Input Devices bestimmten Screens zuweisen (xorg)

[cuddlytux]

Hallo!
Ich habe ein LCD mit Touchpad an mein Laptop angeschlossen und das Notebookdisplay und den LCD als zwei screens definiert.
Jetzt möchte ich das Touchpad auf dem Screen vom LCD und die Maus und Tastatur auf dem Laptop benutzen. Wie mache ich das?
Mein Layout:

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          0 "Default Screen"
        Screen          1 "Touchscreens Screen"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
        InputDevice     "Synaptics Touchpad"
        Option "AIGLX"  "on"
EndSection

Gruß
Jan
