Mir Display Server May Not Arrive on Desktops As Default Until 2016
|
|||
|
|
================================================================================
|
|||
|
|
**Ubuntu’s next generation display server Mir, developed by Canonical as a flexible alternative to Wayland and XServer, could be facing another delay on its way to the desktop. **
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
The technology was initially positioned as a candidate for shipping by default on the desktop later this year but, [in a video address][1] to developers, Mark Shuttleworth has now intimated that Mir may not find its way on to the Ubuntu desktop until the release of Ubuntu 16.04 LTS — in 2016.
|
|||
|
|
|
|||
|
|
Responding to a question asking when users could expect to find it available on PCs, Shuttleworth replied:
|
|||
|
|
|
|||
|
|
> “I expect Mir to be the display server [to be default] as soon as it’s rock solid and we have a story we’re really proud of on it. You can run it on your desktop [now], but we don’t want to let a love of technology interfere with our mission to be great for the user. This is a great place for us to set the bar very high in terms of performance…where we have freedom to get it right, without having to worry too much about compatibility.
|
|||

> By 16.04 it’ll be the default display server…That’s the kind of timeline we’re looking at.”

### Mir Oh Mir ###
|
|||
|
|
|
|||
|
|
It’s not immediately clear what impact, if any, such a delay would mean for Unity 8, scheduled to arrive on desktops this October.
|
|||
|
|
|
|||
|
|
Similarly, it’s also not clear from his words whether the ‘by 16.04′ references a pure Mir experience or something akin to the Mir + Xmir hybrid proposed for Ubuntu 13.10. Either way a slip in timeframe is a hazard of any development process. Display servers are not easy technologies to build, particularly when designing one to span all manner of screen sizes and form factors.
|
|||
|
|
|
|||
|
|
This delay, if as assured as some news outlets are reporting it as being, won’t be the first to scupper Canonical’s plans. Ubuntu [originally intended to land a Mir Hybrid in Ubuntu 13.10][2], but technical flaws prevented that from happened. Its inclusion in the upcoming release of 14.04 LTS [was also ruled][3] out early on.
|
|||
|
|
|

|
### Mir As It Is ###
|
|||
|
|
|
|||
|
|
As disappointing as the above may read Mir is continuing to evolve at breakneck pace. In fact, while it won’t be default, it will be possible to install a Mir session in Ubuntu 14.04 LTS, bundled with an in-progress version of the Unity 8 desktop. It’s also rocking out as the default on Ubuntu Touch for both phones and tablets.
|
|||
|
|
|
|||
|
|
But on the desktop it looks like things may take a little longer. Unlike on phones and tablets, where Ubuntu is able to make use of Android device drivers [via Hybris][4], there are currently no proprietary AMD, Intel or Nvidia desktop graphics drivers supporting Mir. Upstream support in open-source drivers remain patchy at best, with Canonical [being forced][5] to carry patches to enable functionality.
|
|||
|
|
|
|||
|
|
**The more time Canonical has to refine, iterate and improve on the technology in its desktop form, the better the end user experience of it will be.**
