I received a Lenovo X1 Carbon 3rd generation today, the one with the
resurrection of the physical Trackpoint buttons. However, there is
some broken behavior related to those much loved buttons on this laptop
running an up-to-date Fedora 21.

The clickpad buttons seem to work fine, however I would like to achieve
a configuration that disables the touchpad and only use the Trackpoint
and the physical buttons as I have on all my Thinkpads in the past.
There is an option in the BIOS to disable the touchpad, but it seems to
be completely ignored under Linux; with it set to off in the BIOS, the
touchpad is still fully functional. This is likely related to the fact
that the physical buttons generate events on the touchpad's event device
(/dev/input/event4 in this case) and not for the Trackpoint's event
device (/dev/input/event12), so the device can't really be disabled.

So here are the various scenarios regarding the physical buttons and how
they are failing at the moment:

- Dragging does not work at all with the physical left button with either
the evdev or synaptics driver. Dragging with the clickpad's left button
is fine.

- Middle click does not register at all (from viewing evtest output), which
I assume means it's an issue at the kernel layer not registering the event.
Neither the physical buttons or the clickpad generate a middle click event
using either the evdev or synaptics drivers.

- With the synaptics driver, the buttons are picked up as up/down buttons.
Setting UpDownScrolling=off changes the behavior as described in the man
page (double-click/button 2). Using xinput, I can force the right-button
to behave correctly, but the left-button will not change its behavior (it
is always a double-click). This makes it unusable with the synaptics
driver.

Here is the evemu-record output. The BTN_0 and BTN_1 events are from the left and right physical buttons. The BTN_LEFT events are from the clickpad. No events are generated using the middle physical button.

actually, can you attach the dmesg output here too please (as attachment). and while you're at it, please run libevdev's touchpad-edge-detector and see if the min/max of the touchpad matches what it claims. Thanks

[Peter Hutterer (peter-hutterer)]

well, at least that's some good news. the axis range is correct enough, but we need to take LEN0048 out of the INPUT_PROP_TOPBUTTONPAD list in the kernel. which should be fine, doesn't look like it's re-used (I think).

[Larry Hastings (larry-hastings)]

I'm experiencing the issue too, under Ubuntu 14.10. I'm happy to install something bleeding-edge on the laptop for experimentation; it's not like the laptop is terribly useful without working mouse buttons.

Given that middle-mouse button scrolling is implemented in the trackpoint driver, and the middle mouse button (when it works) will be firing in the synaptics driver, I'm guessing that even when the buttons are fixed, middle-mouse button scrolling will still be broken. Just like the 2014 refresh Lenovo laptops without hardware mouse buttons (see bug 70780).

[Peter Hutterer (peter-hutterer)]

Note that this bug currently affects upstream (kernel, libinput and xorg) and all distributions. In the interest of keeping the bug useful, please only CC yourself, do not comment that you have the same issue. We know you do.

We'll post updates once we figured out how to fix all this, please keep the noise on this bug to a minimum.

[Msw-c (msw-c)]

As a workaround you can force the psmouse driver to use the imps protocol. When using the imps protocol the buttons are mapped correctly. Further, the BIOS option to disable the touchpad is honored.

Of course you can't use the fancy Synaptic touchpad features, but I have no use for them anyway.

Exactly the configuration I wanted! Thanks for the tip Matt.

For those on Fedora, psmouse built in and not a module, so the approach is slightly different. You'll need to set it in /etc/default/grub and then update your grub config.

# grep psmouse /etc/default/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=vg00/swap rd.lvm.lv=vg00/root quiet psmouse.proto=imps"

# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Touchpad buttons could not work occurred on a lot of Lenovo platforms after 2014 year. Please refer to <https://bugs.launchpad.net/sutton/+bug/1363815>

[Gabriel Zhi Chen (gabrielzchen)]

HWE team made a workaround here, but the behaviour of the buttons is different from normal. And the kdms will not be maintained. We need a Synaptics official driver.

[Christopher M. Penalver (penalvch)]

Gabriel Zhi Chen / Liming Wang, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to 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 by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

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.

[Yung Shen (kaxing)]

Hey @Gabriel,

Can you also verify this issue with utopic(3.16) kernel?

You can enable proposed-trusty repository in Software Center -> Edit... -> Software Sources.. -> In "Updates" Tab

After update the database, then install this pacakge, "linux-image-generic-lts-utopic"

To see if this issue also exist.

Thank you!

[Peter Hutterer (peter-hutterer)]

Status update:
* missing middle button is a kernel bug
* touchpad marked with INPUT_PROP_TOPBUTTONPAD is a kernel bug
* handling the trackpoint buttons through the touchpad device will require userspace fixes, some combination of udev rules/hwdb and fixes in synaptics and libinput. Theoretically evdev too, though the touchpad parts in evdev are mostly untested.

Patches will be coming in the next couple of days, we're trying to get everything in place first so we can actually test all bits against each other.

I expect that the final outcome with synaptics will be similar to the T440: everything works except for middle button scrolling. libinput will just work fine.

Hi Peter,
I was finally able to get some time to recompile the various RPMs for F21 with the patches applied and test out the whole stack. I used the first iteration of the kernel patches posted to the mailing list, but it looks like those might change a little bit; either way, they work even if they're not the final version.

Aside from the issue below, the trackpoint buttons work as expected. Setting TouchpadOff=1 disables the touchpad for moving the cursor, but the clickpad buttons are still enabled. This seems to be the intended behavior based on synaptics(4), so I can live with it.

The X11 stack seems to work fine, but the hwdb entry is not tagging the device properly. By removing the "MatchTag" option from the xorg.conf.d file, everything worked as expected. For the hwdb update, I dropped the file in place and updated. Here is verification that the hwdb piece is in place but not working:

[root@x1 ~]# grep -v ^# /lib/udev/hwdb.d/70-touchpad.hwdb; udevadm trigger /dev/input/event5; udevadm info /dev/input/event5

Scratch that. I pulled in xorg-x11-drv-synaptics-1.8.1-2.fc21.x86_64 (http://koji.fedoraproject.org/koji/buildinfo?buildID=608494) which does not correctly include the xorg and udev configurations. Manually dropping those in place makes the whole set of proposed patches work.

[Peter Hutterer (peter-hutterer)]

the hwdb doesn't have effect on the synaptics driver bits, but if the files aren't installed correctly that's a fedora bug, please file it there and assign it to me.

Note you also need to udevadm control --reload-rules to make the hwdb work (and drop the matching 70-touchpad.rules file in place too).

Yep. You have a bug waiting for you on rhbz with the fixes attached.

Thanks for all the work on this Peter.

[Ben Hearsum (bhearsum)]

I'm hitting this on Ubuntu 14.10 as well. Out of the box, the left button generates button 4 events, the right button generates button 5 events, and the middle button generates nothing at all.

The situation improves a little bit by setting UpDownScrolling=0 ("synclient UpDownScrolling=0"), after which the left button generates a double left click and the right button generates a button 2 event. However, both buttons generates the press _and_release events right away - and no event is generated when the physical button is released.

[Launchpad Janitor (janitor)]

This bug was fixed in the package systemd - 219-1ubuntu1

---------------
systemd (219-1ubuntu1) vivid; urgency=medium

  * Merge with Debian experimental. Remaining Ubuntu changes:
    - Hack to support system-image read-only /etc, and modify files in
      /etc/writable/ instead.
    - Keep our much simpler udev maintainer scripts (all platforms must
      support udev, no debconf).
    - initramfs init-top: Drop $ROOTDELAY, we do that in a more sensible way
      with wait-for-root. Will get applicable to Debian once Debian gets
      wait-for-root in initramfs-tools.
    - initramfs init-bottom: If LVM is installed, settle udev,
      otherwise we get missing LV symlinks. Workaround for LP #1185394.
    - Add debian/udev.lvm2.init: Dummy SysV init script to satisfy insserv
      dependencies to "lvm2" which is handled with udev rules in Ubuntu.
    - Provide shutdown fallback for upstart. (LP: #1370329)
    - debian/extra/ifup@.service: Additionally run for "auto" class. We don't
      really support "allow-hotplug" in Ubuntu at the moment, so we need to
      deal with "auto" devices appearing after "/etc/init.d/networking start"
      already ran. (LP: #1374521) Also, check if devices are actually defined
      in /etc/network/interfaces as we don't use Debian's net.agent.
    - ifup@.service: Drop dependency on networking.service (i. e.
      /etc/init.d/networking), and merely ensure that /run/network exists.
      This avoids unnecessary dependencies/waiting during boot and dependency
      cycles if hooks wait for other interfaces to come up (like ifenslave
      with bonding interfaces). (LP: #1414544)
    - Add Get-RTC-is-in-local-time-setting-from-etc-default-rc.patch: In
      Ubuntu we currently keep the setting whether the RTC is in local or UTC
      time in /etc/default/rcS "UTC=yes|no", instead of /etc/adjtime.
      (LP: #1377258)
    - Put session scopes into all cgroup controllers. This makes unprivileged
      user LXC containers work under systemd. (LP: #1346734)
    - Add systemd-fsckd multiplexer and feed its output to plymouth. This
      provides an aggregate progress report of running file system checks and
      also allows cancelling them with ^C.
      (LP: #1316796; Closes: #775093, #758902)
    - Lower Breaks: to plymouth version which has the udev inotify fix in
      Ubuntu.
    - Lower libappamor1 dep to the Ubuntu version where it moved to /lib.
    - Make failure of boot-and-services NSpawn.test_boot non-fatal for now.
      This currently fails when being triggered by Jenkins, but is totally
      unreproducible when running this manually on the exact same machine.

    Upgrade fixes, keep until 16.04 LTS release:
    - systemd Conflicts/Replaces/Provides systemd-services.
    - Remove obsolete systemd-logind upstart job.
    - Clean up obsolete /etc/udev/rules.d/README.

systemd (219-2) UNRELEASED; urgency=medium

  * Fix UTF-16 to UTF-8 conversion on big-endian machines. (Closes: #778654)
  * Disable new new test-sigbus, it fails on some buildds due to too old
    kernels. (part of #778654)
  * debian/README.Debian: Drop setfacl call for /var/log/journal, this is now
    done automatically by tmpfiles...

Yep, we know about it. See https://patchwork.kernel.org/patch/5820871/

BTW, with latest kernel submission, there should not be needed to patch libinput & synaptics. It's just been sitting on the list for a while now.

[Timo Aaltonen (tjaalton)]

[seth goldstein (seth-o)]

I have a thinkpad T450s. The buttons do not work on it. How can I help?

[LEVIS Cyril (atlas95)]

Hi,

On the new T450s too we seem to have the same problem (same touchpad I think), I must use psmouse to get my touchpad working for the moment.

PNPID is :
cat /sys/devices/platform/i8042/serio1/firmware_id
PNP: LEN200f PNP0f13

Do you need more information?

Regards,

[Cs-gon (cs-gon)]

Hi,

we have the same issue regarding the firmware ID, as other reported earlier. We have new T550 systems, which have the following firmware ID:

# cat /sys/devices/platform/i8042/serio1/firmware_id
PNP: LEN002c PNP0f13

When adding a corresponding udev rule for this firmware ID to set the udev tag, the Xorg synaptics driver get configured correctly, and the buttons behave as they should.

[Eazyvg (eazyvg)]

[Peter Hutterer (peter-hutterer)]

Status update:
The kernel patches are now in Dmitry's branch and queued for 4.0
https://git.kernel.org/cgit/linux/kernel/git/dtor/input.git/commit/?h=for-linus&id=6067fe5e0bf29f525561c8281d01011cfc9ebbd4

There will _not_ be a patch to the synaptics driver (or libinput). The kernel patches re-route the trackstrick buttons correctly so we don't need userspace to fix this up any. The commit that was already on the branch has been reverted, see:
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?id=5378a020a003cbdfa565d43c9e01997b570059c9

For distributions: if you are partially backporting Benjamin's kernel patches make sure you either re-instate that synaptics commit or backport the button re-routing patches.

[flickerfly (josiah-ritchie)]

Looks like systemd 219-1ubuntu1 is required to resolve this bug, but 14.10 latest systemd is 208-8ubuntu8.2. What is the best way to get this enhancement applied?

[klinge (rosgnilk)]

Hi

I have the same problem on a T450s running ubuntu 14.04. i installed kernel 3.17 and 4.0rc4 nothing changed.

The fancy stuff is not important for me but if there is a solution could someone please explain stepp by stepp what to do. Ideal i want to switch off the trackpad an use only the trackpoint with its tree buttons.

[seth goldstein (seth-u)]

The following temporary hack will enable the trackpoint buttons and if the trackpad is disabled in the bios will also disable the trackpad. (I don't remember where I saw this, sorry for non-attribution)

sudo modprobe -rv psmouse; sudo modprobe -v psmouse proto=imps

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Timo Aaltonen (tjaalton)]

[Timo Aaltonen (tjaalton)]

I've put an utopic kernel build here, can be tested on trusty too:

http://people.canonical.com/~tjaalton/utopic-fix/

[Timo Aaltonen (tjaalton)]

It includes the upstream commits plus BDW i915 bugfixes for bug 1434514

[GH (chili-g)]

@Timo thanks for the build but it hangs booting for me on a t450s on 14.04.2.
Just hangs on a gray screen after I pick Ubuntu from the boot menu.

[GH (chili-g)]

Sorry for the total noob question - I'm unclear on the terminology but would like to test this. @Julian, does lts-vivid mean it's a 3.19 kernel that would work on 14.04.2 - or is it just vivid - maybe available in the Beta 2 today?

[GH (chili-g)]

@Timo fwiw, it hangs on "Unsupported brightness interface, please contact <email address hidden>".
This is a T450s on 14.04.2 with the kernel build you posted.

[Timo Aaltonen (tjaalton)]

did you install both packages?

[Julian (jupian)]

@chili-g I wanted to point out that this bug also affects the latest 3.19.0-10 kernel which comes with vivid.
A was also unclear about the terminology and i found out that it is always assumed that a bug affects the latest version of ubuntu. Because of that i reverted my change ;)

[GH (chili-g)]

@Timo, yes I installed both packages. I went to 15.04 beta 2 yesterday and so far haven't seen any graphics issues, but the touchpad issue exists (as @Julian indicates). For now I'll probably stick with that and one of the touchpad workarounds I can live with for now, under the assumption that 15.04 is the most likely to see the fix first.

[Timo Aaltonen (tjaalton)]

you can find a preliminary 3.19.0-11 here, which includes the patches:

https://launchpad.net/~ubuntu-kernel-test/+archive/ubuntu/devel

[GH (chili-g)]

@Timo, That latest patch is very promising! Touchpad is working perfectly! 2-finger scrolls, scroll button, touchpointer, etc.
Strangely, on my t450s, the wifi and my external display don't work now though. It doesn't recognize that I have an external display attached (in the gnome display settings UI at least). Rebooting back to 3.19.0-10 and they are working again.
I didn't notice an obvious errors in syslog, but if there's something I can check or post to help test let me know.
Thanks again for the effort.

if you have a hybrid machine using nvidia, you'd need headers too for the nvidia dkms build.. there should be no other reason for the breakage though

mainline kernel 4.0.0-040000rc7-generic fixed trackpoint issues for me. (on Ubuntu 12.04 LTS)

Separate issue but I also use an external "Lenovo ThinkPad Compact USB Keyboard with TrackPoint" and middle scrolling did not work out-of-the-box . set-prop "Evdev Wheel Emulation Button" to 4 fixed this. The integrated keyboard was differently set to 2.

I did not directly set this but changed the MatchProduct in /usr/share/X11/xorg.conf.d/11-evdev-trackpoint.conf to be more specific "IBM TrackPoint|DualPoint Stick" and the non-matched Compact Trackpoint Keyboard fallback defaulted to "4" for EmulateWheelButton.

Is this kernel patch going to be backported to Trusty LTS? If so, will that be sooner or later? I have 24 machines to set up, and 15.04 isn't a supported config at my workplace because they only support LTS releases.

It's not one patch but a series of seven patches which depend on other functionality to be backported..

The prep patches have been accepted to the next 3.13 point release which will be released next week. Then that will be merged with the trusty git tree, and the actual patches can be added. The result will be pushed to proposed by first week of May, and it'll take 2-3 weeks from that to reach -updates...

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

i have a lenovo t450s and following kernel:
3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
now the trackpad buttons working well

[Timo Aaltonen (tjaalton)]

thanks for testing, adjusted the tag

[Sven Mueller (smu-u)]

Actually, Markus tested Trusty, not Utopic:
3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64
14.04.1 is the Trusty version, not Utopic. Therefor adding verification-needed-utopic back and adding verification-done-trusty.

[Timo Aaltonen (tjaalton)]

wrong, it's identical to the kernel in utopic... trusty verification needs to be done with stock trusty kernel

[klinge (rosgnilk)]

I tested trusty 3.16.0-38.52~14.04.1. The buttons work (but I prefere their behoviour with: modprobe -rv psmouse; modprobe -v psmouse proto=imps). Graphic issues still exist. So I go back to mainline kernel.

[Liming Wang (wangliming)]

I tested trusty with the -proposed kernel 3.13.0-53, the buttons of touchpad work well.
