Aalto Talk with Linus Torvalds 
TLDR:  Linus at a Q&A, a woman asks why Nvidia still isn't providing any support for Optimus on Linux, Linus responds that Nvidia is being really difficult about that without good reason and "Fuck You Nvidia!" (flicks off the camera).Her question actually starts a minute earlier than the link:http://www.youtube.com/watch?v=MShbP3OpASA&t=48m14sPS - Bravo Linus.  This is issue is a real PITA, and a bit incongruent considering the historically awesome driver support Nvidia has provided for Linux.
