I am running Ubuntu 12.04 64bit on MacBook Pro 15" 2010 (MacBookPro6,2) and I would like to use the integrated Intel graphics instead of the dedicated Nvidia graphics Ubuntu boots with on this machine.
I am booting with UEFI, not REFIT or similar. I managed to switch to UEFI with the help of this page.
This wiki page also contains tips on switching to Intel graphics which include some (for me) cryptic boot commands to grub. However if I follow the guide, my display stays just black.
Currently, I am only looking for solution to use Intel graphics for Ubuntu to save power and keep my MacBook cool. Dynamic switching or stuff like that is not required.
