For those current users of Ubuntu 12.04 LTS curious about how the performance of Ubuntu 14.04 LTS will be if upgrading, I've been in the process of running some preview benchmarks to share the current situation of the Trusty Tahr in its present development form. Some early results to share this weekend run a few OpenGL benchmarks while comparing the state of Ubuntu 12.04.3 to Ubuntu 14.04 right now when using Intel "Ivy Bridge" HD Graphics 4000.

As an extra holiday present for Linux and open-source fans, Intel has quietly released a large batch of new programming documentation that covers their latest-generation Haswell graphics cores. The new "programmer's reference manuals" cover the 2013 Haswell HD Graphics, Iris Graphics, and Iris Pro Graphics. This massive batch of documentation is spread across twelve volumes and does document their hardware registers.
