Hi, I'm new to Ubuntu and Linux in general but I'm doing ok so far, I have an Acer Aspire Revo R3600 with 2gb PC2-6400 RAM and an Intel Atom™ CPU 230 @ 1.60GHz × 2 processor. Everything is working but the system is generally a little slow and some websites (kids games) are glitchy and the videos freeze. At first I though I would install more RAM but now I'm wondering if the graphics driver is the problem? Its an NVIDIA ION video card as far as I can tell. I have the NVIDIA accellerated graphics proprietary driver installed (not the experimental one) and activated according to Additional Drivers, but when I go to System Settings > Details > Overview, it lists the Graphics as 'Unknown'. Is this ok or is something wrong?

I would appreciate any advice, I'm no techie so be gentle! Thanks in advance.
