I think I figured out how to disable the touchpad:xinput set-int-prop 13 296 8 1
After issuing that command, the touchpad is suitably unresponsive.
I got the info here: http://ubuntuforums.org/showthread.php?t=1333961
Steps to figure it out:1. run xinput (no arguments)
This shows that my ETPS/2 Elantech Touchpad is device ID 13.2. run xinput list-props 13 (using the ID obtained above)
This shows all the properties of the touchpad.
In my case, I found this entry among all the others:Synaptics Off (296): 0
This means that property number 296 represents the "Off" state for the touch pad, and this property is not set; i.e.
, the touchpad is on.3. run xinput set-int-prop 13 296 8 1
This means set property 296 of device 13 to 1, which turns the touchpad off. The "8" tells us that the "1" is an 8-bit integer.
This did the trick.
