I have a GeForce FX/5-series card and I cannot install the driver using the Additional Drivers (jokey) tool.
I just installed Ubuntu 12.04 and installed all nvidia drivers, but my drivers are not activated, when I open Nvidia settings manager I get the following message:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run
nvidia-xconfigas root), and restart the X server.
Can you help me with this?
