C’est amusant Linux
il est vrai que je n’utilise pas gnome intégralement, je n’aime pas leurs applis music ( j’utilise vlc) , logiciels ( je préfère toujours Synaptic) , Nautilus ( je préfère Thunar) etc, que je trouve bien trop lourde spour mon petit pc
En fait j’utilise essentiellement gnome-shell
