    is_enabled, timeout).

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   screensaver => *str*

        Explicitly set screensaver program to use.

        The default, when left undef, is to detect what screensaver is
        running,

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)

  prevent_screensaver_activated_until_interrupted
    Usage:

     prevent_screensaver_activated_until_interrupted() -> [status, msg, payload, meta]

    Prevent screensaver activated until interrupted.

    Uses Proc::Govern to run "sleep infinity", with the option
    `no-screensaver' to instruct Proc::Govern to regularly simulate user
    activity, thus preventing the screensaver from ever activating. To stop
    preventing screensaver from activating, press Ctrl-C.

    Available in CLI with two shorter aliases: pause-screensaver and noss.

    This function is not exported.

    No arguments.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
