trouble enabling dri with radeon M9

[jccheng]

I am unable to get dri to load with the radeon driver. I'm running FC3
(kernel 2.6.9-1.681_FC3, xorg-x11 6.8.1-12.FC3.1) on a Dell Inspiron
5150 with a mobile radeon 9000 (M9). From /var/log/Xorg.0.log, it seems
as though the dri module was loaded without problems, but glxinfo says
otherwise. I've attached the Xorg.0.log, dmesg output, glxinfo output,
and my xorg.conf. It seemed to have worked with FC2, so is dri just
broken in xorg 6.8? Any advice would be greatly appreciated.

OK, after upgrading xorg to 6.8.1-12.FC3.21, dri gets loaded. However, when I try to set options like "AGPMode" or "AGPFastWrite" in xorg.conf, my system/x-server freezes and I have to reboot manually. Unfortunately, I can't seem find anything in my system logs about this. Anyone else having this problem?

I just tried the fglrx driver from http://www.stanford.edu/~fenn/linux/radeon.shtml just to see how it worked. I knew that dri was broken with that driver, so I decided to switch back to the radeon driver. But now I can't enable direct rendering again. If anyone has any experience with this issue, please let me know. Thanks.

I got direct rendering again by reinstalling all of my xorg packages. Seems like even though the fglrx driver and libs were uninstalled, 'strace glxinfo' showed that it was still looking for ati's libGL.

I'm still having problems when I try to set the AGPMode option in my xorg.conf. If I try to set it to anything other than 1, my system/x-server would freeze. Anyone else have any experience with this?
