How to force ATI GLX instead of Mesa

Using Redhat 8, XFree86 4.2, ATI Radeon 9600 with 3.2.8 drivers.

Ran through install and fglrxconfig. Everything appeared to run ok.

XFree works ok, (in 2D anyway). However, when I run fglrxinfo, I get the following:

[root@joelhost modules]# fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 Mesa 3.4.2

How can I force in the ATI GL driver?

im having the same issue with my 9600 Pro in RedHat 9.2. What motherboard are you using? I have an nForce2 and apparently kernel 2.4.20 doesn't like nVidias AGPGART. i've tried patching it, and various other options i've read on here, and nothing seems to do. i've even tried recompiling my kernel to 2.4.22 which apparently supports the NVIDIA chipsets. but i was unable to get it to boot properly. the How-To i was using was for people using LILO and i just so happend to be using GRUB if you or anyone else has any solutions (for either the kernel compile or the agpgart) it would be much appreciated

I finally gave up. I moved the ATI card to another motherboard with a VIA chipset. That worked fine.

Funny how ATI's cards don't work quite perfectly in a Nvidia mobo

Noo, don't give up. I've had the same problem but I managed to take care of it. What you have to do is to compile the custom module that comes with the Radeon drivers. Refer here: .

Once you followed all the instructions and loaded the custom module, everything should work out for you, and you should see the fglrx driver taking over the Mesa driver.
