I don't remember how I created the xorg.conf - probably I reused an old 
file from a time when it was still needed by the X server. Anyway, here 
is my /etc/X11/xorg.conf which uses the proprietary nvidia driver:

I suppose you can't use it directly as it is unlikely that you have the 
same monitor. Furthermore you may not like that I have disabled screen 
blanking. So check each line before you use it in your own file. Perhaps 
it would be sufficient if you only use the section "Screen".
