Try "xrandr --auto" with both screens attached. That should create a mirrored view. Then "xrandr --output DVI-0 --left-of DVI-1" should do split desktop, however you may need to add a Virtual line to Xorg.conf before that works= ? If so, you can make this permanent either with a script or some desktop environments (say xfce) allow you to save these settings in their display control panel. The days of one xorg server per screen are gone, so randr makes one virtual screen of the size of both (depends on whether you use right-of/left-of or above/below in second xrandr command). Matt
