Well, that didn’t happen, yet, and users who want to play the latest Linux games have to either compile the latest Mesa 3D libraries from sources or rely on either the well-known Oibaf or Padoka PPAs (Personal Package Archives), which include only development, but highly optimized versions of Mesa and related libraries. For those who don’t want to install those devel versions of Mesa on their Ubuntu boxes, there’s also the Padoka Stable Mesa PPA, which was recently updated to the latest stable Mesa 13.0.3 3D Graphics Library, and now a user asks Canonical to backport it to the Ubuntu 16.04 LTS HWE (Hardware Enablement) stack.
