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.
As expected with Canonical's plans to land the Mir Display Server with XMir in Ubuntu 13.10 where Unity 7 will run atop XMir by default for supported configurations, the various components have now landed in the Ubuntu 13.10 "Saucy" main archive.
There's been a slight boost in the crowd-funded Ubuntu Edge smart-phone / converged device project with now being up to $9.175 million dollars in funding.
Canonical's Mir Display Server for Ubuntu Linux has proper support for handling switching to virtual terminals.
Bloomberg LP has come forward as the only corporate backer to date of the Ubuntu Edge smart-phone project.
With there being experimental XMir-based Xubuntu 13.10 images available for the Xfce desktop spin and a request going out for testing, I ran some Phoronix performance tests to compare the XMir performance penalty for 2D and 3D workloads.
Xubuntu, the Xfce-based flavor of Xubuntu, is presently evaluating the use of Canonical's Mir display server via the XMir X11 transition layer. For helping in the process and testing, the Ubuntu derivative has made public some Xubuntu XMir images.
One of the feature limitations of using the Mir Display Server up to this point has been when using multiple monitors (or say a laptop connected to a projector) the only display configuration possibility is using a cloned mode whereby the screens are the same. Canonical's Mir developers have begun working on improved multi-monitor handling.
