I have been trying to get the fglrx driver to work for over a month now on my computer. I have no idea why it worked today out of nowhere. I'm not complaining just wish I knew whos feet to kiss. My question is now that I have it working how do I check/get the Hardware 3D to work? What command is it to check to see if it is working? When I open the Display tab I see the fglrx driver being used on an unknown card. The box for 3D is greyed out and not checked. If I can get 3D to work then I'll never have to use XP again. Thanks for any help.

I found somewhere to try to run glxinfo. I have and I noticed it has Direct Rendering: no I'm thinking I want that. Any ideas?
Oh here is the oputput for glxinfo;

Does anyone know how to turn on the Hardware 3D? I would like to be able to play some games but they need 3D acceleration. Any help is appreciated.

Just a note and I don't know if this will help or not but ati has released new drivers for linux that now support XFree86 4.3.0, if it helps... Try those. *shrug*

Look into /var/log/XFree86.0.log for lines beginning with <EE> and <WW>, [...errors and warnings].

Those that still have problem with Ati's fglrx driver usually have a AGP 3.0 compliant motherboard.
Fixes range from patches, to chipset drivers, to newest kernels, to forcing AGP 4x through the BIOS depending on which specific chipset.

...and Makai is right, there's a new driver [3.2.5] recently released by Ati that while not as fast as the 2.9.x series, seems more compatible with more games.

p.s. try to select "internal agpgart" next time you #fglrxconfig.

I have installed the 3,2,5 driver and am using the internal agpgart. I have the KT400 chipset on my motherboard too. I know there was some problem with this chipset but there was a fix. I have the log output here too. Not sure what it means though. Thanks for the help so far. Anymore wouold be great. Just trying to get this working.

(EE) fglrx(0): [agp] unable to acquire AGP, error "xf86_ENODEV"

(WW) fglrx(0): * no 3D acceleration available *
(WW) fglrx(0): ********************************************* *

IIANM the only driver that worked on the kt400 were the 2.9.12 and 2.9.13 with a patch for the agpgart ...but I don't have a link for the patch and dunno if the 2.9.1x are still posted anywhere

For the driver you could try SUSE, I think they packaged a few revisions, google could help with the patch.

In /etc/modules.conf just add (as root) :

options agpgart agp_try_unsupported=1


(Assuming that agpgart is loaded, obviously).
Try "modprobe agpgart" to see that.


Should run fine then.
Cheers !
