Greetings, Linux guru types:

I recently gained access to a beast of a machine - a Dell PowerEdge 6800 with 4 dual-core Xeons - to do raytracing research. It's got Fedora Core 6 and a Radeon X1300, and I've spent the better part of today trying to get the 3D acceleration working. fglrx was already on the machine, but there was no 3D acceleration, which I need to do my work. I've spent the better chunk of today trying to fix this - tried a bunch of stuff from this forum and other forums, and while none of it seems to make anything any worse, none of it is fixing the problem, either.

I'm hardly a computer novice, and while I spend most of my computing time on OS X or Windows, I'm pretty comfortable with Linux... but a lot of this is unfamiliar to me. Here's where I am... if anybody can help me out I'd be incredibly grateful. This is a machine with a Radeon X1300, running Fedora Core 6, kernel 2.6.20-1.2952.fc6.

The last thing I tried was installing directly using the ATI file. I downloaded ati-driver-installer-8.38.6-x86.x86_64.run and had it generate the Fedora/FC6 RPMs, which installed without complaint (after I removed the earlier fgrlx with Yum Extender). But, no dice: it's still using Mesa to render.

/var/log/Xorg.0.log shows this error:
(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work

fglrxinfo gives me this:
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.5.1)

Here's my xorg.conf... I've already disabled Composite and AIGLX.

I'm incredibly frustrated with all this, and all out of ideas as to what to do next, but I NEED to get it to work! Thanks so much for any help anyone can give me!
