I like sensitivity 125 and speed 80 on the T560; 190 and 90, inertia 10, on the T500.
I found this solution (X1 parameters) that automates everything and survives reboot :-)
Another update, March 2020Lalufu at github said,
You can also use
xinputto modify the libinput values directly:
xinputto show the pointers the system knows about. If you have a ThinkPad you should see something along the lines of
TPPS/2 IBM TrackPointor similar.
xinput --set-prop "TPPS/2 IBM TrackPoint" "libinput Accel Speed" -0.5
will modify the pointer speed. Play around with the value to see what you like. If you want this to survive a reboot you can stick this in .bash_profile.
