Problems with Twinview and/or DFP Monitor

[Ivan]

I've been trying to use a CRT and a LCD monitors in a Twinview configuration, using a Geforce 4 Ti4200, but I can't.
There's always the same error message: "Screens found, but no usable configuration"
As a result, I can't see anything in the LCD monitor. But the worse thing of all is that I even can't use the LCD alone if I use the NVIDIA driver! If I configure it to use only the LCD, I get "No signal input" on the monitor screen.

I'm quite new to Linux, but I remember I could do this with RedHat8 and 41.91 drivers, but now I'm using Redhat9 and 43.49, and I just can't fix it.

I've used YANC to configure XF86, but it still doesn't work.

Can anyone help me find the way, please?

Yea, I'm having the same problem... I posted it in a new thread before seeing this, I've found that you can get TwinView to start if you specify the second monitor as a CRT, but that doesn't give you any visuals on the flatpanel display. Check out my post and compare what I said to your situation.:afro:

I've tried with some of the options form you XFconfig file, but no results at all...

If I choose CRT,CRT for ConnectedMonitors, my flatpanel shows "No signal input".

If I choose CRT,DFP, X doesn't start, giving me the same error as always: Unable to read mapping of screens in CRC's, and no usable configuration for the screens and so on...

Can anyone help me find a solution? If nobody knows how to set it up for Twinview, I could live using ONLY the LCD monitor, but I don't even know how to do it. It looks like the nvidia drivers are having some trouble with the LCD monitor.

You are getting exactly the same results as I am. I think it just doesn't like flat panel displays. Have you tried to connect another CRT as your second monitor? I think I will do that... I'll post my results upon completion.

Well, I tried hooking up two CRT's to my GeForce4 using a Digital to Analog converter for the DVI port... and I got some wierd results.

When I used my TwinView enabled version of XF86Config-4 and I ran startx, the Nvidia logo image showed up off center on my main CRT. It showed up off to the right regardless of what the option TwinViewOrientation said (LeftOf/RightOf).
The second CRT had no picture.

So then I switched back to my old non-TwinView XF86Config-4, with the second CRT still connected, and ran startx. The main monitor went black and my second monitor flickered on and there was the picture!

Here are both my XF86Config-4s:
