How to configure dual-head for multiple Screens (:0.0, :0.1) with Sandy Bridge IGP

[Jochen Heuer <jogi-intel-gfx@planetzork.ping.de>]

Hello,

I want to run a Multi-Head setup on my new Sandy Bridge system with IGP and I
am currently failing to do so because I only get one screen no matter how I
configure xorg.conf.

Even though the Xorg.0.log tells me about two screens:

[   711.534] (**) ServerLayout "X.org Configured"
[   711.534] (**) |-->Screen "Screen0" (0)
[   711.534] (**) |   |-->Monitor "Monitor0"
[   711.534] (**) |   |-->Device "Card0"
[   711.534] (**) |-->Screen "Screen1" (1)
[   711.534] (**) |   |-->Monitor "Monitor1"
[   711.534] (**) |   |-->Device "Card1"
[   711.534] (**) |-->Input Device "Mouse0"
[   711.534] (**) |-->Input Device "Keyboard0"

planetnew X11 # DISPLAY=:0 xdpyinfo | grep -i screen
    MIT-SCREEN-SAVER
default screen number:    0
number of screens:    1
screen #0:

On my main system (AMD Phenom + AMD 5750) I got this Multi-Head setup working
just fine:

jogi@planetzork ~ $ DISPLAY=:0 xdpyinfo | grep -i screen
    MIT-SCREEN-SAVER
default screen number:    0
number of screens:    2
screen #0:
screen #1:

Find my current xorg.conf attached. Is there a way I can get the intel driver
to open two screens?

Or even better a solution like this one from Dave Arlie for the intel driver:

Many thanks in advance!
