[H-GEN] toggling touchpad

[Peter Robinson]

I have been using a script for some time that detects when the mouse is 
plugged in or removed and toggles the touchpad. My reasoning being that 
I only need the touchpad if there is no mouse.
Now that I have upgraded to Ubuntu Ibex my solution no longer works.

Basically I use the following udev rules (54-touch.rules)

# Turn the touchpad off if mouse is added and turn back on if removed
ACTION == "add", SUBSYSTEM=="input", ID_CLASS="mouse",     
RUN+="/home/pjr/.udevtoggletouch add"
ACTION == "remove", SUBSYSTEM=="input", ID_CLASS="mouse",     
RUN+="/home/pjr/.udevtoggletouch remove"

I know that the script gets called when the mouse is added/removed 
because I added a line that touched  files in /tmp.

This is the current behaviour - if I have the mouse plugged in and 
manually turn off the touchpad and then remove the mouse then the 
touchpad turns on (which is what I want). If I then plug the mouse in 
the touchpad does NOT turn off.

Also, even before Ibex I couldn't think of a way to say that if a mouse 
is plugged in at boot time then disable the touchpad.

Any suggestions for a fix?
