I'm running Arch Linux. On a recent update of Xorg, evdev was replaced by libinput (by default). When this happened, I lost the xinput properties I use for making my TrackPoint behave properly. Specifically, the properties I rely upon are:

  • Device Accel Profile
  • Device Accel Constant Deceleration
  • Device Accel Adaptive Deceleration
  • Device Accel Velocity Scaling

I had to roll my system back to using evdev. Obviously, that's only a short term solution.

How can I set acceleration and deceleration for the TrackPoint in libinput going forward? xinput list-props doesn't list any properties that obviously (to me) replace those above.

Is anyone else using a TrackPoint with the latest xorg-server and libinput and also making use of custom acceleration and deceleration values?

I have large monitors, so I need the cursor to move fast when I have a long distance to travel, but I need it to have good control when selecting characters and doing other detail work.

These are the evdev-based properties that work well for me:

Device 'Synaptics Inc. Composite TouchPad / TrackPoint (Stick)':
    Device Enabled (152):   1
    Coordinate Transformation Matrix (154): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
    Device Accel Profile (276):     5
    Device Accel Constant Deceleration (277):       3.700000
    Device Accel Adaptive Deceleration (278):       4.700000
    Device Accel Velocity Scaling (279):    60.000000
    Device Product ID (271):        1739, 9
    Device Node (272):      "/dev/input/event7"
    Evdev Axis Inversion (280):     0, 0
    Evdev Axes Swap (282):  0
    Axis Labels (283):      "Rel X" (162), "Rel Y" (163)
    Button Labels (284):    "Button Left" (155), "Button Middle" (156), "Button Right" (157), "Button Wheel Up" (158), "Button Wheel Down" (159)
    Evdev Scrolling Distance (285): 0, 0, 0
    Evdev Middle Button Emulation (286):    0
    Evdev Middle Button Timeout (287):      50
    Evdev Third Button Emulation (288):     0
    Evdev Third Button Emulation Timeout (289):     1000
    Evdev Third Button Emulation Button (290):      3
    Evdev Third Button Emulation Threshold (291):   20
    Evdev Wheel Emulation (292):    1
    Evdev Wheel Emulation Axes (293):       0, 0, 4, 5
    Evdev Wheel Emulation Inertia (294):    10
    Evdev Wheel Emulation Timeout (295):    200
    Evdev Wheel Emulation Button (296):     2
    Evdev Drag Lock Buttons (297):  0

I also use xset m 5 to give me the final acceleration I need.

The question is, how to replicate these settings with libinput and newest xorg-server?
