Hello Linux Geeksters. As you may already know, Canonical has been working a lot at Mir, their own display server, which is intended to be an alternative to the good old X.org server. Initially the Ubuntu developers planed to use Mir as default on Ubuntu 13.10 Saucy Salamander, but the idea was postponed due to some performance reasons.
Now, Canonical has announced at the Ubuntu Developer Summit (UDS) that Mir and XMir will not be implemented by default on Ubuntu 14.04 Trusty Tahr, because the next Ubuntu version will be still using Unity 7, which does not support the new system compositor.
For those who don’t know, Mark Shuttleworth’s big dream is to reach a full convergence between the desktop and mobile versions of Ubuntu.
The Ubuntu developers will not abandon the development of Mir, since it will be still running on the next versions of Ubuntu Touch. After the latest update, Mir got official support for the most important Android GPU vendors: AMR Tali T-604 GPU used on Nexus 10, Qualcomm Adreno 320 used on Nexus 4, Nvidia Tegra 3 used on Nexus 7 and PowerVR graphics used on Samsung Galaxy, via the libhybris open-source library.
Despite the fact that Ubuntu Touch is not stable enough to compete with Android and iOS, Canonical is in talks with many companies for shipping Ubuntu Touch based devices.
