NAME
       libinput-debug-events - debug helper for libinput

SYNOPSIS
       libinput     debug-events     [help]     [show-keycodes]    [udev
       |device /dev/input/event0] [configuration options]

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 with the path backend

       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 
               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
