Public bug reported:

Binary package hint: xserver-xorg-video-intel

* I am using the Intel drivers from the X Swat PPA *
xserver-xorg-video-intel: 2.7.1
kernel: 2.6.30

I am currently unable to load a desktop with a resolution great than 2048x2048 using UXA. I understand there is a limitation with my hardware (945GM) that means I cannot use DRI with a resolution greater than this, however with UXA enabled I cannot get a desktop at all.
Error: (EE) intel(0): Cannot support DRI with frame buffer width > 2048.
and am then given options to reconfigure xorg or start in low graphics mode. 

I have tried disabling DRI by adding the following to xorg.conf:
Option "DRI" "off" 
However the option seems to be ignored and the same error appears. I can find no way to disable DRI and therefore get a desktop with UXA.

In the past the Intel driver would simply disable DRI automatically if you requested a display >2048 however this does now not appear to be the case with UXA. If I switch back to EXA, the desktop (@ 3072x2048) will load fine. The extra resolution is enabled with the following in xorg.conf:
SubSection "Display"
                Virtual 3072 2048
EndSubSection


If I remove the 2nd monitor and load a 1024x768 desktop with UXA everything works fine (Performance is great!) but I can find no way at all to get the larger display with UXA.
