I have installed Ubuntu 12.04 64bit and update it. When i run application "Details", it says that, quote, "Graphics: Unknown". I tried to install manually newest nvidia drivers (310.40), driver was installed successful, but Ubuntu still cant see my videocard. My videocard is GeForce 660TI. I cant run steam because of this trouble. Please, help me!
