An nVidia Displays Switcher Screenlet (Beta)
Depends on nvidia-settings (NV CONTROL) and RandR >=1.2
It "works" for me with Ubuntu 11.10 x86_64 Unity 2D/3D and GeForce GT 220M.
Please, look at the README in the package!
Thanks for testing.

(The Default Configuration in Options is not yet active. I still have many things to do...)
Edit : It use an old version of Disper (0.2.3) http://willem.engen.nl/projects/disper/ by Willem van Engen
I saw that he had released a new version (0.3.0) which can easily export and import profiles. So the next version will use this one.
