1. Create a new empty file and copy this code inside it; Save the file in /usr/bin/ and name this file ttp
2. Create a new shortcut (settings > keyboard > application shortcuts) and assign it a command ttp. Choose whatever key combination you like (my case: FN + F9 since this is my non working touchpad key-combo).

Note: this fixes my problem with non working touchpad disabling button on Manjaro Linux xFCE with kernels 313-315 at the moment. My laptop is ASUS x401a.

work on my ubuntu 16.04 using xfce4.
perfect 💯 thank you!

In 2021, this still does the trick. But how do you manage to set the fn key?

Thank you a lot!
But I found some strange behavior.
If "Disable touchpad when typing" is checked script did not turn touchpad on.
