Re: TwinView Problem With Two CRTs
If you're using two CRTs, then the ConnectedMonitor should reference two CRTs, not one CRT and one DFP.
Also, if both CRTs are identical (as they appear to be based on your bug report), then you shouldn't need to use these options in your X configuration:
(**) NVIDIA(0): Option "SecondMonitorHorizSync" "10-200"
(**) NVIDIA(0): Option "SecondMonitorVertRefresh" "50-160"
