We hate to give you guys bad news, but Canonical’s engineers are still working hard these days to port all the goodies from the Ubuntu 16.10 (Yakkety Yak) repositories to Ubuntu 16.04 LTS, which is a long-term supported version, until 2019. These include the Linux 4.8 kernel packages and an updated graphics stack based on a newer X.Org Server version and Mesa 3D Graphics Library. Unfortunately for Linux gamers using either Ubuntu 16.04 LTS, Ubuntu 16.04.1 LTS, or Ubuntu 16.10, the graphics stack provided by default is outdated. While Ubuntu 16.10 is shipping with the Mesa 12.0.3 3D Graphics Library, Ubuntu 16.04 LTS is still using the ancient and unsupported Mesa 11.2.0 release. However, both are using the X.Org Server 1.18.4 display server.
