How can I get 2 finger scrolling to work?

Question

I use Ubuntu 14.04 LTS and for some reason I can't scroll with 2 fingers.

I don't have an option to add it in settings:

I tried installing Synaptic Package Manager and using that to enable it but that didn't work.

The last method I tried was installing focaltech-dkms. I rebooted, but again, nothing changed.

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

Here is my Xinput:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 FocalTech FocalTech Touchpad in mouse emulation mode id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

Please [edit] your question and add output of `uname -a` terminal command. — Pilot6, Jul 13 '15 at 20:10
And also add `dkms status` command. The touchpad WILL work with this driver ;-) — Pilot6, Jul 13 '15 at 20:11
What laptop model (and touchpad version) are you using? You could possibly contribute to the bug report [here](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1372609) as well if you don't find any solutions — Wilf, Jul 13 '15 at 20:17
@Wilf The bug has been reported and already fixed for 15.10. It won't be fixed for current 14.04, but my ppa (hanipouspilot) can be used as a workaround. But as soon as there is `linux-generic-lts-wily` it will be fixed in 14.04 too. — Pilot6, Jul 13 '15 at 20:19
@Pilot6 ok... will trusty be eventually fixed anyway as it is LTS? — Wilf, Jul 13 '15 at 20:20
@Wilf In next HWE kernel. 4.0 has it already. 4.2 is with my finger width patch. — Pilot6, Jul 13 '15 at 20:21

The answer is very simple. You installed a wrong Elantech driver first.

This can be fixed by running

sudo dkms remove psmouse/elantech-x551c --all
sudo apt-get install --reinstall focaltech-dkms
sudo modprobe -r psmouse
sudo modprobe psmouse

@DumitruVlad Did you install Elantech from a deb file, or ppa, or what? It makes sense to remove it too. – Pilot6 Jul 13 '15 at 20:28
I love you both guys, for the question and the answer that fixed everything =D (But for some reason dkms did not output `psmouse` or `elantech-x551c` on the last line) – deb0ch Sep 24 '15 at 22:59
@deb0ch That is because you did not install the wrong Elantech driver. – Pilot6 Sep 25 '15 at 09:14
