The only explanation I can find for this bug is a BIOS flaw. I would try
to update the BIOS from the manufacturer website and see if the bug goes
away.

After doing so, or after finding that updating is not possible, please
set this bug status back to "confirmed". Good luck because BIOS are a
messy world!

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  Elantech touchpad not recognized

Status in linux package in Ubuntu:
  Incomplete

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.
