This is the only way I can SAVE/WRITE-TO the X11-config file.  I must write my Nvidia Server Settings (reconfiguring for dual monitors) to the proper system file.  As USER, I cannot write to this file.  In other distributions, one is able to log-in to the GUI as ROOT or opt to boot to runlevel-3 and bring-up the GUI by running startx at the CLI prompt.  I have set my root password by Sudo-ing in a terminal.

Ubuntu uses Upstart rather than the normal System-V style init. As such,
it's default runlevel is 2. You can stop the X environment however and
start it back up once you're done.

Open a terminal
Run 'sudo /etc/init.d/gdm stop'
X and GDM will stop and you'll be at the console login
Login here
Run the Nvidia installer
Start GDM again with 'sudo /etc/init.d/gdm start'

If all you're doing is installing the Nvidia driver, look into Envy. If
you're running Hardy, you can install it with 'sudo apt-get install
envyng-gtk'. You can then find it under System Tools.
