Las dependencias necesarias con Conky + Lua + Cairo, dependiendo de la distro es su instalacion, solo busquen el paquete full de conky y ahi viene con lua y cairo.
El archivo .conkyrc se instala en /home/tu_usuario y se crea una carpeta oculta llamada .boxconky en su home, (/home/tu_usuario/.boxconky) en donde se guarda los archivos rings.lua y box.lua asi como el logo de su distro.
Aqui unas imagenes:

--[[BOX WIDGET v1.1 by Wlourf 27/01/2011
This widget can drawn some boxes, even circles in your conky window
http://u-scripts.blogspot.com/2011/01/box-widget.html)
Inspired by Background by londonali1010 (2009), thanks ;-)
The parameters (all optionals) are :
x - x coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
y - y coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
w - width of the box, default = width of the conky window
h - height of the box, default = height of the conky window
corners - corners is a table for the four corners in this order : top-left, top-right,bottom-right, bottom-left
each corner is defined in a table with a shape and a radius, available shapes are : "curve","circle","line"
example for the same shapes for all corners:
{ {"circle",10} }
example for first corner different from the three others
{ {"circle",10}, {"circle",5} }
example for top corners differents from bottom corners
{ {"circle",10}, {"circle",10}, {"line",0} }
default = { {"line",0} } i.e=no corner
operator - set the compositing operator (needs in the conkyrc : own_window_argb_visual yes)
see http://cairographics.org/operators/
available operators are :
"clear","source","over","in","out","atop","dest","dest_over","dest_in","dest_out","dest_atop","xor","add","saturate"
default = "over"
border - if border>0, the script draws only the border, like a frame, default=0
dash - if border>0 and dash>0, the border is draw with dashes, default=0
skew_x - skew box around x axis, default = 0
skew_y - skew box around y axis, default = 0
scale_x - rescale the x axis, default=1, useful for drawing elipses ...
scale_y - rescale the x axis, default=1
angle - angle of rotation of the box in degrees, default = 0
i.e. a horizontal graph
rot_x - x point of rotation's axis, default = 0,
relative to top-left corner of the box, (not the conky window)
rot_y - y point of rotation's axis, default = 0
relative to top-left corner of the box, (not the conky window)
draw_me - if set to false, box is not drawn (default = true or 1)
it can be used with a conky string, if the string returns 1, the box is drawn :
example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
linear_gradient - table with the coordinates of two points to define a linear gradient,
points are relative to top-left corner of the box, (not the conky window)
{x1,y1,x2,y2}
radial_gradient - table with the coordinates of two circle to define a radial gradient,
points are relative to top-left corner of the box, (not the conky window)
{x1,y1,r1,x2,y2,r2} (r=radius)
colour - table of colours, default = plain white
this table contains one or more tables with format {P,C,A}
P=position of gradient (0 = start of the gradient, 1= end of the gradient)
C=hexadecimal colour
A=alpha (opacity) of color (0=invisible,1=opacity 100%)
Examples :
for a plain color
for a gradient with two colours {x=80,y=150,w=20,h=20,
radial_gradient={20,20,0,20,20,20},
colour=,
or -with this one, gradient will start in the middle
for a gradient with three colours
and so on ...
To call this script in Conky, use (assuming you have saved this script to ~/scripts/):
lua_load ~/scripts/box.lua
lua_draw_hook_pre main_box
And leave one line blank or not after TEXT
Changelog:
+ v1.0 -- Original release (19.12.2010)
+ v1.1 -- Adding parameters: operator, dash, angle, skew_x, skew_y, draw_me
corners are described in a table

--[[Clock Rings by Linux Mint (2011) reEdited by despot77
This script draws percentage meters as rings, and also draws clock hands if you want! It is fully customisable; all options are described in the script. This script is based off a combination of my clock.lua script and my rings.lua script.
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 145 uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num>5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num>3; conversely if you update Conky every 0.5s, you should use update_num>10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
