Voilà comment faire un petit conky qui épatera tes amis avec ses formes en cercle 
Installation
Pour cette recette, il nous faut conky et acpi
$ sudo apt-get install conky-all acpi
Les fichiers
Personnellement, je suis du style à oublier de récupérer le fichier caché .conkyrc
avant de réinstaller une distribution! Du coup je vous propose tout simplement de se faire un fichier “Conky” dans le répertoire “Documents”. Et de lancer
le conky depuis celui-ci!
$ mkdir ~/Documents/Conky
Nous allons remplir le fichier conkyrc:
$ nano ~/Documents/Conky/conkyrc
Mettez cette configuration:
# Conky settings #

Maintenant, nous allons créer le script LUA qui gère les cercles:
$ nano ~/Documents/Conky/cercles.lua
et ajouter le script:

Vous pouvez tester tout ceci avec la commande:
$ conky -c ~/Documents/Conky/conkyrc
Lancer conky au démarrage
Il vous faut trouver l'applicatif qui gère les applications au démarrage.
Pour unity, vous trouverez l'information ici :
http://doc.ubuntu-fr.org/tutoriel/application_demarrage.
Pour XFCE (debian/ubuntu/Fedora), allez dans Menu > Settings Manager > Session & Startup.
Dans l'onglet "Application Autostart", faites "Add", puis remplicez ainsi:
name : conky
commande : sh -c "sleep 5 && (conky -c /home/linuxmoi/Documents/conky/conky-ring/conkyrc &)"
Enregistrer! Vous n'avez plus qu'à relancer votre distribution pour tester le démarrage.
J'ai rajouté un sleep de 5 secondes pour que le démarrage de conky se réalise bien.
