Laptop with vga external dual-monitors configuration issue

I am trying to span the display across 2 external 17" monitors connected via VGA y-splitter to my laptop. Currently it will only output the same thing to all 3 monitors (laptop-lcd, external-lcd#1, external-lcd#2).

Is there a way to treat both external LCDs as a single LCD and change the resolution on it to span across both LCDs?
Do I need an external 2nd video card to make this work?

Additional Information:
I am using the standard free nouveau driver included in the install, not the propritary Nvidia driver. The video card is a NVIDIA Quadro NVS 140M.

I have gone through posts for similar issues but was unable to find information for this specific issue.

Thank you in advance for your help!

For some reason I didn't think to search the nVidia website, Thanks very much for guiding me in the right direction!

Unfortunatly I just recovered my system from a failed nVidia driver install(going on direction from another forum) and I will try again after backing-up & I'll report back with hopefully successful results.

Thanks again GlennsPref!
