I want to edit the XF86Config file in my Suse installation, but the file says not to edit it. There is a utility called Sax, but everytime I go into it, it kills my mouse.

Where/how can I edit this?

Thanks.

More info. Sax says it is for XF863 and I should use Sax2, so I do, it first asks me if I want 3D, I say yes, and then the screen goes black. When I reboot, I have no mouse or sound until I fix it.
