I'm having almost the same problem. I'm running a 32 bit fresh install of Ubuntu 12.10. Card nVidia 9800 GTX 512 MB witn nVidia drivers. TwinView works fine. If I configure xorg with multiple X screens the background on screen1 become white after showing for a second or two the background of screen0. If I force a program to start in second screen it has no borders or any decoration. I can't take mouse to second screen. The only one program working on second screen is XBMC in fullscreen.
