GeForceFX Dual-screen no work!

Sugarat · 09-01-04, 05:25 PM

Hi All,

Can somebody please point out to me what it is I'm missing here. I have three large Sun monitors connected to my system. Two of them (the middle one, and the left one) are fed from a GeForce FX. The right one is fed by a PCI Radeon card. With my current configuration none of them seem to be working, although the middle screen and the right one, driven off a radeon 'were' working before I fiddled with the config file.

I don't want to use TwinView, but instead want to have each head on the GeForce FX configured in x.org as a separate display. Having followed the NVIDIA Instructions.. I've got precisely nowhere.

Help!

Log file and config file follow.. Many thanks.

Here is the log..

Whenever you get the "Multiple displays connected, but only one display allowed" error that means you need to put "ConnectedMonitor" options in each Screen section. Put

Option "ConnectedMonitor" "CRT-0"

in your LeftScreen "Screen" section and

Option "ConnectedMonitor" "CRT-1"

in your Middle "Screen" section.

And it will work for some stupid reason.

Do those option strings need to be in the Screen section then, - I thought they needed to be under the device sections?

Thanks for your advice however, - gave it a try and still no joy. I've got the middle and right screen working, but the extra head of the GeForce still no wanna play.

The log now contains this:

(WW) NVIDIA: More than one matching Device section found: Videocard2

I am rapidly coming to the conclusion that X is a pile of sh**. How can I fix this problem now..?

Well in my case they worked in the Screen section.

You might want to try uncommenting the BusId lines. I'm sure you can isolate the problem by eliminating things.
