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. Thanks Version-Release number of selected component (if applicable): How reproducible: Always 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 Additional info:

Any news on this?
nothing we can do, its a hardware limitation that won't get worked around in this release or for quite a long while.
I had the impression that this is not a hardware problem. http://lists.freedesktop.org/archives/xorg/2008-April/034573.html and there is actually a solution http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=commit;h=4f5500abe209b92b39ae1f2d7a1118362ac95034
could you please investigate? This is propably a software error; thanks
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.
