Moin,

mag sein, dass das jetzt eine dumme Frage ist oder ich zu blöd bin: Ich habe mir diesen Conky auf den Desktop geholt und einen Kalender integriert. Dazu musste ich die einzelnen Ringe der Uhr verschieben. Und bis auf einen, nämlich den mittleren, klappt das auch. Aber ich finde beim besten Willen nicht die entsprechende Zeile im Skript, um eben diesen Ring auch noch zu konfigurieren. Kann mir da jemand helfen?

Skript:

settings_table = {
    {
        -- Edit this table to customise your rings.
        -- You can create more rings simply by adding more elements to settings_table.
        -- "name" is the type of stat to display; you can choose from 'cpu', 'memperc', 'fs_used_perc', 'battery_used_perc'.
        name='time',
        -- "arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument. If you would not use an argument in the Conky variable, use ''.
        arg='%I.%M',
        -- "max" is the maximum value of the ring. If the Conky variable outputs a percentage, use 100.
        max=12,
        -- "bg_colour" is the colour of the base ring.
        bg_colour=0xffffff,
        -- "bg_alpha" is the alpha value of the base ring.
        bg_alpha=0.1,
        -- "fg_colour" is the colour of the indicator part of the ring.
        fg_colour=0xFF6600,
        -- "fg_alpha" is the alpha value of the indicator part of the ring.
        fg_alpha=0.2,
        -- "x" and "y" are the x and y coordinates of the centre of the ring, relative to the top left corner of the Conky window.
        x=100, y=150,
        -- "radius" is the radius of the ring.
        radius=50,
        -- "thickness" is the thickness of the ring, centred around the radius.
        thickness=5,
        -- "start_angle" is the starting angle of the ring, in degrees, clockwise from top. Value can be either positive or negative.
        start_angle=0,
        -- "end_angle" is the ending angle of the ring, in degrees, clockwise from top. Value can be either positive or negative, but must be larger than start_angle.
        end_angle=360
    },
