NAME

SYNOPSIS

9       libinput debug-events [options]
10
11       libinput debug-events [options] --udev <seat>
12
13       libinput debug-events [options] [--device] /dev/input/event0

DESCRIPTION

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

OPTIONS

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