@PHLin
Can you give the mainline kernel, e.g. http://kernel.ubuntu.com/~kernel-
ppa/mainline/daily/2014-01-23-trusty/, a try? There is a patch in
current mainline that probably fixes this bug.

Input: elantech - improve clickpad detection
The current assumption in the elantech driver that hw version 3 touchpads
are never clickpads and hw version 4 touchpads are always clickpads is
wrong.
There are several bug reports for this, ie:
https://bugzilla.redhat.com/show_bug.cgi?id=1030802
http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux
I've spend a couple of hours wading through various bugzillas, launchpads
and forum posts to create a list of fw-versions and capabilities for
different laptop models to find a good method to differentiate between
clickpads and versions with separate hardware buttons.
Which shows that a device being a clickpad is reliable indicated by bit 12
being set in the fw_version. I've included the gathered list inside the
driver, so that we've this info at hand if we need to revisit this later.
Firmware of this touchpad is 0x461f04, so bit 12 is 1.
