Sustituí los plasmoides monitores del sistema por conky, ya que tengo un memory leak en los plasmoides. Estos son mas visuales, pero conky abulta mucho menos:

Dejo el conky.conf:
conky.config = {
    alignment = 'bottom_left',
    gap_x = 0,
    gap_y = 0,
    background = false,
    border_width = 1,
    cpu_avg_samples = 2,
    default_color = '#d1be8f',
    default_outline_color = 'white',
    default_shade_color = 'white',
    draw_borders = false,
    draw_graph_borders = true,
    draw_outline = false,
    draw_shades = false,
    use_xft = true,
    font = 'FreeMono:size=15:bold',
    minimum_height = 5,
    minimum_width = 1920,
    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 = 'normal',
    own_window_hints = 'undecorated,sticky,skip_taskbar,skip_pager',
    stippled_borders = 0,
    update_interval = 1.0,
    uppercase = false,
    use_spacer = 'none',
    show_graph_scale = false,
    show_graph_range = false,
    double_buffer = true
}
