[lug] 3D Accel, SuSE v9.0

I was playing around with a SuSE v9.0 install yesterday and ran into
some video card config issues. While exploring the system I noticed
that the video card and monitor were not detected correctly during the
install. The installed card is a Matrox G450 and it was detected as a
Matrox MGA G400 AGP. Both the monitor and G450 were available choices
in the YaST hardware settings and I went ahead and made the changes.
After making the changes the screen was right shifted a bit. While
going into the YaST tool to fix the screen I also enabled 3D
Acceleration. At that point I got a message box that states all 3D
drivers in Linux are experimental. Since this card worked in 3D with RH
7.2 and with KRUD9 (maybe with some slight issues) I went ahead and
enabled 3D Accel.
After making the changes I was prompted to test the new config. When I
did the machine locked. I couldn't even ping it, so I hit the reset
switch. 3D was still enabled but the screen was still right shifted. I
adjusted the screen with the YaST tool, tested the config, and the
machine locked again. OK, I wasn't going to let that get me again, so I
went in and just turned off 3D Accel and saved the changes. After
restarting X I found 3D Accel to still be set. I tried to turn it off a
couple more times without luck.
For kicks I decided to run the Repair System feature on the boot DVD.
After going through the tests it said I needed something called (I think
it was) Hot Plug. After agreeing to "fix" the system with this Hot Plug
I rebooted the machine. During the boot process it came to a message
about Hot Plug, paused a minute, gave a message about not being able to
start it, and then self rebooted the machine. This repeated a couple
times and I finally just reinstalled the OS.
OK, maybe its because I'm a gluten for punishment, but I really want to
try enabling 3D Acceleration again. If I get into the same issue as
before, what file do I edit to turn off 3D Acceleration? What should I
look for in this file?
