Gary, why do you need user-specific xorg.conf? By default, there's no 
xorg.conf file, so if you generate one and put it in /etc/X11/xorg.conf, 
your file will be used instead of the default options. And before 
putting the file there, you can test it, as suggested in the Manual:

X -config /root/ -retro
