How can one change trackpoint scrolling speed? It's way to slow (T480s + Ubuntu 18.04). Mouse speed setting seems working fine and mouse speed is suitable but it doesn't affect scrolling speed at all. Also for some reason i don't have xinput speed and sensitivity params (to try What is the best way to configure a Thinkpad's TrackPoint? solutions).

enter image description here /sys/devices/platform/i8042/serio1$ xinput --list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ETPS/2 Elantech Touchpad id=12 [slave pointer (2)] ⎜ ↳ ETPS/2 Elantech TrackPoint id=13 [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)] ↳ Integrated IR Camera: Integrate id=9 [slave keyboard (3)] ↳ Integrated Camera: Integrated C id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=14 [slave keyboard (3)]

Try out:

xinput set-prop "ETPS/2 Elantech TrackPoint" "libinput Accel Speed" 2

and see if it increased the speed. You could put this setting on your ~/.xinitrc so that it'll be saved for your user.

  • Seems like 1 is max value. The range is from -1 to 1. Anyway it doesn't affect scrolling speed, only cursor speed.
