I just installed Mathematica on my laptop. I use Linux Mint 17. My problem is that I cannot see any 3D graphics. Or more precisely, when I open the Plot3D reference page, I can see the 3D graphs, but when I run the codes myself, the graphs disappear. On the other hand, in the advanced Manipulate functionality tutorial I don't even see the original 3D graphs, just a blank screen of the correct size. 2D graphics work fine. As I understand, I probably have to do something with the video drivers, but if you could direct me to some detailed directions, it would be helpful. Thanks, Ferenc
