libinput-m...d-pressure(1)  General Commands Manual libinput-m...d-pressure(1)

NAME
       libinput-measure-touchpad-pressure - measure pressure properties	of de-
       vices

SYNOPSIS
       libinput	  measure   touchpad-pressure	[--help]  [options]  [/dev/in-
       put/event0]

DESCRIPTION
       The libinput measure touchpad-pressure tool measures  the  pressure  of
       touches	on a touchpad. This is an interactive tool. When executed, the
       tool will prompt	the user to interact with the  touchpad.  On  termina-
       tion,  the tool prints a	summary	of the pressure	values seen. This data
       should be attached to any pressure-related bug report.

       For a full description on  how  libinput's  pressure-to-click  behavior
       works,  see  the	 online	 documentation here: https://wayland.freedesk-
       top.org/libinput/doc/latest/touchpad_pressure.html   and	  https://way-
       land.freedesktop.org/libinput/doc/latest/palm_detection.html

       This  is	 a  debugging tool only, its output may	change at any time. Do
       not rely	on the output.

       This tool usually needs to be  run  as  root  to	 have  access  to  the
       /dev/input/eventX nodes.

OPTIONS
       If a device node	is given, this tool opens that device node. Otherwise,
       this  tool  searches  for the first node	that looks like	a touchpad and
       uses that node.

       --touch-thresholds="down:up"
	       Set the logical touch pressure thresholds to down and  up,  re-
	       spectively.  When  a  touch  exceeds the	pressure in down it is
	       considered logically down. If a touch  is  logically  down  and
	       goes  below  the	pressure in up,	it is considered logically up.
	       The thresholds have to be in  device-specific  pressure	values
	       and it is required that down >= up.

       --palm-threshold=N
	       Assume  a  palm threshold of N.	The threshold has to be	in de-
	       vice-specific pressure values.

       --thumb-threshold=N
	       Assume a	thumb threshold	of N.  The threshold has to be in  de-
	       vice-specific pressure values.

       If  the	touch-thresholds  or the palm-threshold	are not	provided, this
       tool uses the thresholds	provided by the	device quirks (if any) or  the
       built-in	defaults.
