NAME

6       evemu-describe, evemu-record - print information and events from an
7       input device
8

SYNOPSIS

10       evemu-describe [/dev/input/eventX] [output file]
11
12       evemu-record [--autorestart=s] [/dev/input/eventX] [output file]
13

DESCRIPTION

15       evemu-describe gathers information about the input device and prints it
16       to stdout. This information can be parsed by evemu-device(1) to create
17       a virtual input device with the same properties.
18
19       evemu-record captures events from the input device and prints them to
20       stdout. The events can be parsed by evemu-play(1) to let a virtual
21       input device created with evemu-device(1) emit the exact same event
22       sequence.
23
24       evemu-describe and evemu-record need to be able to read from the
25       device; in most cases this means they must be run as root.
26
27       If an event node is provided, evemu-describe and evemu-record use that
28       event node. Otherwise, the user must interactively choose from a list
29       of detected devices.
30
31       If no output file is given, stdout is used.
32

OPTIONS

34           --autorestart=<s>
35                 Terminate the current recording after <s> seconds of device
36                 inactivity. This option requires an output, the file is suffixed
37                 with the date and time of the recording's start.
38                 The timeout must be greater than 0.
39

DIAGNOSTICS

41       If evtest-record does not see any events even though the device is
42       being used, the device may be grabbed by a process (EVIOCGRAB). This is
43       usually the case when debugging a synaptics or wacom device from within
44       X. VT switching to a TTY or shutting down the X server terminates this
45       grab and the devices can be recorded. For most X drivers, disabling the
46       device also removes the grab.
47
48       The following command shows the processes with an open file descriptor
49       on the device.
