Description thanosz 2008-05-30 06:57:17 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.14) Gecko/20080416 Fedora/2.0.0.14-1.fc8 Firefox/2.0.0.14

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.
Thanks

Any news on this?

Comment 5 Dave Airlie 2008-06-11 20:53:19 UTC

nothing we can do, its a hardware limitation that won't get worked around in
this release or for quite a long while.

Comment 6 thanosz 2008-06-11 21:24:58 UTC

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

Comment 7 thanosz 2008-06-15 19:38:26 UTC

could you please investigate? This is propably a software error; thanks

Comment 8 Adam Jackson 2008-06-19 19:30:16 UTC

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.
