Title:
  Elantech touchpad not detected

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am using a Gigabyte U24T laptop with a touchpad. My touchpad works
  on some boots but on others it goes missing without a trace. I have
  been told to look for it with 'xinput --list' and 'cat
  /proc/bus/input/devices' but neither of these return any touchpad
  related items. I have attached a link the output of the previously
  mentioned commands in their respective order.

  http://pastebin.com/ZVt487wB
  http://pastebin.com/qjjeq4BE

  I can't give any information on the touchpad as it is currently in a
  non-working state, however, this may or may not change after a reboot.
  I believe it is an ElanTech touchpad.

  Not sure what else I can do with this problem, it really annoying to
  randomly loose mouse functionality sometimes. I don't think it is a
  problem with the device itself as there have never been any problems
  in my Windows 8 install. They are boot using different boot methods,
  Linux is using GRUB through BIOS and Windows in using UEFI.

  Hope this helps.
