19-Way CPU Comparison On Ubuntu With Linux 4.15

Ubuntu

Following the release of the Linux 4.15 kernel with KPTI and Retpoline introduction, many Phoronix readers were interested in seeing a fresh Linux CPU performance comparison. For those reasons plus in preparing for the Raven Ridge testing, here are benchmarks of 19 different systems when using Ubuntu x86_64 with the Linux 4.15 stable kernel.

An assortment of 19 different systems from old to new and from low-end to high-end were tested, ranging from old AMD A10 Kaveri APUs to the high-end AMD EPYC 7601 server processor, with a similar breadth of CPUs tested on the Intel side. Again, these tests are mostly being done for reference purposes. And in the days ahead will be a larger low-end-focused CPU comparison for the upcoming Ryzen 3 2200G / Ryzen 5 2400G Linux benchmarking.

Canonical Invites Ubuntu Linux Users to Test Video Playback in Ubuntu 18.04 LTS

Filed under
Linux
Ubuntu

While Canonical already implemented hardware-accelerated video playback support for Intel CPUs in the current release of the operating system, Ubuntu 17.10 (Artful Aardvark), it would appear that plan on extending it to other types of processors, display servers, and video players.

In a recent call for testing, Canonical urges those who are already running the Ubuntu 18.04 LTS (Bionic Beaver) operating system on their personal computers to test the video playback performance with apps like MPV or Totem (GNOME Videos), as well as the Wayland or Xorg display servers, and report any issues.

Ubuntu 18.04 LTS Daily Builds Now Use Xorg by Default Instead of Wayland

Filed under
Ubuntu

The decision to switch the display server from Wayland back to Xorg by default for Ubuntu 18.04 LTS "Bionic Beaver" was taken a few weeks ago when Canonical's Director of Ubuntu Desktop Will Cooke said the main reasons are the inability for Wayland to support screen sharing and remote desktop services, as well as recoverability from GNOME Shell crashes.

As of today, the Ubuntu 18.04 LTS daily builds are using Xorg as default display server, but you can still use the Wayland session if you manually select it from the login screen. "The default session has now been switched back to use Xorg by default. Wayland is still installed and can be selected from the login screen," says Will Cooke in a recent Ubuntu weekly update.

With many of you likely upgrading to Ubuntu 18.04 LTS upon release and the recommendation to use disk encryption as important as ever on any important system especially laptops/ultrabooks, here are some fresh benchmarks using a development snapshot of Ubuntu 18.04 "Bionic Beaver" and looking at the current performance overhead of using the current "home directory encryption" and "full disk encryption" options available to Ubuntu Linux users.

  • Ubuntu 18.04 LTS Could Come with Snap Apps Preinstalled

    Ubuntu devs propose shipping Snap apps by default in Ubuntu 18.04 LTS, though decisions need to be made around policy and maintainability first.

  • Policies for snaps shipped with Ubuntu being created

    Ever since Ubuntu 16.04, which launched just under two years ago, Canonical has made it possible to install snap packages. Snaps are self-contained applications that include dependencies for the software to run, they also bolster security by giving developers more control over the update process and the dependencies. Now, Canonical is trying to formulate policies around snaps which it wants to ship by default in future versions of Ubuntu.

  • Ubuntu Desktop weekly update – February 2, 2018

    As you might have already read, we’ve taken the decision to ship Xorg by default in Bionic 18.04 LTS. The Wayland session will still be available as an option at login. You can read more about that here.

    The Ubuntu Dock extension has been rebased on the latest upstream master and we’ve added some bug fixes. This has now been uploaded to Bionic.

    We’ve made some good progress in reducing GNOME Shell’s CPU usage where we discovered that Shell is repainting unchanged panel and dock every time an application windows repaints. We’ve proposed some upstream fixes.
    There’s another fix upstream for helping menus fade out cleanly on close. We have a checklist of issues which are making GNOME Shell stutter and we’re starting with the multi-monitor issues.

  • Ubuntu Insights: Snapcraft Summit summary – day 5

    It was amazing to see the kind of collaboration that snapcraft brings to the Linux world. The engineering, advocacy, desktop and design teams of snapcraft spent every day working next to developers from Microsoft, Skype, Slack, Electron, CircleCI, Plex and ROSHub on improving the experience to deliver their applications continuously, in a way that fits perfectly into their release process and that will make their users feel secure and confident. It was great to see the mix of languages, cultures and operating systems, all working together to solve this common delivery problem, now with a tool that is very open and welcoming, and that evolves quickly as new applications bring new requirements.

  • Ubuntu 18.04 LTS Might Ship With OpenJDK 10, Transition To OpenJDK 11

    Canonical's Tiago Daitx has laid out a proposal today for having an OpenJDK stable release update exception for the upcoming Ubuntu 18.04 LTS "Bionic Beaver" to reduce their long-term maintenance burden.

    Right now in the Ubuntu 18.04 development archive is OpenJDK 8, but the hope is this Ubuntu Long Term Support release will default to OpenJDK 10 as its Java JRE/JDK and then replace it with OpenJDK 11 after its release. If they stick to OpenJDK 8, Canonical will have more of a maintenance burden in the years ahead for maintaining this Java Development Kit version for this Ubuntu Long Term Support.

  • Ubuntu 18.04 Minimal Spin Down To ~30MB Compressed / ~81MB On Disk

    For those using Ubuntu Minimal images for containers/Docker, assembling your own base distribution, setting up an embedded Linux environment, or related use-cases, the minimal images for the upcoming Ubuntu 18.04 LTS release will be even smaller.

  • RFC: Ubuntu 18.04 LTS Minimal Images

    In last year's AskHN HackerNews post, "Ask HN: What do you want to see in Ubuntu 17.10?", and the subsequent treatment of the data, we noticed a recurring request for "lighter, smaller, more minimal" Ubuntu images.

    This is particularly useful for container images (Docker, LXD, Kubernetes, etc.), embedded device environments, and anywhere a developer wants to bootstrap an Ubuntu system from the smallest possible starting point.

  • Snapcraft Summit summary – day 3

    Strictly-confined snaps can only access specific areas on disk that are defined by the interfaces they utilize. This works well, but can occasionally be somewhat inflexible. For example, if you want your snap to access something in /opt, you’re a bit out of luck as there’s no interface that covers this type of access. How cool would it be for you as a user to gain more fine-grained control over this, where you can say “yes, I want this snap to access that file in /opt“? With this ability, even the home interface would no longer be as necessary as it is today! James Henstridge and Jamie Strandboge are working on exactly this, progressing toward using xdg-desktop-portal. James spent the day hacking on user mounts, which is a prerequisite for this whole story.

    Canonical, the company behind Ubuntu, announces today that Skype is now available as a snap, the universal Linux app packaging format. Available as of today, the release means that Skype can deliver its communication service to a wider range of Linux users, including millions on Ubuntu.

  • Now Just Five Men Own Almost as Much Wealth as Half the World’s Population

    Why Do We Let Unqualified Rich People Tell Us How To Live? Especially Bill Gates!

    In 1975, at the age of 20, Bill Gates founded Microsoft with high school buddy Paul Allen. At the time Gary Kildall’s CP/M operating system was the industry standard. Even Gates’ company used it. But Kildall was an innovator, not a businessman, and when IBM came calling for an OS for the new IBM PC, his delays drove the big mainframe company to Gates. Even though the newly established Microsoft company couldn’t fill IBM’s needs, Gates and Allen saw an opportunity, and so they hurriedly bought the rights to another local company’s OS — which was based on Kildall’s CP/M system. Kildall wanted to sue, but intellectual property [sic] law for software had not yet been established. Kildall was a maker who got taken.

    So Bill Gates took from others to become the richest man in the world. And now, because of his great wealth and the meritocracy myth, MANY PEOPLE LOOK TO HIM FOR SOLUTIONS IN VITAL AREAS OF HUMAN NEED, such as education and global food production.
