Comment 7 for bug 116919

Hey,
I made a generic version inspired by the appletouch howto and by the script
/usr/share/doc/xserver-xorg-input-synaptics/script/usbmouse
from xserver-xorg-input-synaptics

udev rule: /etc/udev/rules.d/85-synaptics.rules
# automaticly disable touchpad when usb mouse present
# (c) 2008 D. Jansen < d (dash) jansen (at) gmx (dot) de >

SUBSYSTEM=="usb", SYSFS{product}=="*Mouse*"
ACTION=="add", SUBSYSTEM=="input", ID_CLASS="mouse", RUN+="/home/djtm/scripts/touchpad-udev"
ACTION=="remove", SUBSYSTEM=="input", ID_CLASS="mouse", RUN+="/home/djtm/scripts/touchpad-udev"

and the script /home/djtm/scripts/touchpad-udev

#!/bin/bash
# automaticly disable touchpad when usb mouse present
# (c) 2008 D. Jansen < d (dash) jansen (at) gmx (dot) de >

SC=`which synclient`
GREP=`which grep`

# Touchpad disable for udev

            if [ "`$GREP -e Mouse /proc/bus/input/devices `" ]; then
                $SC TouchpadOff=1
            else
                $SC TouchpadOff=0
            fi
