Bug Description

I have a Lenovo ThinkPad Compact USB Keyboard with TrackPoint - this is an external USB keyboard with integrated TrackPoint that is based on the keyboard from the Thinkpad X230/T430/T530.

Lenovo part number is: 0B47190

Vertical scrolling works fine out of the box on Ubuntu 14.04 (fully updated), but horizontal scrolling does not work.

I have it connected to a Thinkpad X200, also with integrated Trackpoint, where horizontal works fine.

If I run xev, vertical scrolling up / down outputs button 4 / 5 as expected, but horizontal scroll has no output.

I have an open thread about it here:

Here is an Amazon reviewer on Archlinux (likely more knowledgeable than me) with the same issue:

On a Windows machine horizontal scroll worked fine using the same device.

Could you check the output of "xinput list-props 14"? (change 14 to match whatever the ID should be from the pointer section. 14 is based on your xinput output above).

By the way, I use this config with my Trackpoint:

hyperair@thinkpwn:/etc/X11/xorg.conf.d% cat 50-trackpoint-acceleration.conf
Section "InputClass"
        Identifier "trackpoint"
        MatchProduct "TPPS/2 IBM TrackPoint"
        Option "AccelerationProfile" "2"
        Option "AccelerationNumerator" "25"
        Option "AccelerationDenominator" "10"
        Option "VertScrollDelta" "8"
        Option "HorizScrollDelta" "8"

Section "InputClass"
        Identifier "trackpoint-usb"
        MatchProduct "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint"

        Option "AccelerationNumerator" "25"
        Option "AccelerationDenominator" "10"
        Option "VertScrollDelta" "8"
        Option "HorizScrollDelta" "8"

Note that HorizScrollDelta is set in this.

Since upgrading to Xubuntu 15.10, neither vertical nor horizontal scrolling work with this keyboard.

Any updates regarding this bug? I'm still experiencing this on 15.10 (Unity). Can we at least get is assigned?

This is a great keyboard in combination with a Thinkpad laptop, and it's a real shame that neither horizontal nor vertical scrolling work in 15.10 anymore.

Does anyone have a fix of any kind for this?

I'm on Kubuntu 16.04.1 on 4.4.0-51.72 kernel. I noticed after a kernel update that it was working both horizontally and vertically with the trackpoint on the Lenovo Thinkpad USB keyboard model number KU-1255. I figured this group had already been notified.

If others can confirm, I think this bug can be marked as FIXED.

In case anyone is curious. I'm on xserver-xorg-input-evdev 1:2.10.1-1ubuntu2

Confirmed - horizontal and vertical scrolling is working again in 16.04.

Thanks guys!

I experienced the same bug. I could only scroll horizontally but not vertically. However, when I connected the keyboard over USB 3 and not USB 2 everything worked as expected.
