Usar varios Conky’s al mismo tiempo

Conky es una interesante herramienta que nos sirve para monitorizar nuestro sistema (entre otras cosas) y aunque hace mucho, mucho tiempo no lo uso (pues ha perdido el sentido, por lo menos para mi), me encantaba por ser una aplicación sencilla, que consume pocos recursos.

Normalmente cuando ejecutamos y configuramos Conky, solo usamos una sola instancia pero ¿Qué tal si queremos usar varias? Como se puede ver en la siguiente imagen, por ejemplo:

Veamos como hacerlo. Para ello tenemos que crear varios archivos, 3 en este caso:

1. .conkyrc_mail para la notificación de correos
2. .conkyrc_sistema para información del sistema
3. .conkyrc_time para el reloj en el escritorio

Creamos una carpeta llamada .conky en nuestro /home.

$ mkdir ~/.conky

Luego abrimos un terminal como y como root creamos un archivo en /usr/local/bin con el nombre start_conky:

$ sudo touch /usr/local/bin/start_conky

y le ponemos adentro lo siguiente:

#!/bin/bash
conky -c /home/tu_usuario/.conky/.conkyrc_sistema &
conky -c /home/tu_usuario/.conky/.conkyrc_hora &
conky -c /home/tu_usuario/.conky/.conkyrc_mail &

Ya lo que nos queda es darle permisos:

$ sudo chmod a+x /usr/local/bin/start_conky
$ sudo chown root:staff /usr/local/bin/start_conky

Pero puede pasar que Conky arranque antes de que el Escritorio termine de cargar y desaparezca. Para solucionar esto creamos un archivo en la ruta /home/tu_usuario/.config/autostart bajo el nombre conky_start (es un nombre diferente al fichero creado en /usr/local/bin) y le ponemos adentro:

#!/bin/bash
sleep 15
start_conky
exit 0

Podemos cambiar el valor sleep 15 en dependencia del tiempo que demore en cargar nuestro escritorio.

Hasta aquí la parte relevante de este artículo. Si quieren copiar los script que se usan para el ejemplo anterior, sigan leyendo.
