[Bug 1272777] Re: Elantech touchpads not fully supported for some Gigabyte laptops

 

Mmmm, so that has to be some other library at this point I guess; it does not make much sense.
My dmesg | egrep psmouse:
[    3.394141] psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x450f01)
[    3.420521] psmouse serio1: elantech: Synaptics capabilities query result 0x58, 0x17, 0x0c.

So it is that ps2 command failed that is the culprit...

What ubuntu are you running?
I'm on lubuntu 64 bit trusty (14.04)

xinput version 1.6.1
XI version on server: 2.3

Not sure what you can find out with that... sorry.

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.
