Almost a year back, I had predicted and requested that Valve consider building an entire distro on top of Linux, and with it the ability to armtwist nVidia and ATI to build great driver support in Linux.

Update (Sep 24, 2013): Well, that day is here - Valve just announced SteamOS - a completely new distro built on top of Linux, however with a few improvements.

In SteamOS, we have achieved significant performance increases in graphics processing, and we’re now targeting audio performance and reductions in input latency at the operating system level.

This is going to be huge in the Linux world - the base OS that Valve builds will undoubtedly come with its standardized libraries, driver support and third party hardware support. That could potentially be used a foundation to build a desktop OS as well that could well disrupt the market.

Oh, and the first casualty is already here. Welcome nVidia - they have begun to work with the Nouveau open source graphics drivers.

NVIDIA is releasing public documentation on certain aspects of our GPUs, with the intent to address areas that impact the out-of-the-box usability of NVIDIA GPUs with Nouveau. We intend to provide more documentation over time, and guidance in additional areas as we are able.
