comportement bizard: wifi déconnecté - plantage au démarrage ...
Bonjour,
J'ai un soucis très embêtant.
Lors de certains démarrages d'Ubuntu, j'obtiens un écran noir, le témoin de mon wifi est éteint mais par contre, le témoin du Shift Lock clignote sans arrêt.
Je suis alors obligé de couper le portable de façon barbare et de redémarrer. Ca peut se produire parfois jusqu'à cinq fois à la suite.
Quand enfin Ubuntu termine son démarrage, tout fonctionne correctement quelques semaines puis ça recommence et je ne sais pas d'où ça peut provenir.
Par curiosité, j'ai installé une autre distribution et je n'ai jamais eu de problèmes avec elle mais je préfère nettement Ubuntu et j'aimerais trouver la solution et ne pas à avoir attendre la version 9.04 d'Ubuntu pour résoudre ce problème assez embêtant.
J'espère que quelqu'un pourra m'aider et/ou me mettre sur la voie.

Bonjour,
J'ai connu un problème semblable. J'ai installé le paquet "linux-backports-modules-intrepid" et mon problème s'est réglé, je n'ai plus de freeze.
