NAME
       libinput-debug-events - debug helper for libinput

SYNOPSIS
       libinput debug-events [options]

       libinput debug-events [options] --udev <seat>

       libinput debug-events [options] [--device] /dev/input/event0
       [/dev/input/event1...]

DESCRIPTION
       The libinput debug-events tool creates a libinput context and prints
       all events from these devices.

       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
       --device /dev/input/event0
               Use the given device(s) with the path backend. The --device
               argument may be omitted.

       --grab  Exclusively grab all opened devices. This will prevent events
               from being delivered to the host system.

       --help  Print help

       --quiet Only print libinput messages, don't print anything from this
               tool. This is useful in combination with --verbose for internal
               state debugging.

       --show-keycodes
               Key events shown by this tool are partially obfuscated to avoid
               passwords and other sensitive information showing up in the
               output. Use the --show-keycodes argument to make all keycodes
               visible.

       --udev <seat>
               Use the udev backend to listen for device notifications on the
               given seat.  The default behavior is equivalent to --udev
               "seat0".

       --verbose
               Use verbose output

   libinput configuration options
       --apply-to="pattern"
               Configuration options are only applied where the device name
               matches the pattern. This pattern has no effect on the
               --disable-sendevents option.

       --disable-sendevents="pattern"
               Set the send-events option to disabled for the devices matching
               patterns.  This option is not affected by the --apply-
               to="pattern" option.

       --set-click-method=[none|clickfinger|buttonareas]
               Set the desired click method

       --set-scroll-method=[none|twofinger|edge|button]
               Set the desired scroll method

       --set-scroll-button=BTN_MIDDLE
               Set the button to the given button code

       --set-profile=[adaptive|flat|custom]
               Set pointer acceleration profile

       --set-speed=<value>
               Set pointer acceleration speed. The allowed range is [-1, 1].
               This only applies to the flat or adaptive profile.

       --set-custom-points="<value>;...;<value>"
               Sets the n points defining a custom acceleration function The
               points are defined in a semicolon-separated list of floating
               point non-negative numbers. Defaults to "0.0;1.0".  This only
               applies to the custom profile.

       --set-custom-step=<value>
               Sets the distance along the x-axis between each point, starting
               from 0.  Defaults to 1.0.  This only applies to the custom
               profile.

       --set-custom-type=[fallback|motion|scroll]
               Sets the type of the custom acceleration function.  Defaults to
               fallback.  This only applies to the custom profile.

       --set-tap-map=[lrm|lmr]
               Set button mapping for tapping

NOTES
       Events shown by this tool may not correspond to the events seen by a
       different user of libinput. This tool initializes a separate context.
