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.
