Comment 9 for bug 435906

If it would be possible to switch between graphics cards then consequently it would also be possible to turn off the one you don't need. It seems like there is a lot of effort being made for the master bug, I don't think another project will start just for this one as this is just a subset of the main project.
What makes you think this is just a one-liner? There are many different laptops with many different graphics cards.
