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.
Ubuntu developers are looking at how to bring the Ubuntu SDK for application development to Windows and OS X operating systems.
With the upcoming Linux 3.11 kernel there is basic support for Intel Rapid Start Technology. Ubuntu developers are already figuring out how to utilize this Rapid Start support.
The Canonical team working on the Mir Display Server for Ubuntu Linux released Mir 0.0.10 today. Separately, they're calling for Mir multi-monitor testing in the next few days.
Friday afternoon marked the release of Ubuntu 12.04.3 LTS, the latest point release to the most recent Ubuntu Linux Long-Term Support update.
Yesterday we passed along news of an XMir security issue where using Canonical's X11 transition layer in communicating with the Mir display server, when performing a VT switch the XMir session can still read input from devices. Fortunately, this issue looks to now be resolved.
With Ubuntu Linux still not relying upon systemd, the Upstart event-based init daemon has seen a new release just ahead of the Ubuntu 13.10 feature freeze.
A rather glaring security issue has been present in Canonical's XMir component for its new Mir display server, but there's been very little action in addressing the problem.
The Ubuntu Edge crowd-sourced smart-phone campaign is set to end tonight, but Canonical is short by twenty million dollars on its crowd-funding campaign and there's been no last minute surprises to push the Ubuntu-powered converged device ahead.
Another Virtual Ubuntu Developer Summit is set to take place next week to get a better grasp of the Ubuntu 13.10 goals reached and the work ahead within the Ubuntu ecosystem for the next three to six months.
We know that a lot of Mir improvements/features should land this week with the Ubuntu 13.10 feature freeze being imminent. The first Bazaar commit this week to the Mir Display Server has added in support for per-session display configuration.
Ahead of the Ubuntu 13.10 feature freeze, expect Mir multi-monitor support and composition bypass support to land around next week.
For those following Mir Display Server development now that it's living in Ubuntu 13.10, Mir 0.0.9 has been released.
