I have been trying, with no success so far, to get Dual Head to work under Linux.
I would like to run Two monitors attached to an Nvidia Ti4200 one on Analogue VGA the other on DVI with adaptor to VGA.
Either Xinerama or just two seperate X-Servers would suit me.

I have tried the usual settings in XF86config, but I kep getting and error:
'(WW) NVIDIA(0): Multiple monitors detected, but only one display allowed!'
Is this a built-in limitation by the Nvidia driver?
I am using the nvidia driver version 1.0.4349.

My system is Suse Linux 8.0 with kernel 2.4.18

I would also like to get TV-out, but that is not of great importance.

Any suggestions, or am I floggin' a dead horse (English translation: trying the impossible)?

(XF86config and X-Server log attached)

Do you actually have two Ti4200's, one PCI and one AGP? Because that's the way your BusID's are set up...

I think you want TwinView, and only one Device section. Not two Devices, two Monitors, and all that goes along with that. Check out "Configuring TwinView" in the README.

As a side effect, you can then get 3D acceleration across both monitors.

You could also check out Appendix R in the README for how to get multiple X screens on one card with different CRTC's, if you don't want to use TwinView.

It is quite right that I have a setup looking for two PCI id's. I did this following some advice from a website on dual monitor setup.
I forst tried enabling the TwinView option but only got 1 display.
OK. So you have answered my basic question, and that is that it *is* possible to have two monitors on the one nvidia card.
*And* if I hear correctly, possible to have two X-servers on the one card (with dual outlets). The latter being the mode of most interest to me.

One more question, where is 'The README' located?
I am no slouch with Google search, but have yet to 'strike gold' with a refernce to a list of Options and such in relation to the secretive Nvidia driver for Linux.

Is that all I need?, just one URL, and all the mysteries will be explained.....

I pray it is so.... ;)

I can only assume you mean this README, although you should have struck it when you downloaded the drivers...

ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4349/README.txt

Thanks,
Yes it was right under my nose, all the info I was looking for.

I got my drivers from Suse, as the Nvidia supplied ones don't work on Suse Linux.

Thanks for the tip :)
