Installing the latest nVidia drivers (180.29) on Ubuntu Intrepid is quite easy. First, pull up a terminal (for gnome, Applications > Accessories > Terminal) and enter the following command.


sudo gedit /etc/apt/sources.list


You will be prompted for your password. At the bottom of the newly opened file insert the following lines:


deb http://ppa.launchpad.net/anders-kaseorg/ppa/ubuntu intrepid main
deb-src http://ppa.launchpad.net/anders-kaseorg/ppa/ubuntu intrepid main


Save and close the file. Now go back to the terminal and enter the following command to authenticate the PPA repository we've specified in our repository list.


sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 026491A5DD081BDC6CDFC0DE6298AD34413576CB


Now we are ready to install. In the terminal once again we'll enter the following.


sudo apt-get update
sudo apt-get install nvidia-glx-180


The terminal will prompt you to make sure it is okay to install the package and remove the old ones. You may confirm this with a "y" for yes.

After the packages have been installed you may restart your computer. When you log back in your new drivers will be active.

I noticed a huge increase in performance on several applications including Gnome-Do's Docky app.
