libinput-debug-events - debug helper for libinput


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


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.


--device /dev/input/event0
Use the given device with the path backend
Exclusively grab all opened devices. This will prevent events from being delivered to the host system.
Print help
Only print libinput messages, don't print anything from this tool. This is useful in combination with --verbose for internal state debugging.
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".
Use verbose output
