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. --help Print help --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.
