Quick TwinView question

[D. Michaud]

I'm trying to use TwinView (one CRT, one DFP) with a NVidia Quadro4-700 board.

I have these relevant settings in the Device section of my XF86Config-4 file:

Option "TwinView"
Option "SecondMonitorHorizSync" "30-80"
Option "SecondMonitorVertRefresh" "50-100"
Option "MetaModes" "1280x1024,1280x1024"
Option "TwinViewOrientation" "RightOf"
Option "ConnectedMonitor" "CRT,DFP"


I know that the refresh rates and modes are good. I can successfully use either display device by itself.

However, when using the above twinview configuration I always get the following error in the XFree86.0.log file:

(EE) NVIDIA(0): Failed to read mapping of display devices to CRTCs
(EE) Screen(s) found, but none have a usable configuration.

Does anyone know what might be happening? Perhaps twinview doesn't work with the Quadro4-700? (Although the specs say it supports something called "nView")

Any help would be appreciated.

Thanks,
D. Michaud

I wouldn't think so, but does putting a space after the comma in the ConnectedMonitor option help?

Yeah, nView == TwinView...

I tried using a space there, but it didn't help.

Interestingly, if I use only

Option "ConnectedMonitor" "CRT"

or

Option "ConnectedMonitor" "DFP"

with twinview enabled X appears to start up but the display is black and the monitor is not getting a sync.

with twinview disabled either monitor will work perfectly fine with the above ConnectedMonitor options.

As I said before, with twinview enabled with either

Option "ConnectedMonitor" "CRT, DFP"

or leaving out the ConnectedMonitor option I get that weird X error I described in the earlier message.

I'm using the 3123 drivers
