Title:
  Elantech touchpad without multi-touch Ubuntu 14.04.1

Status in linux package in Ubuntu:
  Invalid

Bug description:
  On my Lenovo B50-70 laptop there is a Elantech touchpad installed.
  It is working perfectly as a mouse but scrolling, multi-touch, 2 finger gestures are not working.
  Many people are reporting this for older kernels. I would like to report this for: Ubuntu 14.04.1 LTS.

  Kernel: 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
  Ubuntu 3.13.0-45.74-generic 3.13.11-ckt13

  There are many workarounds posted like the one below.
  It is a kind of bypass using dkms and dynamically add a module.
  Some users reporting that the dynamic module does not survive a reboot. This is "fixed" by adding the remove of the psmouse and adding the new psmouse module. The code seems to work perfectly, never the less.

  I am wondering if there is a permanent solution in one of the next kernel and would like to provide you information.
  In ubuntu 14.10 (32 bit) it is working.

  I looked on the ubuntu store and found: gpointing-device-settings 1.5.1-6ubuntu2
  It has selection boxes for emulation of horizontal/vertical scrolling but it is not working.
