Middle button of trackpoint doesn't work

    Input: trackpoint - add new trackpoint firmware ID

    Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits
    are indicated as TP. Change the constant to bitwise values.

    This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead
    of it being identified as "PS/2 Generic Mouse".

The 1st patch was already sent to stable kernel, so don't need to merge to Ubuntu kernel.

    Input: trackpoint - assume 3 buttons when buttons detection fails

    Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
    this makes the middle button of the trackpoint to not being recogized.
    As I don't believe there is any trackpoint with less than 3 buttons this
    patch just assumes three buttons when the extended button information
    read fails.

This 2nd need to be merged to ubuntu kernel.

1st patch is included in stable kernel v4.4.85

I don't get it. Is this patch supposed to make things better? It just made my button *not work*. Is there a patch for the patch on the way, or do I need to rollback and recompile things in order to get rid of your patch?

2 patches above are needed, could you confirm the 2 patches are included in your kernel?

And how your button can not work? please upload the dmesg.

To be honest I don't know. I'm on Arch Linux, and found that when upgrading to 4.12.10 the middle mouse button on my Lenovo ThinkPad X1 Carbon Gen5 stopped working. I looked into [the changelog](https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.12.10) and found your patch which I naively assumed to be the cause of my newfound issue.

I'm currently on 4.12.10-1-ARCH, but I don't know from the top of my head to double check exactly what's included there. If you can't tell from only the version number, please let me know and I'll have to figure that out some time next week.

Andreas,

Maybe just revert the patch then build a new kernel to test it?

Sure, I might have time for that within the next week or next few weeks at least, but not right now. I know I can fix it if I put in some effort. I'm mostly annoyed that there are broken stuff in the stable kernel.

It seems like I'm not the only one with this problem: https://www.reddit.com/r/LinuxOnThinkpads/comments/6ydvly/did_your_middle_mouse_button_just_stop_working/

Please try 4.13.0 kernel, not stable branch, this will make middle button work.

Send 2nd patch to <email address hidden>.
Waiting for maintainer's feedback.

Works again for me since 4.12.12-1

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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Tested on E470 with Xenial 4.4.0.97-120 kernel, works fine.

The first patch in #1 is still missing in Zesty kernel.
I will send it to zesty kernel.

Ubuntu Artful needs the 2nd patch in comment #3 too.
Please apply it on artful kernel 4.13

Quoted from Seth:

"
Artful is based on 4.13 and the patch went upstream in 4.13-rc6, so
artful does have the patch already.

"

Double checked Artful OK.

This bug was nominated against a series that is no longer supported, ie artful. The bug task representing the artful nomination is being closed as Won't Fix.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This issue was fixed in the upstream 4.13 kernel, so the devel release (and bionic) of ubuntu are no longer affected, closing.
