Ho risolto in un altro topic il problema della wireless adesso rimane il problema della risoluzione dello schermo.
Sicuramente è un problema di driver Nvidia perchè dava più o meno lo stesso problema su Ubuntu 8.04.1 .
Ho fatto alcuni tentativi seguendo questi passaggi
http://www.debianitalia.org/modules/wfsection/article.php?articleid=141. (debian way) solo che al riavvio il server xorg crasha per via dei driver penso errati .
Adesso son ripartito da zero almeno a 800x600 lavoro!
