NAME

libinput-debug-events - debug helper for libinput

libinput debug-events [options]

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.

–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

–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

Events shown by this tool may not correspond to the events seen by a different user of libinput. This tool initializes a separate context.
