Nvidia 550 ti + Dual Monitor not Working

[Races1986]

Hello,

I bought a new Nvidia card and since then I've had several problems with my Ubuntu integration. First, I had some problems because it was freezing after booting. I gave up and stopped using Ubuntu for a while. One day, my computer restarted directly to ubuntu and it was magically working (GREAT). Now, I am trying to use my two Acer monitors. As of now, one monitor is working fine and the second one (which is located to left) is totally white and the mouse pointer shows a black "X" instead of the common white arrow (I am including this ifnroamtion because I noticed other people have had similar problems), I can move my pointer to the "white" monitor, but I cannot move different windows to the second monitor (there is a sort of boundary that stop the window from moving to the second monitor). I dont know if this is a known issue but any help would be most appreciated.

Attached is my xorg.conf file
Thanks

PS: I tried to include a Shutter capture of my whole desktop but it only takes the one that is working fine.

Thanks again...


UPDATE
I have made it work.
I ran

sudo nvidia-settings

and click on "Enable Xinerama"
Both Monitors are working now, but in Unity 2d.

Wow.... I really love Unity 3d.. does anyone know how to bring it back?

Thanks
