To run your own copy of the NVidia drivers and not the ones that come in 
linux-restricted-modules you need to uninstall the 
linux-restricted-modules and a few other packages.

Start X with the nv driver and open Synaptic and search for everything 
that has the word nvidia in the name or description. Uninstall the 
linux-restricted-modules, the nvidia-glx driver, the 
nvidia-kernel-source and nvidia-kernel-common.

Restart the computer so that it drops any kernel modules and redo your 
NVIDIA-Linux-x86-169.12-pkg1.run installation. It will protest saying 
that it is already installed but continue anyway. It should prompt you 
to changes the settings in X so let it do this and restart your computer.

This process should remove all trace of the NVidia drivers that come 
with Ubuntu. The Ubuntu drivers are way out of date and you will get 
better picture etc with the ones from NVidia.

The NVidia driver will have installed a program called nvidia-settings 
you can run this to fine tune your X if needed but be warned to can make 
X look horrible.

"Mostly, it's serious fun for free software geeks, and
anyone else who believes that Linus' Law, "given enough eyeballs, all
bugs are shallow", is the path to better software" said Donna Benjamin,
Director of the linux.conf.au 2008 conference.
