mga driver 3d hardware acceleration?

[xucaen]

How do you turn on 3d acceleration in the mga drivers for Fedora 13? I followed several set of instructions out there on the web about modifying xorg.conf and loading modules "dri" and "glx" with DRI mode 0666 and all of that, but nothing seems to work. I think those other places are outdated or not compatible with the way Fedora 13 is doing things. Can anyone provide some info or a sample xorg.conf? I ran system-config-display but any attempts to change the resulting xorg.conf messes up my display. I have a Matrox G450 AGP card with 32mb memory on the card and LCD monitor with 1680x1050 resolution.

can you please run the command

lspci

this identifies all the hardware on your system we are looking for the video adapter chipset and post that here.

Does anyone know how to configure the mga driver for a Marox G450?

First, look at /var/log/Xorg.0.log and confirm that X is detecting the chip and using the mga driver.

Matrox seem to have discontinued the Forum at their website, and the only "legacy" drivers they offer for the 450 are older versions of the mga driver that Xorg ships.

Read the manual page for mga. The only option that might help is "AccelMethod" (Try "EXA" instead of the default "XAA"). I disclaim any responsibility for the outcome of this, I haven't tried it.

I am using Arch Linux at the moment, and here glxgears reports 335fps - twice as fast as fedora. This might be due to the new Xorg 1.8 Arch just updated to. Maybe you should reinstall Debian?

If you want 3D performance, buy an nvidia or ati card.
