SYNOPSIS

10
11       libinput debug-events [options] --udev <seat>

14       put/event1...]

DESCRIPTION

17       The libinput debug-events tool creates a libinput  context  and  prints
18       all events from these devices.
19
20       This  is  a  debugging tool only, its output may change at any time. Do
21       not rely on the output.
22
23       This tool usually needs to be  run  as  root  to  have  access  to  the
24       /dev/input/eventX nodes.
25

OPTIONS

27       --device /dev/input/event0
28               Use the given device(s) with the path backend. The --device ar‐
29               gument may be omitted.
30
31       --grab  Exclusively grab all opened devices. This will  prevent  events
32               from being delivered to the host system.
33
34       --help  Print help
35
36       --quiet Only  print  libinput  messages, don't print anything from this
37               tool. This is useful in combination with --verbose for internal
38               state debugging.
39
40       --show-keycodes
41               Key events shown by this tool are partially obfuscated to avoid
42               passwords and other sensitive information  showing  up  in  the
43               output.  Use  the --show-keycodes argument to make all keycodes
44               visible.
45
46       --udev <seat>
47               Use the udev backend to listen for device notifications on  the
48               given  seat.   The  default  behavior  is  equivalent to --udev
49               "seat0".
50
51       --verbose
52               Use verbose output
53
54   libinput configuration options
55       --apply-to="pattern"
56               Configuration options are only applied where  the  device  name
57               matches  the  pattern. This pattern has no effect on the --dis‐
58               able-sendevents option.
59
60       --disable-sendevents="pattern"
61               Set the send-events option to disabled for the devices matching
62               patterns.   This option is not affected by the --apply-to="pat‐
63               tern" option.
