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.
