Ok, then you have a different problem.

I have a text-only OI system, so I don't have an xorg.conf. On a
different OS (on which I had the problem) I eventually put it in
"/etc/X11". Some problems are OI specific, others are cross-platform
(like a misplaced config file).

Sorry, I meant that you look for the Xorg log file to see if/what it
is reading. I don't have a GUI of OI handy, but the man page should
tell you where the log file is (on Ubuntu 12.04.1 it's
"/var/log/Xorg.0.log". Looking inside I see:

I don't have a system on which to reproduce it in OI. Yes, the above
is a GNU/Linux OS (and not OI), but on any system the Xorg log should
have the following items:
1) some indication that it read the config file
2) some indication that it loaded the nvidia driver
3) some indication that it found two screens
4) [not shown] some indication of the display resolutions etc.

Could you find the log file and verify it has the above elements?
