I have got an Asus N53 laptop with Core i7 2630QM CPU and nVidia GT 550M GPU. On Windows, i watch movies and play games. Which i need GPU. But on Ubuntu, i just develop web sites only use Netbeans and Chrome. But ubuntu uses GPU as default which means more heating, more noise, more power consumption etc.

How can i disable nVidia on ubuntu and use only intel onboard graphics?

The nVidia GT 550M GPU is soldered to the motherboard in the Asus N53, so this is the onboard graphics. The Intel graphics you are talking about is the GPU inside the CPU. – Dennis Dec 19 '11 at 11:06

You need to install an application to automate using the Nvidia Optimus technology, which allows you to switch between the integrated and discrete GPU. As far as I'm aware, Nvidia provides support for this feature only in their Windows drivers.

Some of these applications include The Ironhide Project or The Bumblebee Project.

If you're up for a bit of a read, this website covers many of the aspects related to disabling the card, and being able to use it when active.
