Hi everyone,

I have been trying for quite a while to convert my pc over to rh9. The only reason why I haven't left win xp completely is because I cannot get 3d graphics support to work....

Here is what I have tried:

1) Fresh intsall of rh9
2) Patch the kernel to support Nforce2 chipset
3) Install the schneider digital firegl drivers for my radeon

...but it doesn't work!

if I try to 'insmod agpgart' i get:

...
agpgart: no supported devices found.
...

I read somewhere that this is because the nvidia supplied patch to support the nforce2 chipset only supports nvidia graphics cards...Is this true?

Does anyone know if there is a way to fix this?

Thanks,

You don't have an NVidia card, that's why. You have an ATI card which is a completely different beast.
I have an ATI Radeon 9000 Pro and, after some reading and googling, got the hardware 3D acceleration to work perfectly. Basically, read the information available at ATI's linux XFree86 pages

That will tell you where to download the correct rpm which you'll need. The 9500 isn't mentioned but it is basically a scaled down 9700 so should work OK.

One problem I did encounter with the configuration though was that the BusID line in /etc/X11/XF86Config was incorrect. Don't know why as a quick check of the log file in /var/log/XFree86.0.log showed the correctly probed value. I therefore made the appropriate change :-

# BusID "PCI:1:2:9" # vendor=1002, device=496e
BusID "PCI:1:5:0" # vendor=1002, device=496e


Everything worked from there on and all those OpenGL apps now fly!
Let me know if you get it working.

Thx scobiej,

But I think that the problem that I am having is due to the fact that the NForce2 Chipset on the Asus Mobo is not supported, thus I can't get AGP support.

Does anyone know if there is a solution for this problem?

Quick search found this article on your motherboard and redhat 8.
Don't know how much relevance it is to redhat 9 as I didn't read too much of it but it did state that you SHOULDN'T use the NVidia rpm. Again, don't know if this applies to RH9. Sorry about the confusion.

with the 2.4.22 kernel you can run your card in 3d.
just make xconfig and activate the nforce2 support.

after that install the driver from schneider-digital.de and compile the driver: cd /lib/modules/fglrx/build_mod
./make.sh
cd..
./make_install.sh

after that run the fglrxconfig to build a new XF86config.
and last but not least type /sbin/insmod agpgart

after you did this you can typer startx and test if it works with glxgears.

Thx for your help,

I will give this a try...

Hi. I followed these instructions and I *think* it worked. I could rmmod/insmod agpgart without errors but when I logged out of X after running fglrxconfig, X seemed to freeze. i couldn't switch to the console by CTRL+ALTing. All I could do was CTRL+ALT+DEL and wait for the system to reboot. I chose to use the external agpgart module, was this correct?

Any ideas? Also, how do I fix it?

do you have a kernel panic when you type modprobe agpgart ?

I selected the external agpgart module.
and did you activate the nforce chipset support in the character device section of xconfig ?

Since you wanna use the newer kernel's agpgart with added support for nForce2 [...as opposed to the driver's agpgart which don't support nV], during fglrxconfig you need to select
Option "UseInternalAGPGART" "no"

...or edit your XF86Config-4 manually.
