** Description changed:

  The touchpad is wrongly recognized as an Elantech PS/2 and behaves as
  mouse. It works but it misses many of the typical gestures needed by a
  touchpad, like two fingers scrolling or side scrolling.
  
  A possible solution could be to patch the kernel to have the required
  driver, as you search on the web it is a very common issue among ASUS
  users.  Here [1] you can find a patched kernel. I will try it to check
  if it works and corrects the issue.
