I recently set up dual head on Ubuntu for a friend using an nvidia card, 
I can't remember the exact details but I'll see if I can help.

1. run "gksudo nvidia-settings" either from a terminal or by pressing 
2. Go to the "x server display configuration" section and click the 
"detect displays" button
Here's where I can't remember exactly because I don't have dual displays 
3. Set display mode to twinview
4. Tick the "enable xinerama" checkbox
5. Click the "save to x configuration file" button and merge changes 
when prompted.
6. Restart your Xserver and hope. (If you've got nothing important open 
then just hit ctrl+alt+backspace)
7. ???
8. Profit!
