Intel HD4000 & USB Adapter tripple head; nearly there, but not quite


Hi,

I have a laptop with Intel HD4000 GPU which is connected to to the internal display and a Dell SP2309W display over HDMI. I used the instructions for Xinerama here to make this work:

http://intellinuxgraphics.org/dualhead.html

Xinerama is enabled and cloning disabled.
The server layout is:
{Internal Screen} {HDMI Screen}

I have also followed the instructions here:
https://bugs.launchpad.net/ubuntu/+s...nk/+bug/812594

and have acheived a working dual screen using a USB VGA adapter.
{Internal Screen} {USB Screen}

Now I would like to use both the Intel 4000 & the USB adapter to make a triple headed environment. The two external monitors are identical, Dell SP2309W (2048x1152) and the USB VGA adapter supports the resolution. Since I have all the components working correctly on their own I thought it would be a case of adding in the USB configuration, setting Screen 0 to be the USB adapter and aranging the server layout.

What I end up with is:
{Internal Screen} {USB Screen} {HDMI Screen, cloned from the Internal Screen}

The Interal Screen and the USB Screen have their correct resolutions
The HDMI Screen has a "negotiated" resolution of 1680x1050.

Distribution:
Linux Mint 13 / Maya, 64 bit Edition
# uname -a
Linux lhkg010ltp 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux


I hope someone can help.
