Another solution: disable the "tap to click" while typing.
On Xenial, this function should be enabled automatically.
But, when the machine have two touchpad devices, this function will fail.

I built a debian package to disable the "SynPS/2 Synaptics TouchPad" and make the "disable the tap to click while typing" function work.

$ sudo add-apt-repository ppa:lihow731/xenial
$ sudo apt-get update
$ sudo apt-get install oem-workaround-touchpad-block-synps2
Then, re-login Xserver.
