.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.B "libinput debug\-events"
|
|
tool creates a libinput context and prints all events from these devices.
|
|
.PP
|
|
This is a debugging tool only, its output may change at any time. Do not
|
|
rely on the output.
|
|
.PP
|
|
This tool usually needs to be run as root to have access to the
|
|
/dev/input/eventX nodes.
|
|
.SH OPTIONS
|
|
.TP 8
|
|
.B \-\-device \fI/dev/input/event0\fR
|
|
Use the given device(s) with the path backend. The \fB\-\-device\fR argument may be
|
|
omitted.
|
|
.TP 8
|
|
.B \-\-grab
|
|
Exclusively grab all opened devices. This will prevent events from being
|
|
delivered to the host system.
|
|
.TP 8
|
|
.B \-\-help
|
|
Print help
|
|
.TP 8
|
|
.B \-\-quiet
|
|
Only print libinput messages, don't print anything from this tool. This is
|
|
useful in combination with --verbose for internal state debugging.
|
|
.TP 8
|
|
.B \-\-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
|
|
.B \-\-show\-keycodes
|
|
argument to make all keycodes visible.
|
|
.TP 8
|
|
.B \-\-udev \fI<seat>\fR
|
|
Use the udev backend to listen for device notifications on the given seat.
|
|
The default behavior is equivalent to \-\-udev "seat0".
|
|
.TP 8
|
|
.B \-\-verbose
|
|
Use verbose output
|
|

|
|
.B \-\-disable-sendevents="pattern"
