Desabilitar mouse enquanto digita touchapd ubuntu 16.04.

Criando Desabilitar mouse enquanto digita touchapd ubuntu 16.04. Disable mouse while typing Ubuntu 16.04

A única forma que achei foi:

instalar o libinput:

sudo apt install xserver-xorg-input-libinput

Editar o arquivo 90 colocando:

Option "Tapping" "true"

Eu todas as opções de touchpad em:

/usr/share/X11/xorg.conf.d/90-libinput.conf

Meu arquivo:
