Title:
  Elantech touchpads not fully supported for some Gigabyte laptops

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  This bug report is in addition to
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442 - the
  fixes suggested there (which work for others) have been tried but do
  not work for a small subset of laptops, particularly the Gigabyte
  U2442 series.

  Description of the situation for my Gigabyte U2442V most recently
  running 3.11.0-12-generic on Linux Mint.

  I tried the updated module mentioned in the above bug report (1166442). It compiles and it detects an Elantech trackpad of *indeterminate version*.  I get this in dmesg:
  [859697.496141] psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x450f01)
  [859697.526011] psmouse serio1: elantech: Synaptics capabilities query result 0x58, 0x17, 0x0c.
  [859697.765917] psmouse serio1: elantech: retrying ps2 command 0x0b (2).
  [859698.470556] psmouse serio1: elantech: retrying ps2 command 0x0b (1).

  I get no Synaptics driver functionality, and only basic touchpad
  behaviour (motion and tap-to-click for left click, no scroll or
  disabling the pad when typing, etc.).

  It seems I don't have a v9 or v10 trackpad, I've never been able to
  get a definitive indication of which version I have got.

  The only thing that has remedied this problem for me in the past was
  the one described in the original bug report (for elantech-v6 -
  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
  intel/+bug/681904/comments/64)... but it no longer applies to newer
  kernels...

  With the 3.11.0-12-generic kernel, my Touchpad *is* detected, i.e. xinput shows:
    ↳ PS/2 Elantech Touchpad id=16 [slave pointer (2)]
  and dmesg shows:
   input: PS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input14

  There are no useful touchpads settings evident in the normal Cinnamon
  settings utility (gnome-control-center -> Mouse & Touchpads).  I see a
  touchpad settings option with the "gpointing-device-settings" app and
  I can turn on vertical and horizontal scrolling in the interface, but
  doing so does not in any way affect that actual touchpad behaviour.

  I've also tried installing the elantech-v7 module via dkms (see http://ubuntuforums.org/showthread.php?t=2111236&p=12850603#post12850603) and it compiles, but it too fails to provide the desired functionality.
