I just upgraded my main system from fc5 to fc6. I have an nvidia BFG something or other, with one vga and one dvi port. I was connected to two monitors, one big CRT via VGA and one small LCD via VGA. One of the VGAs via an adapter to the DVI port.
So I clearly have an fc6 system, an nvidia card, and an LCD with only a VGA interface. Thus my reply.
I'm actually in flux, and am giving away the CRT. I had been in fc5 with the nvidia drivers and using RandR for multihead, which I got to work after some pains. Now, I am just using the LCD-VGA, and haven't yet installed the nvidia driver (using nv). I did notice, that my CRT which is still connected displays text garbage. And I think I did have to manually add a monitor section to my xorg.conf.
Anyway, if there is a specific question or experiment you would like me to try, let me know.
could you try to connect your LCD using the VGA port without the adapter? This is what I am not being able to accomplish. It is like the modelines were wrong.
Thank you for the reply.
