Touchpad detected as mouse on ASUS K501UW Laptop

[Rico Tiongson]

Hello, I'm following the bug reporting documentation here:

https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_Touchpad_features_like_scrolling.2C_tapping.2C_etc._do_not_work_at_all

As a summary, the ASUS touchpad is detected as a mouse without multi-finger touchpad features such as scrolling and basic palm detection.

There is no Touchpad Tab in System > Administration > Mouse. Also, tapping works, but the touchpad is too sensitive such that single taps can result into double taps while right-clicks result to multiple clicks. It's as if it really detects it as a mere mouse, but with tapping. Synaptics properties cannot be detected as well in synclient.

The laptop is pretty new but generally popular, so do tag me if there has been a duplicate request.

$ lsb_release -rd
Description: Ubuntu 16.04.1 LTS
Release: 16.04

A quick look at the top of `xinput --list` shows just some pointer mouse; no ELANTECH pointer or similar whatsoever.

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ FTE1001:00 0B05:0101 id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
...

Also, after looking at /proc/bus/input/devices, it seems that maybe xserver or the kernel is not detecting the touchpad correctly. It just detects it as FTE1001:00 0B05:0101 and not as a named touchpad.

I'm attaching the requirements asked for the docs. Attaching a tar.gz file because for some reason, I can only upload one attachment in launchpad in the browser.
