3 # Pointingstick const-accel configuration, to make different brand / model
4 # laptop pointingsticks have the same speed / feel, and per model adjustment
5 # of the IBM TrackPoint driver's sensitivity setting
7 # The lookup keys are composed in:
10 # Note: The format of the "evdev:" prefix match key is a contract between the
11 # rules file and the hardware data, it might change in later revisions to
12 # support more or better matches, it is not necessarily a stable ABI.
14 # Supported hardware matches are:
15 # - Generic input devices match:
16 # evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV
17 # This matches on the kernel modalias of the input-device, mainly:
18 # ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and
19 # WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV
20 # is an arbitrary length input-modalias describing the device capabilities.
22 # - Input driver device name and DMI data match:
23 # evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn*
24 # <input device name> is the name device specified by the driver,
25 # <vendor> is the firmware-provided string from the kernel DMI modalias.
27 # To add local entries, create a new file
28 # /etc/udev/hwdb.d/71-pointingstick-local.hwdb
29 # and add your rules there. To load the new rules execute (as root):
30 # udevadm hwdb --update
31 # udevadm trigger /dev/input/eventXX
32 # where /dev/input/eventXX is the pointingstick in question. If in
33 # doubt, simply use /dev/input/event* to reload all input rules.
35 # If your changes are generally applicable, open a bug report on
36 # http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
37 # and include your new rules, a description of the device, and the
39 # udevadm info /dev/input/eventXX
40 # (or /dev/input/event*).
42 # Allowed properties are:
43 # POINTINGSTICK_CONST_ACCEL
44 # POINTINGSTICK_SENSITIVITY
46 # Entries should be sorted with growing _SENSITIVITY and _CONST_ACCEL.
