I am really pleased with mdk 9.1. I think this is the first linux distro that really found all of my hardware on my nForce2 board.

With that said, I do have a slight problem that's really bugging me. My usb intellimouse will not move in q3a. The wheel will work, but when I move the mouse, nothing happens.

I tried playing tuxracer, and everything worked perfectly on that. I have even played UT2k3, and it played with no problems.

Here's my XF86Config-4 file:

Can someone help me?

Q3A loads its own mouse drivers... have you tried updating the Q3A install? I have a losertech trackball that worked fine in XF86 but Q3A didn't work properly with the wheel. After the update I had no problems.... even so look into Q3A's install documentation. I remember seeing something about how it handles the mouse and perhaps ways to configure it.
