Dual screens configuration

Hi.
My computer has two nvidia graphic cards. One of them is pci-express (no hdmi out) - the other one is the one integrated in the motherboard (hdmi out)

My idea, is having the main 21'' screen connected to the PCI-express vga port, and extending the desktop via the HDMI port of the internal screen to a 32'' screen.....
I have been trying with nvidia-settings and i got it to see gnome's login screen, but then, the system gets frozen when i log in...
Does anyone have the same configuration?
Im getting mad about this since i can configure it perfectly from windows, but linux still resistes

Anothe option would be using the nouveau driver instead of nvidia's open sorce one (discontinued, btw) should i start by here?

Thanks!!!

Re: Dual screens configuration

OK, sorry, i was on a rush before.

I decided to stop using the open source nvidia drivers, because of the reason said before.... i think it would be an step back, and soon or late, i would have to make the step, so, i think the best moment is now.
Back to bussiness.
i followed arch's wiki for installing nouveau (http://wiki.archlinux.org/index.php/Nouveau), and i uninstalled both nvidia and nvidia-utils packages.
Then, i started arch in runlevel 3, and ran "Xorg --configure"
Im using now the resulting xorg.conf file (which i attach below" and i make it to log in to gnome....... the driver looks pretty much stable for general purposes, as far as i saw.....

Here is my current /etc/X11/xorg.conf - i did not touch anything still

Until now, the 21'' screen plugged into the Nvidia 8600GT pci express card works perfectly.
Now comes the second part:
The 32'' screen connected via HDMI to the Nvidia 8300 embeeded in my motherboard still displays nothing.

First thing i tryed to do is go to gnome's "System -> Preferences - Screen" - This only shows the 21'' screen, and even if i click on the "detect screens" button, i dont see the other 32'' screen anywhere...

I would appreciate any help you could provide.
Ask me ANY more info that you would need to have a look on this subject, please.

Thanks!!

Re: Dual screens configuration

Are you sure your 'BusID's are correct in the Device section?  Maybe try to configure them one at a time so your sure those values are correct.

Re: Dual screens configuration

Finally i switched to the privative driver (downloaded from their page and so)... its note the best option, but it does what no other one did - easyly, i mean.

Thanks anyway!
