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.
