# This file is part of systemd.
#
# 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.
#
# - 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.
#
# 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):
# udevadm 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, open a bug report on
# http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
# and include your new rules, a description of the device, and the
# output of
# udevadm info /dev/input/eventXX
# (or /dev/input/event*).
#
# Allowed properties are:
# POINTINGSTICK_CONST_ACCEL
# POINTINGSTICK_SENSITIVITY
#
#########################################
# POINTINGSTICK_CONST_ACCEL #
#########################################
#
# Trackpoint const accel settings are specified as
# POINTINGSTICK_CONST_ACCEL=<accel>
#
# Where <accel> is a floating point number, using a '.' seperator, specifying
# by how much to multiply deltas generated by the pointingstick to get
# normalized deltas.
#
#########################################
# POINTINGSTICK_SENSITIVITY #
#########################################
#
# TPPS/2 IBM TrackPoint driver sensitivity sysfs setting
# POINTINGSTICK_SENSITIVITY=<sensitivity>
#
# Where <sensitivity> is a number between 0 and 255, note this property
# only applies to TPPS/2 IBM TrackPoint devices, see
# drivers/input/mouse/trackpoint.c in the Linux kernel sources.
#
#
# Sort by by brand, model

# Lenovo Thinkpad X200s / X201s
# Note these come with 2 revisions of keyboard, with the trackpoints having a
# different sensitivity in the different revisions. 1.25 is a bit slow for the
# least sensitive revision, but it is better to be a bit slow than too fast.
