Ok, this is not related to Slackware directly, but i still wanted to post it here anyways. David Airlie has posted a video (unfortunately not the best video) about a demonstration how GPU Switching can be done in Linux. While this might not be a problem in Windows 7, this operation is not yet supported on any Linux distribution.
Nevertheless, it doesn't stop people to try to create a script that enables users to switch between GPU (mostly are Intel GMA and NVidia or ATI) so that it would have longer battery life, since if we don't turn off one of them, it will drain the battery faster.
I'm looking forward to see this script available to any Linux distribution, so i can start using my NVidia GPU instead of using Intel GMA on my ASUS UL80VT laptop.
