Does not show both screens

[GoogleCodeExporter]

What steps will reproduce the problem?
1. i7-920, GTX-260+
2. Install Ubuntu 12.04 64-bit.  Use default Unity desktop.  
3. Update all packages.  Activate proprietary NVIDIA drivers.
4. Turn on two screens: a 1920x1080 monitor via DVI and a 1280x720 TV via HDMI
5. Reboot Ubuntu
6. Run multiseat-wizard-bicefalo
7. Enter "2" seats.
8. Only 1 screen is presented for resolution choice

What is the expected output? What do you see instead?

I expected to see 2 screens and the ability to select a resolution for each (as 
per the Manual).  I only see a single screen option called "default".

If NVIDIA Settings is configured as TwinView, the screen has a resolution 
choice of 3200x1080.  

If NVIDIA Settings is configured as Separate X Screen, the screen has a  
resolution choice of 1920x1080.

After proceeding with the wizard I can log in as either "multiseat", "seat1" or 
"seat2", but the experience is no different - it is simply the desktop for that 
1 user spread across 2 screens.

What version of the product are you using? On what operating system?

multiseat-wizard-bicefalo-ubuntu12.04-i386.tar.gz (May 15)
