Do you want to use you card with CUDA? Your card isn’t a CUDA enabled device.

I found the answer in the Ubuntu Foruns

Ubuntu Forums

It basicly disables your onboard vidio (in this case intel) by blacklisting it (make linux ignore it). I did the same on my windows xp side by disabling the onboard video card using the the device manager.

I hope this helps

I follow the steps and it works.
