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.

       --enable-tap|--disable-tap
               Enable or disable tap-to-click

       --enable-drag|--disable-drag
               Enable or disable tap-and-drag

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

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

       --set-speed=<value>
               Set pointer acceleration speed. The allowed range is [-1, 1].
