Pas de wifi après installation de ubuntu
Salut,
Je n'ai pas de wifi après avoir installer ubuntu. Par contre, l'ADSL fonctionne.
Que faire ?
Merci.
Antoine.

Ecran entièrement noir
Bonjour,
J'ai récemment installé UBUNTU, mais je ne sais pas s'il est bien installé.
En voulant changer la résolution de l'écran, j'ai coché la mauvaise case et depuis, le bureau est tout noir !
Que faire ?
Antoine.
Configuration : portable MSI S 271 sous Vista.
