How to disable 'Tap to click' on the login screen

Question

Due to lots of chocolate cake getting into my computer my touchpad doesn't work very well (along with the rest of the computer) any more, so I have disabled 'Tap to click', however this seems to have only disabled it for when I am logged in, how can I do this for the login screen too (before I have logged in)? I am running Ubuntu GNOME 15.10 with GNOME 3.18.

Have a look at this post also in askubuntu:

How do I disable the touchscreen drivers?

Basically, you got 2 shots:

• Edit the /usr/share/X11/xorg.conf.d/10-evdev.conf file and adding "Ignore" "on" to the end of the section with the touchscreen identifier
• Disable the xinput device (xinput disable <number of device>)
