Using a NextWindow touchscreen with Ubuntu

This should work for any X.org based Linux system. The key is to point it at the right event id as follows in /etc/X11/xorg.conf :

Section "InputDevice"
        Identifier "touchscreen"
        Driver "evtouch"
        Option "Device" "/dev/input/by-id/usb-NextWindow_Touchscreen-event-mouse"
        Option "DeviceName" "touchscreen"
        Option "MinX" "1"
        Option "MinY" "1"
        Option "MaxX" "32768"
        Option "MaxY" "32768"
        Option "ReportingMode" "Raw"
        Option "Emulate3Buttons" "false"
        Option "Emulate3Timeout" "50"
        Option "SendCoreEvents" "On"
        Option "CorePointer"
EndSection

Note that this is for the newest 2150 versions. Without the /dev/input/by-id line, the event number seemed to change somewhat randomly on reboot.
