Trackpoint horizontal scrolling not working and other trouble
by kaott from LinuxQuestions.org on (#57GR7)
Howdy,
I have a Trackpoint Keyboard II and I am running Slackware-current. I can not seem to get the horizontal scrolling (hold down middle click + move trackpoint around) to work. Also, it appears to generate an unpress event when I start to scroll, thus it will paste the contents of the clipboard when able.
The vertical scroll mostly works properly. I have googled around and done some debugging, but nothing obvious jumped out at me. Looking at output of xev and libinput debug-events, it appears there are no horizontal scrolling events appearing.
Here is the output of xinput list-props for the device.
Code:$ xinput list-props 10

Here is some snipped output from xev and libinput debug-events

event3 POINTER_AXIS +7.884s vert 15.00/1* horiz 0.00/0 (wheel)The above output is showing the events generated when scrolling vertically, but none are generated when trying to scroll horizontally. It also shows the middle button event being released, even though I have not let off the key.
I looked around to see if this was an issue with libinput but didn't find anything. I have tried some older kernels to see if that changed anything (I don't recall it ever working on older kernels, but it seemed worth a shot), but nothing newer than 5.4.61.
Does anyone have any insights on what is going on here, or any suggestions on what to do/try?
EDIT:
Forgot to mention that I had also tried switching back to evdev with negative effect as it now seemed that keypress events weren't being registered/dropped.
Thanks,
