Next Ubuntu release to have Mir as default Featured

The next release of Ubuntu, version 13.10, will have the new display server Mir as the default, according to Olli Ries, the engineering director for Ubuntu and Mir.

The Ubuntu GNU/Linux distribution is produced by Canonical, a company founded and led by Mark Shuttleworth, an entrepreneur and former Debian developer.

Mir was announced back in March by Ries, because, according to him, "none of the existing solutions would allow us to implement our vision without taking major compromises which would come at the cost of user experience and quality."

Most of the Linux world is looking to move from the venerable X.org display server to Wayland which is in development. For a while it looked as though Canonical would also go with the pack - until the announcement in March.

Ries said in an announcement on June 27 that Mir had evolved from a proof-of-concept, when announced, to a high-quality, high-performance component "that we think will deliver the fastest, cleanest display experience for the Ubuntu platform. We are confident that all desktop environments and derivatives will work well throughout the transition, based on our ability to provide a full X compatibility layer."

The migration path Ries laid out for the transition to Mir is given below:

Ubuntu 13.10: XMir on Mir by default, with a fallback session to X where there is no Mir driver support, supported for nine months.

Ubuntu 14.04 LTS: XMir as default with the fallback session removed, full Mir driver support, traditional LTS support for five years

Ubuntu 14.10 and beyond: Mir stack as default, including rootless X support for legacy X applications, supported for nine months.

(XMir: X & Unity7 running on top of the system compositor Mir. Mir stack: Mir as system compositor with Unity 8 as session shell on top.)

Along with the announcement, Canonical has also released a video of various desktop environments running on XMir on Mir on Ubuntu.

FREE WHITEPAPER - RISKS OF MOVING DATABASES TO VMWARE

VMware changed the rules about the server resources required to keep a database responding

It's now more difficult for DBAs to see interaction between the database and server resources

This whitepaper highlights the key differences between performance management between physical and virtual servers, and maps out the five most common trouble spots when moving production databases to VMware

1. Innacurate metrics
2. Dynamic resource allocation
3. No control over Host Resources
4. Limited DBA visibility
5. Mutual ignorance
