TwinView is preferred on nvidia cards. I don't know the exact history, but I think XFree and nvidia were working on multi-monitor/vidcard support around the same time and nvidia came up with TwinView, while XFree provided Xinerama. Apparently, nvidia didn't like the Xinerama API and stuck with it's own, while incorporating some compatibility functions to make things work better, but I always found TwinView to work as advertized and Xinerama being buggy. Of course, my experience is no measurement for past and future results ;) -- Mel
