I am having some graphics card trouble.

I am fairly new to Ubuntu (and Linux in general) and am primarily a windows user.

I have an Asus K52Jc series laptop with an Nvidia Geforce 310m graphics card.

I need to install a later or better driver for the graphics card as I am having quite the plethora of issues running minecraft. Error reports suggest that I do not have "glx" (I'm not sure what exactly this is) and I do not know what drivers I currently have.

If any wayward enthusiast or someone with experience with this graphics card or one like it could provide some information regarding how to find what drivers I have, and how to fix them for my graphics card, I would be much appreciative.

Thank you.

64bit Ubuntu 12.04
