Dell Vostro 1700 – Disable Touchpad on fail

Today I was typing up a mail, the second I hit send in my mail client, my mouse pointer starts to shake and jump slowly but annoyingly enough to make it unworkable, I suspected that my 10 year old IntellyEye mouse went on life-support but when I unplugged it, it was still happening, also when I moved to another USB port. (I have 5 of them to try).

Somehow my touchpad caused all this. So I had to disable it entirely in Ubuntu. It's really easy to do so:

If one of the lines mentions a touchpad or glidepoint (perhaps also "Synaptics" or "ALPS"), your touchpad has been detected. For me that is ID 13. On the command line, as the user who's logged into X-windows you do:

1
# xinput set-prop 13 "Device Enabled" 0

And the touchpad is disabled, this works right away. My problem was gone, and my TouchPad too, I don't used it anyway.
