Hello

I have a Macbook Pro 6.2, 10.2 and 10.1.
All run under Ubuntu 13.04. (Kernel 3.8.0-22-generic)
I haven't found any means to activate the integrated Intel Graphics
card. By default, the NVidia is recognized and activated.

As all of my machines are production machines, I have limited resources
to support experiments but are willing to help out.

Unfortunately my French is not up to the standards to read the webpage
you suggested in your mail.
