libinput debug-events [options] --udev <seat>

libinput debug-events [options] [--device] /dev/input/event0 [/dev/input/event1...]

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.

8 --device /dev/input/event0 Use the given device(s) with the path backend. The --device argument may be omitted.

8 --grab Exclusively grab all opened devices. This will prevent events from being delivered to the host system.

8 --help Print help

8 --quiet Only print libinput messages, don't print anything from this tool. This is useful in combination with --verbose for internal state debugging.

8 --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.

8 --udev <seat> Use the udev backend to listen for device notifications on the given seat. The default behavior is equivalent to --udev "seat0".

8 --verbose Use verbose output

8 --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.

8 --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.
