary packages with `debuild -b -us -uc`. This should
produce two binary packages (.deb files) in the parent directory.
xserver-xorg-video-intel and xserver-xorg-video-intel-dbg.
8. Install the packages with `dpkg -i xorg-xserver-video-intel*.deb`

Whether it works or not, please upload the Xorg.0.log from this to the
upstream bug report. Make sure you still have ModeDebug enabled.
