NAME

       libinput-debug-events - debug helper for libinput

SYNOPSIS

       libinput     debug-events     [--help]     [--show-keycodes]    [--udev    <seat>|--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 <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
