Question Dual Head under Linux

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.

Default Twinview setup guide needed

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...

Default Thanks for the info

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
