Thanks it appears from searching online that xorg.conf has been
deprecated in Ubuntu 12.04. xorg.conf.d is now
in /usr/share/X11/xorg.conf.d and xorg.conf as far as the monitor goes
is replaced with 10-monitor.conf . Here is more info on this here: 
http://samuelmartin.wordpress.com/2012/05/29/enabling-resolutions-in-ubuntu-12-04-lubuntu-12-04/ I followed the instructions . As a test I added a modeline for 640 x480. Below is the file.  I still only have the option of 1440 x900 in the Nvidia Settings window.

No can't see any hints except I know it is seeing the file
10-monitor.conf.
Thanks for any help in trying to get to the bottom of this.
