NVIDIA Geforce 310M is not recognized for additional drivers

view story

http://ubuntuforums.org – My laptop (Samsung QX 410) has an NVIDIA 310M mobile GPU and an Intel Ironlake Mobile integrated GPU. Ubuntu only recognizes the Intel GPU when I type Code: lspci| grep VGA into the console. The additional Drivers tab is completely empty as well. I'm running the 64 bit version of 13.04 (Hardware)
