    background = true,
    border_width = 1,
    cpu_avg_samples = 2,
    default_color = 'white',
    font = 'Bitstream Vera Sans Mono:size=10',
    gap_x = 10,
    gap_y = 10,
    minimum_height = 5,
    minimum_width = 5,
    net_avg_samples = 2,
    no_buffers = true,
    out_to_console = false,
    out_to_stderr = false,
    extra_newline = false,
    own_window = true,
    own_window_class = 'Conky',
    own_window_type = 'override',
    own_window_transparent = true,
    stippled_borders = 0,
    update_interval = 1.0,
    uppercase = false,
    use_spacer = 'none',
    show_graph_scale = false,
    show_graph_range = false
}
