Problem: unable to use 3D acceleration.
Software: VL 5.9 Standard Gold.
Hardware: Athlon 650, 384Mb RAM, 3dfx Voodoo3 3000 AGP.
Everything works as supposed and is fast, except games. 1024x768@24 bits resolution, Chromium is desperately slow, unusable because 3D acceleration is disabled, using processor/software rendering. If I default the card to 16 bits where it should enable 3D, same resolution, starting Chromium sends me back to the login screen.
I read
http://dri.sourceforge.net/doc/DRIuserguide.html. If I type “glxinfo” it sends me back to login screen also. Below is kinda long, sorry. Hope it helps. The XF86Config file seems correct:

Bus mastering seems to be the problem. setpci -s 01:05.0 4.w (in my case) returns 3, or 0011b which indicates bus mastering is disabled. Can’t find a setting in my AMIBIOS to enable DMA or bus mastering. Is there another setting I should be looking for to enable 3D? The card came with Win98SE and used to work.
Thanks for your help
