libinput-measure-touchpad-pressure(1)        DragonFly General Commands Manual

NAME
       libinput-measure-touchpad-pressure - measure pressure properties of
       devices

SYNOPSIS
       libinput measure touchpad-pressure [--help] [options]
       [/dev/input/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
       termination, 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.freedesktop.org/libinput/doc/latest/touchpad_pressure.html
       and
       https://wayland.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,
               respectively. 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
               device-specific pressure values.

       --thumb-threshold=N
               Assume a thumb threshold of N.  The threshold has to be in
               device-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.
