Hi, I have an old Thinkpad T60 running Debian unstable, and on latest update the trackpoint accelaration etc got really fast. So fast that it's to me unusable. Touchpad is fine. I tried to modify the acceleration etc settings in Xfce mouse dialog and with xinput command line tool but I can't make it slow anymore. If I downgrade to libinput version 1.8.3 it works well again. How to make Thinkpad trackpoint slower with libinput 1.9.2? "xinput list-props" shows exact same settings with libinput 1.8.3 and 1.9.2 so I'm lost what more can I tune. # xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=10 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=11 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=12 [slave keyboard (3)] #

On #wayland irc channel I got the instructions to run: # libinput measure trackpoint-range This tool measures the commonly used pressure range of the trackpoint. Push the trackpoint: - Four times around the screen edges - From the top left to the bottom right and back, twice - From the top right to the bottom left and back, twice A minimum of 1000 events for each axis is required Movements should emulate fast pointer movement on the screen but not use excessive pressure that would not be used during day-to-day movement. For best results, run this tool several times to get an idea of the common range.

The libinput Accel Speed property still shows 0, have you tried lowering it? It's a double in the range [-1, 1] for slowest/fastest. The range of the trackpoint seems to fall into the default of 20, so whatever that trackpoint is doing, it's different to the laptops the current accel method was designed on. Not sure how to debug this, tbh.
My TrackPoint also started to behave very differently after installing libinput 1.9.3. I'm using a ThinkPad X121e running Arch Linux. Using sysfs to change the sensitivity worked. Locate the files we can change (command from <https://gist.github.com/noromanba/11261595>): $ find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint | sed 's/\/input\/input[0-9]*\/name$//' /sys/devices/platform/i8042/serio4/serio5 I checked whether the upgrade changed any values at this point, which it didn't: # for f in /sys/devices/platform/i8042/serio4/serio5/*; do [[ -f $f ]] && echo "$f" && cat "$f"; done > new-values.txt # pacman -U /var/cache/pacman/pkg/libinput-1.8.3-1-x86_64.pkg.tar.xz # downgrade libinput # systemctl reboot # for f in /sys/devices/platform/i8042/serio4/serio5/*; do [[ -f $f ]] && echo "$f" && cat "$f"; done > old-values.txt $ diff -s new-values.txt old-values.txt Files old-values.txt and new-values.txt are identical In the end I changed /sys/devices/platform/i8042/serio4/serio5/sensitivity to a lower value: $ cat /sys/devices/platform/i8042/serio4/serio5/{speed,sensitivity} 97 128 $ echo 100 | sudo tee /sys/devices/platform/i8042/serio4/serio5/sensitivity
fwiw, I never got an answer to "The libinput Accel Speed property still shows 0, have you tried lowering it? It's a double in the range [-1, 1] for slowest/fastest."
Also, I'd need the libinput debug-events --verbose output, the initial output of it at least before any motion events (or with, doesn't matter)
