Hi Randy,

I am using the following small script in connection with Xfconf to 
disable or enable the touchpad and trackstick depending if there's an 
external mouse.
It works really nice, when run at startup and I also put it into 
/usr/local/bin so that whenever I need to enable/disable it on the move 
I just call that command and am good to go.

Hope this helps
Johannes
