Confirmed via `udevadm test /sys/class/input/eventX` that POINTINGSTICK_* properties were not being set for my T430s trackpoint. After adding a local entry file (as advised in this file), the same `udevadm test` command showed properties. More importantly, the movement of mouse using trackpoint felt much better. Hard to describe its previous state, but following come to mind: slippery, hard to control, awkward. Now it feels more consistent and predictable. A little on the sensitive side with the defaults, but didn't think it warranted dedicated properties just for this series though as the X230 is same generation and uses the defaults. Before local change: $ udevadm info /dev/input/event5 P: /devices/platform/i8042/serio1/serio2/input/input6/event5 N: input/event5 E: DEVNAME=/dev/input/event5 E: DEVPATH=/devices/platform/i8042/serio1/serio2/input/input6/event5 E: ID_BUS=i8042 E: ID_INPUT=1 E: ID_INPUT_MOUSE=1 E: ID_INPUT_POINTINGSTICK=1 E: LIBINPUT_DEVICE_GROUP=11/2/a:synaptics-pt/serio0 E: MAJOR=13 E: MINOR=69 E: SUBSYSTEM=input E: USEC_INITIALIZED=38609915 After change: $ udevadm info /dev/input/event5 P: /devices/platform/i8042/serio1/serio2/input/input6/event5 N: input/event5 E: DEVNAME=/dev/input/event5 E: DEVPATH=/devices/platform/i8042/serio1/serio2/input/input6/event5 E: ID_BUS=i8042 E: ID_INPUT=1 E: ID_INPUT_MOUSE=1 E: ID_INPUT_POINTINGSTICK=1 E: LIBINPUT_DEVICE_GROUP=11/2/a:synaptics-pt/serio0 E: MAJOR=13 E: MINOR=69 E: POINTINGSTICK_CONST_ACCEL=1.0 E: POINTINGSTICK_SENSITIVITY=200 E: SUBSYSTEM=input E: USEC_INITIALIZED=38609915

# Pointingstick const-accel configuration, to make different brand / model
|
||
# laptop pointingsticks have the same speed / feel, and per model adjustment
|
||
# of the IBM TrackPoint driver's sensitivity setting
|
||
#
|
||
# The lookup keys are composed in:
|
||
# 60-evdev.rules
|
||
#
|
||
# Note: The format of the "evdev:" prefix match key is a contract between the
|
||
# rules file and the hardware data, it might change in later revisions to
|
||
# support more or better matches, it is not necessarily a stable ABI.
|
||
#
|
||
# Supported hardware matches are:
|
||
# - Generic input devices match:
|
||
# evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV
|
||
# This matches on the kernel modalias of the input-device, mainly:
|
||
# ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and
|
||
# WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV
|
||
# is an arbitrary length input-modalias describing the device capabilities.
|
||
# The vendor, product and version ID for a device node "eventX" is listed
|
||
# in /sys/class/input/eventX/device/id.
|
||
#
|
||
# - Input driver device name and DMI data match:
|
||
# evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn*
|
||
# <input device name> is the name device specified by the driver,
|
||
# <vendor> is the firmware-provided string from the kernel DMI modalias,
|
||
# see /sys/class/dmi/id/modalias
|
||
#
|
||
# To add local entries, create a new file
|
||
# /etc/udev/hwdb.d/71-pointingstick-local.hwdb
|
||
# and add your rules there. To load the new rules execute (as root):
|
||
# systemd-hwdb update
|
||
# udevadm trigger /dev/input/eventXX
|
||
# where /dev/input/eventXX is the pointingstick in question. If in
|
||
# doubt, simply use /dev/input/event* to reload all input rules.
|
||
#
|
||
# If your changes are generally applicable, preferably send them as a pull
|
||
# request to
|
||
# https://github.com/systemd/systemd
|
||
# or create a bug report on https://github.com/systemd/systemd/issues and
|
||
# include your new rules, a description of the device, and the output of
|
||
# udevadm info /dev/input/eventXX.
|
||
#
|
||
# Allowed properties are:
|
||
# POINTINGSTICK_CONST_ACCEL
|
||
# POINTINGSTICK_SENSITIVITY
|

#
|

# Entries should be sorted with growing _SENSITIVITY and _CONST_ACCEL.
