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.

−−set−scroll−method=[none|twofinger|edge|button]
Set the desired scroll method
−−set−scroll−button=BTN_MIDDLE
Set the button to the given button code
−−set−profile=[adaptive|flat|custom]
Set pointer acceleration profile
−−set−speed=<value>
Set pointer acceleration speed. The allowed range is [-1, 1]. This only applies to the flat or adaptive profile.
−−set−custom−points="<value>;...;<value>"
Sets the n points defining a custom acceleration function The points are defined in a semicolon-separated list of floating point non-negative numbers. Defaults to "0.0;1.0". This only applies to the custom profile.
−−set−custom−step=<value>
Sets the distance along the x-axis between each point, starting from 0. Defaults to 1.0. This only applies to the custom profile.
−−set−custom−type=[fallback|motion|scroll]
Sets the type of the custom acceleration function. Defaults to fallback. This only applies to the custom profile.
−−set−tap−map=[lrm|lmr]
Set button mapping for tapping
−−set−rotation−angle=<degrees>
Set the rotation angle in degrees (0 to 360).
Events shown by this tool may not correspond to the events seen by a different user of libinput. This tool initializes a separate context.
