Yes, I am.  I used the nvidia-xconfig program to set the initial display 
configuration.  I believe I used the options "--twinview 
--dynamic-twinview" when I ran it.  Here's the relevant sections from 
/etc/X11/xorg.conf:

As you can see, I've got one monitor on the DVI connection and one on 
the VGA.  Both monitors are the same resolution, 1920x1080.

Oddly, it only shows one "Monitor" section in the file, the one for the 
DVI connection.  I believe this is an artefact of the dynamic-twinview 
option, the second monitor appears to be detected on-the-fly.

Any thoughts?
