@Zander: one other thing: I'm using a GeForce 6200 AGP video card with my Solaris box. When I followed the guide for making a driver alias for my video card (to make the driver support my card), the alias appearenty already existed. Is it true that the drivers now come with driver aliases for regular GeForce video cards in addition to the officially supported Quadro cards? And if this is the case, could you add these cards to the Supported Products list? It would be very helpful to a lot of people.
@game-master: the 1.0-8175 X driver enables the UseEdidFreqs option by default, it's possible that your problem is related to this change. You can try disabling this option.
Thanks. That was the problem. I sat the UseEdidFreqs option to false, and the out of sync problem disappeared.
