Salve ragazzi, quando rivvio il pc dopo l'installazione ottengo un errore simile a questo. L'underscore lampeggia ed gentoo non si muove, come potrei risolvere?[/code]

Hai risolto?

Io ho avuto un problema analogo ieri, passando al driver nouveau da nvidia. Alla fine ho seguito le istruzioni trovate sul wiki ufficiale http://nouveau.freedesktop.org/wiki/KernelModeSetting e ora mi funziona tutto.

Per la cronaca, con la mia scheda obsoleta, ho il file /etc/modprobe.d/nouveau.conf che contiene i seguenti valori:
Code:
options nouveau modeset=1 noaccel=1


Il noaccel mi è servito perché altrimenti si inchiodava il driver quando X sfruttava l'accelerazione grafica. :(
Ad ogni modo, per diagnosticare meglio il tuo problema (sempre che tu non abbia già risolto) occorre guardare anche /var/log/Xorg.0.log

controlla la conf del kernel ti sarai perso (ed i log di compilazione, se è il caso non compare come errore ed alle volte neppure come warn) qualcosa di utile tra le dipendenze (backlight/display suppoort & C).

Non uso nvidia quindi oltre non vado.
