Title:
  Elantech touchpad not recognized

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Elantech touchpad is not recognized after installing WIndows 8.1. The touchpad works fine on the Windows. Strangely, if I reboot from Windows it works on Ubuntu as well. Then I turn off the machine, and then boot on ubuntu, then it stops working.
  i.e. if the previous boot was directed to Windows ==> The touchpad is recognized and works fine.
  if the previous boot was directed to Ubuntu ==> the touchpad is not recognized.

  I installed the driver (psmouse-elantech-x551c.tar.gz) but still the
  touchpad is not recognized.
