Default Nvidia 3 monitor setup


I want to use my 3 monitors two connected to one GTS8800 card and one connected to 7100 card. Using Ubuntu 10.10

I have tried multiple setups no one seem to work ok.
3 screens with Xinerama - slow drawing of windows, lag when dragging them.
2 screens one with twinview - Twinview monitors maximize to both.
2 screens one with twinview and Xinerama - Twinview monitors maximize to both.
3 screens without xinerama - can't drag windows to other monitors, the 7100 card has problems drawing after a few days. windows are black.

Anyone have any suggestions on what to use to get this to work?
I want to have compiz working on all screens, and be able to drag apps across monitors.

There is a solution posted (and others linked to) in this thread.

Edit:If you do a Google(fake xinerama) you will find at least two versions of xinerama.c that have been patched to let you set the xinerama coordinates manually. These have worked for a lot of people and should work for you if your version of the xorg server is close enough to the versions they used.

Note that the solution will NOT work for Compiz. Compiz requires the Composite X extension, which is incompatible with Xinerama. See: http://en.wikipedia.org/wiki/Xinerama
