No TrackPoint scroll

[Isaac Salgueiro]

TrackPoint's middle button is not detected, so TrackPoint scroll didn't work either.

"Button Unknown" seems to be the TrackPoint itself.

This is a ThinkPad E470 and a 16.04 fully updated fresh install.

Tried with xserver-xorg-input-libinput-hwe-16.04 0.19.0-1ubuntu0.1. No middle button either.

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

[User One (userone470)]

I found that

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

enables the middle button, i.e. pasting works. BUT scrolling with touchpad or middle button + trackpoint does not work.

[User One (userone470)]

Same for proto=exps and proto=bare.

dmesg also tells us that psmouse failed to retrieve extended button data:

[...]
[ 5276.513617] psmouse serio7: trackpoint: failed to get extended button data
[ 5280.377455] psmouse serio7: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0
[...]

Can confirm that reloading psmouse module enables middle button, but for me after reloading psmouse module xinput only shows "PS/2 Synaptics TouchPad" and no "TPPS/2 IBM TrackPoint". Passing "proto=imps" as an option to psmouse in /etc/modules makes no change, after rebooting no middle button is detected.

I also have the "failed to get extended button data" message in /var/log/syslog

[User One (userone470)]

As described here [1] installing xserver-xorg-input-libinput-hwe-16.04 and reloading psmouse with proto=imps enables the middle button. Also scrolling with middle button + trackpoint works, but two-finger scrolling using the touchpad does not work. It would be nice to be able to use touchpad and trackpoint.

The same on 17.04 and ThinkPad E570. After this "sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps" the touchpas works but with libinput the middle button is dead.

[Anthony Wong (anthonywong)]

If you have Thinkpad E470, please try this DKMS package, E570 may need another solution, you are welcome to try but it may not work. If it works, we will try to upstream it.

[Isaac Salgueiro (isalgueiro)]

Thanks @anthonywong! I can confirm that after installing oem-touchpad-psmouse-1615937-dkms_1.0sutton1_all.deb package the middle button is detected in my E470 and Trackpad scrolling works now like any standard mouse wheel scroll.

I'm currently running 16.04.3 LTS (Neon 5.8 actually). Here's the xinput output after installing this DKMS package:

I just found this in the apt-get upgrade output:

Good news! Module version for sermouse.ko
exactly matches what is already found in kernel 4.13.0-16-generic.
DKMS will not replace this module.
You may override by specifying --force.

I can confirm that oem-touchpad-psmouse-1615937-dkms_1.0sutton1_all.deb is no longer needed and this issue is resolved in 4.13.0.16.23 hwe.

I still cant use middle button scrolling I even have installed the DKMS package and still it is not working.
