Mir Has Partial Support For The NVIDIA Proprietary Driver, X11 Support Remains WIP

Filed under
Ubuntu

Canonical's team responsible for continuing to advance the Mir display server has been making good progress this summer on fleshing out some missing functionality.

This week partial support for the NVIDIA proprietary driver was merged. In particular, the EGLStreams platform support. This is the initial bits for getting the NVIDIA proprietary driver to play along with Mir, but isn't yet the full implementation required to get OpenGL clients working on Mir with the NVIDIA driver. That work is still being pursued and is a work-in-progress. Mir's path for NVIDIA support is similar to that of the Wayland compositors with needing to implement EGLStreams and there not yet being any new Unix device memory allocation API that NVIDIA has been pushing for years to create the best of both worlds -- in terms of EGLStreams and GBM APIs for all driver vendors to agree upon.

  • Lubuntu Planning Switch To Wayland, Porting Openbox To Mir

    Ubuntu derivative Lubuntu that is now using the LXQt desktop environment has laid out more of their plans to switch over to Wayland rather than the existing X.Org based session.

    In order to achieve their Wayland support with the LXQt desktop, they intend to port the Openbox window manager to using the Mir display server and also leveraging QtLayerShell. Mir, of course, has been focused on Wayland compatibility the past year and is becoming quite solid as of late with its core Wayland protocol support.

  • Lubuntu Development Newsletter #9

    We’ve been polishing the desktop more, but work has been blocked by the still ongoing Qt transition.

    The 16.04 to 18.04 upgrade has now been enabled! Please do let us know if there’s any issues. Here’s a video we made when 17.04 went End of Life; the instructions are still current.

    Our main developer, Simon Quigley, became an Ubuntu Core Developer this past Monday! He now has access to the entire Ubuntu archive.

Canonical/Ubuntu: Newsletter, Kubernetes and Design

  • Deploying Kubernetes on Public Clouds is hard – or is it?

    Recently, there’s been talk about how Kubernetes has become hard to deploy and run on virtual substrates such as those offered by the public clouds. Indeed, the cloud-specific quirks around infrastructure provisioning, including storage, networking assets such as load balancers, and overall access control (IAM) differs from cloud to cloud provider. It is safe to assume that it also differs between your on-prem IaaS implementation or virtualized infrastructure and the public cloud APIs.

    With all the public Container-as-a-Service (CaaS) offerings available to you, why would you deploy Kubernetes to a generic IaaS substrate anyway? There are many reasons for doing so.

Brasero – Disk Burning App for Ubuntu, Linux Mint

Filed under
Ubuntu

Brasero is a very simple disk burning GNOME app available for all Linux distributions. However, for sometime it has been removed from the standard Ubuntu OS images. The main reason behind is the low usage of DVD, CD storage mediums in recent times. However, if you still wants to burn some disks, erase or re-write some disks, you can still install Brasero in Ubuntu and other Linux distributions.

  • [ANNOUNCE] wayland-1.15.93

    The RC1 release candidate for wayland 1.16 is now available.

  • Wayland 1.16 & Weston 5.0 Release Candidates For Testing

    Derek Foreman of Samsung's Open-Source Group put out the release candidates on Friday for the upcoming Wayland 1.16 release as well as the Weston 5.0 reference compositor.

    The Wayland 1.16 release candidate hasn't seen any changes over the earlier development release besides updating the contributor documentation to reflect that Gitlab is now used for handling merge requests. The Wayland 1.16 cycle overall was quite light but earlier in the cycle it did see build system updates, dropping of the wl_buffer definition, and the protocol now allows a zero physical size output.

  • XDG Shell Stable Supported by Mir

    Support for the stable XDG Shell protocol has just landed in Mir, and it will ship with the next release. It will eventually replace XDG Shell unstable v6 as the primary way in which Wayland applications create traditional style windows. You can get it now in our development PPA: ppa:mir-team/dev.

  • Mir Now Supports XDG Shell Stable

    Canonical developers continue working on advancing the Mir display server's support for Wayland.

    The latest Wayland enhancement to Mir is on supporting the stable version of the XDG Shell protocol. XDG-Shell is the protocol for improved management of Wayland surfaces including for minimization of windows, dragging, resizing, and other desktop-aligned tasks. XDG Shell also defines protocol around transient windows like pop-up menus.

GNOME: NVMe Firmware and GSConnect

  • Richard Hughes: NVMe Firmware: I Need Your Data
    In a recent Google Plus post I asked what kind of hardware was most interesting to be focusing on next. UEFI updating is now working well with a large number of vendors, and the LVFS “onboarding” process is well established now. On that topic we’ll hopefully have some more announcements soon. Anyway, back to the topic in hand: The overwhelming result from the poll was that people wanted NVMe hardware supported, so that you can trivially update the firmware of your SSD. Firmware updates for SSDs are important, as most either address data consistency issues or provide nice performance fixes.
  • Gnome Shell Android Integration Extension GSConnect V12 Released
    GSConnect v12 was released yesterday with changes like more resilient sshfs connections (which should make browsing your Android device from the desktop more reliable), fixed extension icon alignment, along with other improvements. GSConnect is a Gnome Shell extension that integrates your Android device(s) with the desktop. The tool makes use of the KDE Connect protocol but without using any KDE dependencies, keeping your desktop clean of unwanted packages.

Anyway, a new version of GSconnect popped out this week. GSconnect v12 adds a nifty new features or two, as well as a few fixes here, and a few UI tweaks there.

Red Hat Leftovers

  • Red Hat Advances Container Storage
    Red Hat has moved to make storage a standard element of a container platform with the release of version 3.1 of Red Hat OpenShift Container Storage (OCS), previously known as Red Hat Container Native Storage. Irshad Raihan, senior manager for product marketing for Red Hat Storage, says Red Hat decided to rebrand its container storage offering to better reflect its tight integration with the Red Hat OpenShift platform. In addition, the term “container native” continues to lose relevance given all the different flavors of container storage that now exist, adds Raihan. The latest version of the container storage software from Red Hat adds arbiter volume support to enable high availability with efficient storage utilization and better performance, enhanced storage monitoring and configuration via the Red Hat implementation of the Prometheus container monitoring framework, and block-backed persistent volumes (PVs) that can be applied to both general application workloads and Red Hat OpenShift Container Platform (OCP) infrastructure workloads. Support for PVs is especially critical because to in the case of Red Hat OCS organizations can deploy more than 1,000 PVs per cluster, which helps to reduce cluster sprawl within the IT environment, says Raihan.

  • Mixing software development roles produces great results
    Most open source communities don’t have a lot of formal roles. There are certainly people who help with sysadmin tasks, testing, writing documentation, and translating or developing code. But people in open source communities typically move among different roles, often fulfilling several at once. In contrast, team members at most traditional companies have defined roles, working on documentation, support, QA, and in other areas. Why do open source communities take a shared-role approach, and more importantly, how does this way of collaborating affect products and customers? Nextcloud has adopted this community-style practice of mixing roles, and we see large benefits for our customers and our users.
  • FOSS Project Spotlight: SIT (Serverless Information Tracker)
    In the past decade or so, we've learned to equate the ability to collaborate with the need to be online. The advent of SaaS clearly marked the departure from a decentralized collaboration model to a heavily centralized one. While on the surface this is a very convenient delivery model, it simply doesn't fit a number of scenarios well. As somebody once said, "you can't FTP to Mars", but we don't need to go as far. There are plenty of use cases here on Earth that are less than perfectly suited for this "online world". Lower power chips and sensors, vessel/offshore collaboration, disaster recovery, remote areas, sporadically reshaping groups—all these make use of central online services a challenge. Another challenge with centralization is somewhat less thought of—building software that can handle a lot of concurrent users and that stores and processes a lot of information and never goes down is challenging and expensive, and we, as consumers, pay dearly for that effort. And not least important, software in the cloud removes our ability to adapt it perfectly for use cases beyond its owner's vision, scope and profitability considerations. Convenience isn't free, and this goes way beyond the price tag.

    AddressSanitizer has worked in rr for a while. I just found that LeakSanitizer wasn't working and landed a fix for that. This means you can record an ASAN build and if there's an ASAN error, or LSAN finds a leak, you can replay it in rr knowing the exact addresses of the data that leaked — along with the usual rr goodness of reverse execution, watchpoints, etc. Well, hopefully. Report an issue if you find more problems.
  • Oracle Open-Sources GraphPipe to Support ML Development
    Oracle on Wednesday announced that it has open-sourced GraphPipe to enhance machine learning applications. The project's goal is to improve deployment results for machine learning models, noted Project Leader Vish Abrams. That process includes creating an open standard. The company has a questionable relationship with open source developers, so its decision to open-source GraphPipe might not receive a flood of interest. Oracle hopes developers will rally behind the project to simplify and standardize the deployment of machine learning models. GraphPipe consists of a set of libraries and tools for following a deployment standard.
  • OERu makes a college education affordable
    Open, higher education courses are a boon to adults who don’t have the time, money, or confidence to enroll in traditional college courses but want to further their education for work or personal satisfaction. OERu is a great option for these learners. It allows people to take courses assembled by accredited colleges and universities for free, using open textbooks, and pay for assessment only when (and if) they want to apply for formal academic credit. I spoke with Dave Lane, open source technologist at the Open Education Resource Foundation, which is OERu’s parent organization, to learn more about the program. The OER Foundation is a nonprofit organization hosted by Otago Polytechnic in Dunedin, New Zealand. It partners with organizations around the globe to provide leadership, networking, and support to help advance open education principles.
