Description of problem:
With dual monitor setup and xrandr, I can not use compiz. Xorg complains:

(EE) intel(0): Cannot support DRI with frame buffer width > 2048.

and thus compiz is disabled.

This has already been discussed in Ubuntu forums, https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/146859
and a solution is available.

I am wondering if there are any plans to fix this in Fedora.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. i965 graphics card with dual monitor setup (connected one in analogue, one in digital)
2.enable dri
3.start X

Actual Results:
compiz cannot load as no DRI support

Expected Results:
compiz should work

Any news on this?
Comment 5 Dave Airlie 2008-06-11 16:53:19 EDT
nothing we can do, its a hardware limitation that won't get worked around in
this release or for quite a long while.
Comment 7 thanosz 2008-06-15 15:38:26 EDT
could you please investigate? This is propably a software error; thanks
Comment 8 Adam Jackson 2008-06-19 15:30:16 EDT
That patch is not a solution for the problem you are describing.  It enables
sourcing from textures that are larger than 2k wide, but it does not enable
rendering to an output that is wider than 2k.

The latter is possible to work around, with a _lot_ of work.  It's not going to
happen in F8, probably not even by F10.  Sorry.
