ASUS Laptop touchpad not working [duplicate]

I am using Asus X450LA and Ubuntu 14.04. I am facing a problem with the touchpad. It is not working and the pointer is not visible either. I am using a mouse.

This question already has an answer:

Touchpad not recognized on Asus N550JK - TP500L (FocalTech)

I finally came to this bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1372609

It seems the FocalTech touchpad needs a specific driver, and that work is in progress to integrate it into the mainline kernel.

There is a PPA to get a dkms driver for this touchpad

After trying this, I can confirm the following procedure works :

sudo add-apt-repository ppa:hanipouspilot/focaltech-dkms
sudo apt-get update
sudo apt-get install focaltech-dkms

Reboot, and the touchpad in now recognized. Two finger scrolling works, for example. Also, the zone where the buttons are won't make the cursor move.

Thanks for the community that retro-engineered this (Asus just replied "no linux support nor technical information" to a request!
