How can I change the TrackPoint sensitivity and speed settings of Thinkpad TrackPoint Keybroad II on Ubuntu 20.04? The
On Ubuntu 16.04, it is easy to set with xinput set-prop "pointer:Lenovo TrackPoint Keyboard II" "Device Accel Constant Deceleration" 0.3. However, on Ubuntu 20.04, the property "Device Accel Constant Deceleration" doesn't exist. I have set the "libinput Accel Speed" 1, but the trackpoint is still too slow and hard to use. For configuring the etc/xorg.conf.d, I can't login to the desktop. Could you please give me some suggestions to set the speed of trackpoint faster?
Here is the properties:
