Veniamo al dunque, questo pc ha due schede video, l'NVIDIA GT320 con uscita HDMI e quella integrata con uscita VGA che attualmente utilizzo con il mio monitor LCD. Dopo aver effettuato l'installazione del sistema ed installato i driver CUDA per la mia NVIDIA GT320, ovviamente collegata tramite HDMI, Snow Leopard riconosce la risoluzione del monitor ma il sistema diventa lentissimo, praticamente inusabile. Collegando il monitor LCD tramite VGA, ottengo una risoluzione massima di 1024x768 ed il sistema lavora benissimo. Come devo fare per aumentare la risoluzione del monitor? Il sistema riconosce la scheda video interna come una vga generica. Esistono kext specifici per la scheda video interna del mio acer x3900, il chipset è un Intel H57 con scheda video integrata. Sto impazzendo, aiutoooo!!!!
