I have a GeForce 6150SE nForce 430 graphics card installed in an HP Compaq Presario CQ5000 Series desktop with an AMD Athlon II X3 435 processor, 2GB RAM and Ubuntu 12.04 64-bit installed. I tried to install the NVIDIA driver from the Additional Drivers window for the recommended driver Nvidia 304 (Nvidia web recommends version 325, but says it is better to use the recommended Ubuntu driver!), but it failed!, and I need a driver to use Unity (3D). Thanks in advance for your help.
