Como activar los iconos del menu de Sistema en Ubuntu
5 jul
Algo que no me gusta de la nueva versión de Ubuntu, es que en el menú de Sistema, no aparecen los iconos a la izquierda de cada opción. Podemos ver en el gráfico como se muestra originalmente este menú (seguramente en tu Ubuntu también se verá así).
Si abrimos un terminal (Aplicaciones -> Accesorios -> Terminal) y tecleamos:
<pre>gconftool-2 –type Boolean –set /desktop/gnome/interface/menus_have_icons True</pre>
Activaremos los iconos del menú de Sistema, cuyo aspecto es mas agradable que sin ellos y lo veremos así.
Como veréis el cambio es para mejor. En caso de que no os agrade o penséis que la carga del sistema aumenta y queréis desactivarlo de nuevo, solo tenéis que teclear en un Terminal (Aplicaciones -> Accesorios -> Terminal) lo siguiente:
<pre>gconftool-2 –type Boolean –set /desktop/gnome/interface/menus_have_icons False</pre>
