    Input: elantech - v4 is a clickpad, with only one button

    BugLink: http://bugs.launchpad.net/bugs/1033568

    Add pointer and buttonpad properties for v4 hardware.

    Also, Jachiet reported that on Asus UX31, right button has no effect.
    It turns out v4 has only one button, the right-button effect is
    implemented with software when Windows driver is installed, or in
    firmware when touchpad is in relative mode. So remove BTN_RIGHT
    while at it.

It seems to be intentional to remove the right button.

And read the first bad commit more carefully,
it says elan v4 clickpad has only one button, it's not true for Dell V 5460.
I'm going to generate a new patch for it and discuss with upstream maintainer.

Hello Christopher,
Base on these comments, I don't think it's BIOS related.

And... indeed, upgrade BIOS to A07(09/04/2013) does not help at all.

Po-Hsu Lin, thank you for updating your BIOS. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

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

    There are several bug reports for this, ie:

    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.

I had the same problem on Dell Vostro 5470. Since I'm a fedora user, I opened a bug on Red Hat bugzilla and the problem has been solved by Hans from Red Hat. The patch has been applied. Here is the commit:

Still affecting Trusty

@anto, sorry your solution doesn't work for me, maybe I missed something?
@Elder, yes, the description in that commit exactly describes what happened, two buttons touchpad detected as a clickpad.

Another way to verify this hardware is to press and hold the left button, you will hear a "click"
And press the right button, you will hear another "click"
But only the left button is working, if you put a finger on the right button (don't press it), and click on the left button, it will be detected as a right click, just an expected behavior for clickpads.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
