Okay I have Ubuntu installed but am having one hell of a time trying to get it to recognize my Nvidia GeForce GT 525M graphis card. But my laptop also has intel 3000 graphics.

I am re-installing ubuntu and want to start fresh. I just want to use the intel 3000 for graphics, How can I do this? Does this happen automatically even if there is a dedicated graphics card?

If it does happen automatically, could anybody explain why my computer reverts to Unity 2d? I have another laptop with intel 3000 for graphics and it can handle unity just fine. Please Help!
