Ciao a tutti!
Mi sono appena iscritto al Forum... ed ho installato Linux Ubuntu 7.10, l'ultima versione uscita.
Ho un monitor LG L1960TQ e una scheda video Matrox G550. Uso con Windows normalmente il cavo DVI che era in dotazione con il monitor, la qualità è migliore rispetto al VGA.
Con Linux, però, subito dopo il boot del sistema operativo, il monitor segnala "Digitale: fuori campo 29,5 - 31 Hz".
Sembra che la scheda video gli invii un segnale con le frequenze sbagliate. Ma come è possibile?
Ovviamente con il cavo analogico non ci sono problemi, ma non posso ogni volta fare a cambio, desidererei che il cavo digitale funzionasse.
Esiste un driver per Linux per il mio monitor? Non l'ho trovato nell'elenco nell'interfaccia di configurazione, ho inserito "LG L1730P(Digital)", il più simile che ho visto.
Dicevano che questa versione di Ubuntu sarebbe stata più flessibile e semplice da configurare, ma come posso usarla senza monitor?
Accodo il file xorg.conf.
Ringrazio fin da ora chiunque potrà aiutarmi!
