To turnoff nvidia graphics card and use it only when required install The Bumblebee:
If you are on 11.04 or older , you will need new drivers, run
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
Add the Stable Bumblebee Releases PPA and install Bumblebee using the proprietary NVIDIA driver:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia
If you have 32-bit applications like Wine, and run 11.10 Oneiric or later, you will need extra libraries:
sudo apt-get install virtualgl-libs:i386
Allow yourself to use Bumblebee by adding yourself to the 'bumblebee' group. (replace $USER by your username)
sudo usermod -a -G bumblebee $USER
Reboot or re-login to apply the group changes
If you'd like to run a program on the nvidia card now, use the optirun program:
optirun firefox &
