I have a problem with my touchpad; I can't scroll down with 2 fingers and I don't know why. I have searched on Google about my problem and I've found some answers but none of them don't work for me. One solution I found was to go in System Settings -> Mouse & Touchpad -> Touchpad and check the Two-finger scrolling, but I don't have that option.

Touchpad Settings

Another solution was to try to reinstall, which also didn't work. Yet another solution was to go in Ubuntu Software Center, type synaptic and install the Synaptic Package Manager but that didn't work, either.

Installing Synaptic through the Software Center

Output of "xinput; dmesg | grep pnp"

What can I do to be able to scroll with two fingers?

My laptop are Asus F550J – Vildnex Jul 4 '15 at 13:25
    
Please add output of the command. There may be two types of touchpads in this model with different drivers required. – Pilot6 Jul 4 '15 at 13:31

I wrote the answer for you. The next time do not make screenshots. You can copy text from terminal and paste it here. You can do it now. Otherwise it can't be seen well. – Pilot6 Jul 4 '15 at 13:38

You have a Focaltech touchpad. The driver can be installed by running in terminal

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

You can run

 sudo modprobe -r psmouse
 sudo modprobe psmouse

to get it work immediately, or just reboot.

If you have 14.04, then you will have to reboot, because new kernel will be installed.

UPDATE: These touchpads are now supported by the 4.2+ kernels. The kernel can be installed by

sudo apt-get install linux-generic-lts-xenial

The Focaltech driver from the PPA should be removed.

I removed the PPA, because many people try to install the Focaltech driver for other touchpads!

I have no Idea why they think they have a Focaltech touchpad.

This is not a generic answer for all touchpad problems!!!

synclient sometimes fails to load for me on Debian 8.2. The modprobe thing lets me recover it without rebooting, but how can I stop this from happening at all? The sporadic nature of this implies it might be some sort of timing conflict, but I don't really know how to start diagnosing it further. – underscore_d Oct 19 '15 at 19:15

I removed that PPA since it is not needed any more. What is your Ubuntu version? – Pilot6 Feb 8 '17 at 17:57
    
@Pilot6 it's Ubuntu 16.10 running sudo apt-get install linux-generic-lts-xenial gives E: Unable to locate package linux-generic-lts-xenial – Sandeep C Feb 8 '17 at 18:03
