El escritorio actual en mi laptop incorpora Fedora 15 + Tint2 + Conky.
En las últimas versiones de conky ya viene incorporado los archivos para cargar lua y cairo, así que basta solo con instalar la última version de conky de nuestra distro.
Este conky tiene tres archivos, el primero y principal se llama .conkyrc que va en nuestro home (/home/tu_usuario), en donde tu_usuario es como lo indica el nombre de tu usuario con el que te logueas.
Despues creamos una carpeta llamada .boxconky en nuestro home (/home/tu_usuario) dentro de esta carpeta van los archivos box.lua y rings.lua, tambien va el logo de nuestra distro que se debe llamar logo.png para no cambiar el script en .conkyrc, en caso de que no quieran cambiarle el nombre al logo entonces lo tendran que hacer en el script.
Bueno aqui el codigo:

--[[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 {{1,0xFFFFFF,0.5}}
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 {{1,0x00FF00,0.5}}
for a gradient with two colours {{0,0x00FF00,0.5},{1,0x000033,1}} {x=80,y=150,w=20,h=20,
radial_gradient={20,20,0,20,20,20},
colour={{0.5,0xFFFFFF,1},{1,0x000000,0}},
or {{0.5,0x00FF00,1},{1,0x000033,1}} -with this one, gradient will start in the middle
for a gradient with three colours {{0,0x00FF00,0.5},{0.5,0x000033,1},{1,0x440033,1}}
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:

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):

Creo que no esta demas aclarar que ninguno de los codigos es de mi autoria, dentro de rings.lua y box.lua viene la referencia a sus autores, yo solo los modifique a mi gusto personal.
