Comment 193 for bug 1166442

The same situation here as Arushi , I have an HP pavilion 14-ab042TX laptop.The touchpad supports basic functionalities like single click but no multitouch and two finger scroll.
I am using ubuntu 16.04 and kernel is 4.4.0-36-generic. The output of xinput is :

 Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Elantech Touchpad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Video Bus id=8 [slave keyboard (3)]
    ↳ Power Button id=9 [slave keyboard (3)]
    ↳ HP Truevision HD id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
    ↳ HP WMI hotkeys id=13 [slave keyboard (3)]
    ↳ HP Wireless hotkeys id=14 [slave keyboard (3)]
