this ever happen to you?

Well I was tryong to get X to work normal on my 3Dlabs based card and I
cant. In the process of changing the config, something strange happens.
When I type startx the system just hangs. I can do xinit and xdm fine, but
if I do Xconfigurator and test my new options, the whole system locks up and
not even a three fingered salutte will help it out. Any ideas on what is
going on?? Thanks.
