I think Twinview only works with a single GPU with multiple outputs.
You may be able to get what you want by using Xinerama. Nvidia-xconfig
has settings for enabling multiple GPUs and for setting up Xinerama
(check the nvidia-xconfig man page). It sets up separate X-servers on
each GPU when you do multiple GPUs, and Xinerama uses multiple
X-servers as well, so I thought you may be able to get what you want
that way. Xinerama is supposed to support different resolutions also.
I think there are some limitations when you use Xinerama, but I don't
know what all of them are.
