It's been a while since last having any major Mir Display Server news to talk about. The central Mir Bazaar repository for Ubuntu 14.04 LTS developments has been silent lately, but finally a new Mir back was merged back in that provides v0.1.1.
Mark Shuttleworth has apologized on the behalf of his legal team for one of his employees asserting their trademark rights over a web-site that was critical of Ubuntu's privacy within Unity. At the same time he also apologized over his earlier "Open Source Tea Party" comments for anti-Mir users.
While Mir is big onto integrated testing and was designed from the ground-up this way, performance regressions slipping into the code-base doesn't appear to be incredibly uncommon. Just days after Mir receiving an important performance rendering fix, another commit to Canonical's display server sets out to "fix significant performance issues" with the code-base.
Now with Mark Shuttleworth having announced the Ubuntu 14.04 LTS codename last Friday, a day after the debut of Ubuntu 13.10, this next Ubuntu Linux release is now officially under development.
It was on this day nine years ago that Mark Shuttleworh announced the first Ubuntu Linux release, Ubuntu 4.10 "Warty Warthog", but the conversation this weekend hasn't been about how Ubuntu has advanced the Linux desktop and its adoption for nearly the past decade but rather Mark's comments about anti-Mir Linux users and the disgruntled open-source users/developers as a result.
The latest revision to Mir features an important performance fix.
On Friday when announcing the Ubuntu 14.04 LTS codename, Mark Shuttleworth ruffled some feathers by making some critical comments about the Linux users in opposition to Canonical's Mir Display Server. KDE's Aaron Siego has now challenged Mark to a public and live debate over Mir vs. Wayland.
Mark Shuttleworth has revealed the codename of the Ubuntu 14.04 LTS release while also having some choice words about those criticizing Canonical's Mir Display Server, and comparing them to an Open Source Tea Party.
Now that Ubuntu 13.10 has shipped all eyes for those about the bleeding edge Linux are on the latest developments for Ubuntu 14.04 LTS. One of the most interesting elements of this next Ubuntu Linux release is whether they will ship Mir as the default display server on the desktop.
Canonical is releasing Ubuntu 13.10 today, on the same day Microsoft is shipping Windows 8.1.
With the 1100th revision to Mir's Bazaar repository, Mir graduated to version 0.0.15 and the Mir Server Library (libmirserver) had an ABI bump to version 7.
After a few days of wrangling, the very latest Ubuntu Touch images have the Mir Display Server replacing Android's SurfaceFlinger.
While the Ubuntu 13.10 release is just over one week away, Mir still hasn't officially landed in the Ubuntu Phone images as the new display server. There's been some bugs but it looks like it will now be landing rather soon.
Canonical developers have worked through the weekend in readying Ubuntu Touch with the Unity 8 mobile interface and to be powered by the Mir Display Server.
While Mir won't be part of the default Ubuntu 13.10 desktop, it will be part of Ubuntu Touch 13.10 and development is continuing in a steadfast manner to make it ready for the desktop in 2014. Mir 0.0.13 was released today while bumping the Mir Server library to version 5.
Yesterday it was announced that (X)Mir will not be used in Ubuntu 13.10 by default as was originally planned for the desktop Linux distribution updating this month. Cited as a reason was the multi-monitor support not being ready, but there's also several other user-facing issues present in the land of Mir.
While the Ubuntu 13.10 desktop was expected to ship with Mir/XMir by default for supported configurations, this is no longer going to happen. Ubuntu developers conceded today that Mir/XMir isn't ready for desktop configurations when Ubuntu 13.10 ships later this month.
If you haven't grabbed it yet, the final (and only official) beta of Ubuntu 13.10 is now available while derivatives like Kubuntu and Xubuntu are on their second and final beta releases ahead of the 13.10 "Saucy Salamander" release next month.
While Mir's composite bypass support can dramatically improve the performance for Linux OpenGL games running on the Ubuntu display server, some Intel and AMD users have experienced on-screen corruption and other visual glitches when relying upon XMir since the bypass support was merged.
A new video surfaced today showing Unity 8 atop Mir -- without XMir or Android's SurfaceFlinger -- running on Ubuntu Touch, but right now it's a visually depressing experience.
Ubuntu developers are presently deciding what to do with support for the ReiserFS file-system, up to and including dropping kernel support for the aging but stable file-system.
While the OpenGL gaming performance on XMir/Mir was recently made faster thanks to composite bypass support being committed, the feature doesn't help out non-full-screen applications for rendering faster. To see where the current 2D Linux desktop performance is on Ubuntu 13.10 when using Intel graphics and enabling XMir and the Unity System Compositor, here are some new benchmarks.
The latest feature added to Ubuntu's Mir display server is nested rendering support when using Android.
Support was committed to Mir on Friday for handling Display Power Management Signaling (DPMS) so that monitors will be able to enter down their power-down/sleep state.
For those that didn't notice yesterday, the Ubuntu family has done their first betas for the 13.10 "Saucy Salamander" release.
One day after Canonical developers landed Mir composite bypass support to dramatically improve the performance of full-screen games on Mir/XMir, Mir has picked up another important feature.
During the final day of this week's virtual Ubuntu Developer Summit, upcoming plans for the Mir Display Server were shared as it pertains to performance optimizations and yet-to-be-implemented features.
It's been almost two months since last publishing Intel Haswell virtualization benchmarks, but with the continued evolution of the Linux kernel and the rest of the virtualization stack, here's some new Linux KVM benchmarks from Ubuntu 13.10 in its current form from an Intel Core i7 processor.
Composition bypass support for Mir has landed, which is one of the performance critical features for Mir. Composition bypass can substantially improve the performance of OpenGL games running on XMir now when they are being run in full-screen mode.
Another topic discussed this week during the latest virtual Ubuntu Developer Summit was the release schedule for Ubuntu 14.04, the next Long-Term Support release from Canonical.
