lien entre wifi et UbuntuStudio ?!
Bonjour à tous,
Je suis sous KDE. Un peu d'historique pour situer la venue de mon problème :
J'ai installé certains paquets UbunbuStudio (je précise : pas le métapaquet desktop), croyant que ces paquets là ne faisaient que regrouper un ensemble de logiciels (J'étais avant sur la distrib complète UbunbuStudio).
Bien mal m'en a pris. Je me suis retrouvé au prochain démarrage sous une session de Gnome !
Bref redémarrage, et je précise que je veux une session KDE.
Désinstallation des paquets UbunbuStudio précédemment installés (autoremove --purge).
Toujours gnome de proposé dans le menu login, mais bon ça à la limite c'est pas grave.
Là où le bas blesse c'est que depuis ça, mon wifi ne marche pas...
J'ai la fameuse Broadcom 4318, mais auparavant, une simple installation de b43-fwcutter puis une dist-upgrade avait mis mon wifi en service. Maintenant que-nenni, ça ne marche plus. Je ne vois aucun réseau, mon gestionnaire de wifi me dis gentiment "wlan interface disconnected".
Lors de l'installation de KDE j'avais fait des recherches pour avoir mon wifi en marche, et fwcutter était la seule méthode qui marchait dans mon cas. Mais là même avec cette méthode ça ne marche plus, donc je ne sais plus trop quoi faire 
Merci d'avance !
Edit : je précise que la led du wifi est bien allumée.
