Linux godfather Linus Torvalds may have a frosty relationship with NVIDIA, but that hasn't stopped the company from improving its hardware's support for the open-source operating system. In fact, the chipset-maker is working on the OS' compatibility with its Optimus graphics switching tech, which would enable laptops to conserve power by swapping between discrete and integrated graphics on the fly. In an email sent to a developer listserv, NVIDIA software engineer Aaron Plattner revealed that he's created a working proof of concept with a driver. There's no word on when the Tux-loving masses may see Optimus support, but we imagine that day can't come soon enough for those who want better battery life while gaming on their mobile machines.
