Salut jean4111, 🙂
C'est un petit logiciel qui s'appelle
conky, faut d'abord installer le paquet conky-all. Ensuite tu crées un fichier .conkyrc que tu places dans ton home (pour le mien il y a en plus un script lua pour afficher les barres vertes). Tu trouveras plein d'exemples sur ce
topic.
Je te laisse le mien pour te donner une idée (en sachant qu'il faudra le modifier pour qu'il fonctionne sur ton ordi) :

Et le script bargraph_small.lua de wlourf à placer dans ~/.conky/scripts :
--[[ BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
this widget draws a bargraph with different effects
http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/bargraph.lua
lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
Parameters are :
3 parameters are mandatory
name - the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
arg - the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
arg can be a numerical value if name=""
max - the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
Optional parameters:
x,y - coordinates of the starting point of the bar, default = middle of the conky window
cap - end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
http://www.cairographics.org/samples/set_line_cap/
angle - angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
set to 90 for an horizontal bar
skew_x - skew bar around x axis, default = 0
skew_y - skew bar around y axis, default = 0
blocks - number of blocks to display for a bar (values >0) , default= 10
height - height of a block, default=10 pixels
width - width of a block, default=20 pixels
space - space between 2 blocks, default=2 pixels
angle_bar - this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
radius - for cicular bars, internal radius, default=0
with radius, parameter width has no more effect.
Colours below are defined into braces {colour in hexadecimal, alpha}
fg_colour - colour of a block ON, default= {0x00FF00,1}
bg_colour - colour of a block OFF, default = {0x00FF00,0.5}
alarm - threshold, values after this threshold will use alarm_colour colour , default=max
alarm_colour - colour of a block greater than alarm, default=fg_colour
smooth - (true or false), create a gradient from fg_colour to bg_colour, default=false
mid_colour - colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
3 colurs to gradient created by fg_colour and alarm_colour, default=no mid_colour
led_effect - add LED effects to each block, default=no led_effect
if smooth=true, led_effect is not used
possibles values : "r","a","e" for radial, parallelel, perdendicular to the bar (just try!)
led_effect has to be used with theses colours :
fg_led - middle colour of a block ON, default = fg_colour
bg_led - middle colour of a block OFF, default = bg_colour
alarm_led - middle colour of a block > ALARM, default = alarm_colour
reflection parameters, not avaimable for circular bars
reflection_alpha - add a reflection effect (values from 0 to 1) default = 0 = no reflection
other values = starting opacity
reflection_scale - scale of the reflection (default = 1 = height of text)
reflection_length - length of reflection, define where the opacity will be set to zero
calues from 0 to 1, default =1
reflection - position of reflection, relative to a vertical bar, default="b"
possibles values are : "b","t","l","r" for bottom, top, left, right
draw_me - if set to false, text is not drawn (default = true or 1)
it can be used with a conky string, if the string returns 1, the text is drawn :
example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
v1.0 (10 Feb. 2010) original release
v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value
v1.2 (28 Feb. 2010) just renamed the widget to bargraph
v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
