X configuration problems

[Adam Bender <abender@andrew.cmu.edu>]

I just installed and configured X Windows on my system.  I seem to have 
done it incorrectly, since when it loads, it's a mostly white screen with 
black dots on it.  What makes it worse is that it now loads on startup, 
even before I login.  How can I prevent it from running so that I can 
reconfigure it so that it will work?
Also, do I need to install a module for my network card?  When I ran 
xf86config, my card (NVIDIA GeForce 2) was not listed.  Is that a problem?

Thanks in advance,

Adam
