First off, I'm new around here, so my apologies in advance if this is
the wrong list or I've formatted something incorrectly.
I've recently installed OpenBSD 6.3 on my Thinkpad X220. I'm happy to
report that almost everything seems to work the way it should
(suspend/resume, wireless, volume controls, etc.). However, I've been
having some difficulty with the TrackPoint.
The TrackPoint works fine as a pointing device, however the "WS
Pointer Wheel Emulation" emulation feature is not working. For those
unfamiliar, this allows the middle mouse button to be held down, and
while it is held, the TrackPoint can be used to scroll vertically or
horizontally.
After conducting some research, I have written the following script to
set the appropriate xinput properties to properly enable the pointer
wheel emulation functionality:
#!/bin/sh
xinput set-prop /dev/wsmouse "WS Pointer Wheel Emulation" 1
xinput set-prop /dev/wsmouse "WS Pointer Wheel Emulation Button" 2
xinput set-prop /dev/wsmouse "WS Pointer Wheel Emulation Axes" 6 7 4 5
xinput set-prop /dev/wsmouse "WS Pointer Wheel Emulation Timeout" 500
xinput set-prop /dev/wsmouse "WS Pointer Wheel Emulation Inertia" 20
I have tried many different variations on the input parameters.
One interesting behavior I have discovered is that if I set the
emulation axes to "4 5 0 0" then I can scroll up and down by moving
the track point left or right by holding the middle mouse button.
However, when I use "6 7 4 5" or "0 0 4 5", the up and down scrolling
generally does not work at all (occasionally jumping in the direction
the trackpoint was pushed).
I have spent several days troubleshooting this issue and haven't had
any luck. I think this may be a bug, but I wanted to see if anyone
else had similar issues and knew of a solution before submitting a bug
report. I am under the impression that this list does not permit
attachments, so I will refrain from attaching the full output of dmesg
and other long logs, but I will include the output of some
commands that I think might be relevant.
Finally, I tried digging into some of the source code for Xenocara and
the wsmouse drive. Unfortunately, my knowledge of OpenBSD and Xorg are
insufficient to draw any useful conclusions. However, I think the
following files may be relevant / a good starting point for someone
more knowledgeable than I:
* xenocara/driver/xf86-input-ws/include/ws-properties.h
* xenocara/driver/xf86-input-ws/src/emuwheel.c
I would really appreciate any suggestions to troubleshoot further.
