Ciao a tutti,
E da quasi due anni che sul mio portatile hp ( core i3 370m - 4gb ram - hd5470 che non c'è verso di farla andare al posto della hd3000 intel) che utilizzo linux mint 13.
Di solito al boot va tutto liscio, ma saltuariamente dopo aver scelto mint da grub rimane lo schermo nero e non va più avanti. Ho anche tolto il quiet splash dalle direttive del boot, ma sempre schermo nero resta.

Nel log trovo questo:

Qualcuno sa come risolvere?
