Hi... I'm definitely a newbie when it comes to Linux in general. I've had Ubuntu for about 2 months now, and on the whole. I've enjoyed my experience. However. I seem to have problems rendering 3D graphics. When I attempt to run anything with 3D graphics. I get something like this.. (Which is better than before... it used to just be an "invisible window") http://yfrog.com/0yscreenshotwprp
Does anyone have any idea what might be wrong, and how I could fix it? I'm not sure how to get the specs of my computer, as I got it for christmas a few years back, and have no idea what model it is or what cards are in it, etc.
