NAME

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

SYNOPSIS

       evemu-describe [/dev/input/eventX] [output file]

       evemu-record [--autorestart=s] [/dev/input/eventX] [output file]

DESCRIPTION

       evemu-describe gathers information about the input device and prints it to stdout. This information can
       be parsed by evemu-device(1) to create a virtual input device with the same properties.

       evemu-record captures events from the input device and prints them to stdout. The events can be parsed by
       evemu-play(1) to let a virtual input device created with evemu-device(1) emit the exact same event
       sequence.

       evemu-describe and evemu-record need to be able to read from the device; in most cases this means they
       must be run as root.

       If an event node is provided, evemu-describe and evemu-record use that event node. Otherwise, the user
       must interactively choose from a list of detected devices.

       If no output file is given, stdout is used.

OPTIONS

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

DIAGNOSTICS

       If evtest-record does not see any events even though the device is being used, the device may be grabbed
       by a process (EVIOCGRAB). This is usually the case when debugging a synaptics or wacom device from within
       X. VT switching to a TTY or shutting down the X server terminates this grab and the devices can be
       recorded. For most X drivers, disabling the device also removes the grab.

       The following command shows the processes with an open file descriptor on the device.

           fuser -v /dev/input/eventX
