[$] Linux ecosystem contributions from SteamOS

The SteamOS Linux
distribution is focused on gaming, naturally, but the effort to build it
has resulted
in contributions to multiple areas in the Linux ecosystem. Alberto Garcia
has been working on SteamOS and came to Bilbao, Spain to describe some of those
contributions at Open Source Summit Europe 2023. There are some obvious
areas where a gaming-focused OS might contribute upstream, such as
graphics, but the talk showed contributions in several other areas as well.
