Bonsoir a tous,
suite a un probleme sur mon laptop Hp G6, j'ai du changer de carte mére. j'ai garder mon disque dur avec Fedora 17 installer dessus.
bizarement il boot bien sauf que l'ecran reste éteint. on vois bien les fenetres avec une lampe.
comment pourrais-je regler ce probleme?
Voici mon lsmod
