NAME

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

SYNOPSIS

       evemu-describe [/dev/input/eventX]

       evemu-record [/dev/input/eventX]

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.

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
