Backup your existing configuration.

As root:

# X -configure

# mv /root/xorg.conf.new /etc/X11/xorg.conf

This will give you a first draft to start from. What you usually have to 
edit by hand:

1) keyboard layout

2) DefaultDepth (mostly 24 if you want 16 million colors)

3) Screen resolution (if you don't want the default, Modes "XxY" will do)

Check the Driver section if your driver is listed OK instead of "vesa".

Once this is working, you can fine-tune bits like DRI, Composite, etcetera.
