I recently installed Ubuntu and I am fairly new to it. I have a GeForce GTX 550 ti and I want to install my graphic drivers on it.

So I disable stop lightdm sudo service lightdm stop. I then go to where my driver is. and type ./NVIDIA-Linux-x86_61-331.20.run

It then gives me the error:

ERROR: The Noveau kernel driver is currently in use by your system. This driver is incompatible with the NVIDIA driver, and must be disabled before proceeding

I really have no idea how to approach this.

If you install the Nvidia drivers via the additional drivers GUI in Ubuntu it will disable the open-source drivers and install the Nvidia drivers automatically. It will also be much easier to disable/upgrade them later. In 12.04 open the dash and type "additional drivers" in 13.04> type "software update" in 12.04 it will scan and then give you a lost of drivers on startup. In 13.04+ the additional drivers is the last tab to the right, when you click on it, it should scan and give you the drivers. The sacn can take a minute so give it time, you also must be connected to the internet... –  TrailRider Dec 28 '13 at 18:31
