Re: FC8 with Nvidia driver 100.14.19 stuck in 640x480 resolution
In your bug report, I see:
(WW) NVIDIA(GPU-0): Unable to read EDID for display device DFP-0
(WW) NVIDIA(GPU-0): Unable to read EDID for display device DFP-1
If the EDID of both your display devices isn't getting detected, then the driver is falling back to safe defaults (640x480 in your case). Are your display devices directly attached to the graphics card, or is there some intermediary device (KVM, etc) inbetween?
Were you using the same 100.14.19 driver in FC6 ?
