Using the latest ubuntu 13.10 and trying to get the propriatory (spelling) drivers for my GeForce 8500 GT. But it doesnt show in the "additional settings". Its blank. Am I doing something wrong or should I download it from the Nvidia homepage? How do I install it? Step by step would be awsome for me as a non-geek
The nvidia-319 drivers are the ones you want.
See: http://www.nvidia.com/object/linux-display-amd64-319.32-driver.html (from the package description, visible in Synaptic)
