NVIDIA Optimus Unofficially Comes To Linux
NVIDIA's Optimus multi-GPU technology now works under Linux. Well, at least for some notebooks, it's been hacked together by an open-source developer and in fact is working to use both Intel and NVIDIA graphics processors simultaneously with the respective drivers. This is the best Linux implementation we've seen yet with NVIDIA Corp still not announcing plans to officially support this technology under non-Microsoft operating systems.
Back in early 2010 we learned that NVIDIA had no plans to bring this support to Linux that provides seamless switching for notebooks between Intel and NVIDIA graphics, depending upon workload and power requirements to provide the best overall experience while hopefully extending your laptop's battery life.
