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.

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).

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).

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.

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

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.

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!

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.

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

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.

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.

Status update:
The kernel patches are now in Dmitry's branch and queued for 4.0

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.

I have a T450s and ubuntu 14.04 and tried kernel 3.19.0-11.11 and 3.19.0-12.12. I experienced the same strange issues wit wifi in the sense that it just didn't exist any more.

When I tried kernel 3.19, I also lost wifi. Using the iwlwifi firmware
from the 3.18 kernel fixed it, though.

@ Adam Olsen
how do you use the iwlwifi firmware from the 3.18 kernel? A quick search didn't give me any hints.

I am on X1 Carbon. I have tried kernel 3.19.3. The button issue is not fixed and I lost wifi.

My current kernel is 3.16.0, and the only issue is the touchpad buttons.

Buttons do work. Wifi initially did not work.
I had to manually download the appropriate .ucode file from https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi and copy it into my /lib/firmware folder.

VirtualBox seems to be a different story. Try adding "nosmap" to the kernel command line (see http://askubuntu.com/questions/581301/virtualbox-stuck-on-starting-virtual-machine ), that worked for me.

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.

Thanks!

Timo Aaltonen (tjaalton) wrote :

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...

For anyone, who cannot/doesn't want to wait month or two more, I did a quick backport of the 4.0 driver for 3.16 kernel (https://github.com/andree182/psmouse-dkms-alpsv7 , just call install.sh). Both trackpoint and touchpad appears to work fine. Hopefully this will work out of box later even with the official kernel...
