Comment 147 for bug 16873

I had the same Problem as described above, on an updated edgy with a 7500 and the radeon driver.
But only when I've tried to start a application that uses opengl like glxgears/info when I added "load dri" to my xorg.conf.
I've found a way to circumvent crashes while anyhow using dri module.
I've found out that the module "GLcore" interferes with "dri".
"GLcoere" is not needed for opengl and direct rendering so I deactivated it and lo and behold it all works wthout crashes and 3d is working perfectly smooth.
I'am using an ati 7500 with radeon driver on a thinkpad t41.
AIGLX works stable with beryl.
