TwinView and DVI + RGB problem

[mikeoneil]

I have an Nvidia G4 ti4200 which has 1 DVI and 1 RGB output. The driver is the last but one, ie. 4349. I used to have my LCD screen connected to the DVI and all was fine.

Now I want to add a second LCD to the RGB port and use TwinView.

After many hours editing XConfig-4 I can only conclude that TwinView only allows two RGB connections and not 1 DVI / 1RGB.

I can only get a twinview working if I add "ConnectedMonitor" "CRT, CRT" to the config file. If I try "DFP" X crashes on startup. Other times I've had only the 'second' monitor working. How does X know which port of the graphic card is the main monitor and which is the second?

 

Can I use the DVI connection on the main monitor whilst using TwinView?

check out this file:

/usr/share/doc/NVIDIA_GLX-1.0/README

 

it has a lot of info on twnview and just using the nvidia drivers and setting up your XF86Config in general. I don't know the exact answer to your problem, but posting your current /etc/XF86Config-4 may be helpful :)

I have this file in printed form and have been all the way through it. It was a great help (along with Dolsons tutorial, thanks!) in getting as far as I have. I have a fully working twinview setup with two RGB screens. My main screen, on its own, worked using the DVI input. So far, I have been unable to get it to work on DVI with twinview enabled. The second screen is RGB only and a different resolution.

 

Here is the relevant part of my XConfig-4 file

Without the line "ConnectedMonitor", X crashes as it does with anything except CRT, CRT. The error was something about screen not usable.

Hopefully someone can help!?
