Bug Description

Binary package hint: compiz

Most motherboards now come with integrated graphics chips and people add in their discrete graphics cards.

OSX has enabled a new feature (recently introduced with its new Core i5 laptops), that allow the system to switch between integrated and discrete graphics _on the fly_.

Note that this is not something that is supported by specific hardware, but instead is something that the operating system does : http://arstechnica.com/apple/news/2010/04/inside-apples-automatic-gpu-switching.ars

Such a feature allows for significantly increased battery time and since is done totally in software, would be a great addition to Linux.

affects: compiz (Ubuntu) → xorg (Ubuntu)
