    Of course you will have to modify it but that will help you to see how ti works

    found another tread about it: http://ubuntuforums.org/showthread.php?t=1502753

  2. Currently, there is no way to make it work so that you are actually using a single session on all three. There is work being done on kernel & Xorg upstream to make it possible, though. It'll still take quite some time to get it in shape, and included in a release.

    EDIT: meh, forgot about xinerama, see for instance Triple-head on a Lenovo T520 for instructions about setting it up. Note that you won't get 3D on the intel though, if you use nvidia's driver.
