# This file is part of systemd. # # The lookup keys are composed in: # 70-touchpad.rules # # Note: The format of the "touchpad:" 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 expected to be a stable ABI. # # Match string format: # touchpad:pnpid:: # # To add local entries, create a new file # /etc/udev/hwdb.d/71-touchpad-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 touchpad 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: # TOUCHPAD_HAS_TRACKPOINT_BUTTONS=1 # # If the TOUCHPAD_HAS_TRACKPOINT_BUTTONS property is set, this # device has # the trackpoint buttons wired up to the touchpad as # BTN_0, BTN_1 and BTN_2. This affects the Lenovo X1 Carbon 3rd # and the *50 series (T450, T550, etc.) # Lenovo X1 Carbon 3rd touchpad:pnpid:*LEN0048*: # Lenovo W541 touchpad:pnpid:*LEN004a*: # Lenovo T450s touchpad:pnpid:*LEN200f*: TOUCHPAD_HAS_TRACKPOINT_BUTTONS=1
