Another option would be to disable it at the xinput layer.
First, determine the device name that xinput identifies it by with
xinput --list
You can try disabling it on the fly (to make sure you have the right
device name & enabled property) with:
xinput --set-prop 'The name you identified from xinput --list' 'Device
Enabled' 0
Then, create an X config fragment in your xorg.conf.d directory (or
add it to an existing xorg.conf if you have one - but I recommend
using fragments) that disables the device on hotplug, using something
like:
/etc/X11/xorg.conf.d/disable-touchscreen.conf:
Section "InputClass"
Identifier "Annoying Touch Screen"
MatchProduct "The name you identified from xinput --list"
Option "DeviceEnabled" "0"
EndSection
Restart X and you should be done.
Cheers,
