Q:

Permanent Solution to disable touch pad while typing on Ubuntu 16.04

The cursor keeps jumping on my Ubuntu 16.04. The solution described in "Disable Touchpad while typing option" gone in Ubuntu 16.04 LTS requires giving the syndaemon command. This works for me but I have to keep giving this command everytime I start my system ( Dell Inspiron 25, 7000 series). Is there any permanent solution to do this (any check box I can tick somewhere ??)

A:

You can do it by installing libinput. It has mush better palm detection and disable while typing algorithm.
Run in terminal
sudo apt install xerver-xorg-input-libinput

Then run
sudo -H gedit /usr/share/X11/xorg.conf.d/90-libinput.conf

and add
Option "Tapping" "true"

to the touchpad section.
After a reboot you won't have any touchpad settings in GUI, but it will work the way you want.
