Ubuntu 18.04 and 18.10 Hybrid Laptop Users Invited to Test Nvidia PRIME Support

Filed under
Ubuntu

With the release of Ubuntu 18.04 LTS (Bionic Beaver) as the first LTS (Long Term Support) Ubuntu release to ship with the GNOME desktop environment by default instead of Canonical's in-house built Unity desktop, hybrid laptop users with Intel and Nvidia GPUs lost the way Nvidia PRIME worked in the Ubuntu 16.04 LTS (Xenial Xerus) series.

But it looks like some Ubuntu developers like Alberto Milone never stopped looking for a fix, and he and his team have successfully released a patch for the bug causing increased power consumption when using the power saving profile with the Nvidia GPU turned off, as well as the inability to switch between power profiles when logging out.

Debian Patches for Intel's Defects, Canonical to Fix Ubuntu Security Flaws for a Fee

  • Debian Outs Updated Intel Microcode to Mitigate Spectre V4 and V3a on More CPUs

    The Debian Project released an updated Intel microcode firmware for users of the Debian GNU/Linux 9 "Stretch" operating system series to mitigate two of the latest Spectre vulnerabilities on more Intel CPUs.

    Last month, on August 16, Debian's Moritz Muehlenhoff announced the availability of an Intel microcode update that provided Speculative Store Bypass Disable (SSBD) support needed to address both the Spectre Variant 4 and Spectre Variant 3a security vulnerabilities.

    However, the Intel microcode update released last month was available only for some types of Intel CPUs, so now the Debian Project released an updated version that implements SSBD support for additional Intel CPU models to mitigate both Spectre V4 and V3a on Debian GNU/Linux 9 "Stretch" systems.

  • Announcing Extended Security Maintenance for Ubuntu 14.04 LTS – “Trusty Tahr” [Ed: Canonical looking to profit from security flaws in Ubuntu like Microsoft does in Windows.]

    Ubuntu is the basis for the majority of cloud-based workloads today. With over 450 million public cloud instances launched since the release of Ubuntu 16.04 LTS, a number that keeps accelerating on a day-per-day basis since, many of the largest web-scale deployments are using Ubuntu. This includes financial, big data, media, and many other workloads and use cases, which rely on the stability and continuity of the underlying operating system to provide the mission-critical service their customers rely on.

    Extended Security Maintenance (ESM) was introduced for Ubuntu 12.04 LTS as a way to extend the availability of critical and important security patches beyond the nominal End of Life date of Ubuntu 12.04. Organisations use ESM to address security compliance concerns while they manage the upgrade process to newer versions of Ubuntu under full support. The ability to plan application upgrades in a failsafe environment continues to be cited as the main value for adoption of ESM. With the End of Life of Ubuntu 14.04 LTS in April 2019, and to support the planning efforts of developers worldwide, Canonical is announcing the availability of ESM for Ubuntu 14.04.

  • Canonical Announces Ubuntu 14.04 LTS (Trusty Tahr) Extended Security Maintenance

    Canonical announced today that it would extend its commercial Extended Security Maintenance (ESM) offering to the Ubuntu 14.04 LTS (Trusty Tahr) operating system series starting May 2019.

    Last year on April 28, 2017, when the Ubuntu 12.04 LTS (Precise Pangolin) operating system series reached end of life, Canonical announced a new way for corporate users and enterprises to receive security updates if they wanted to keep their current Ubuntu 12.04 LTS installations and had no plans to upgrade to a newer LTS (Long Term Support) release. The offering was called Extended Security Maintenance (ESM) and had a great success among businesses.

  • Fresh Snaps from August 2018

    Another month passes and we’ve got a collection of applications which crossed our “desk” (Twitter feed) during August 2018. We have a mix of social tools, music creation and curation software, password storage systems, developer tools and some fun too. Take a look down the list, and discover something new today.

  • Financial services: escaping the burning platform

    The financial services industry is standing on a burning platform, it’s time to jump to safety or suffer the consequences.

    The platform in this picture is the legacy infrastructure that dominates their IT organisations. From ageing servers and a dwindling workforce that’s even capable of running these monoliths, the pressure to change, for many, would have already forced a leap to safety.

    Unfortunately for banks, that’s not the only pressure they are under. Challengers have emerged where there were none before and changes in regulation are forcing a dramatic rethink of how infrastructure can be approached and what technologies are available for them to use. Compounded by a growing demand from customers for services that are modern, always-on, safe, and simple to use, and you’ve got a perfect storm that FS is having to navigate.

  • Leading the Vanilla design system

    We currently have 47 websites from marketing to cloud applications under our suite of products here at Canonical, the Vanilla squad are working through migrating these sites to our latest release.

    We’ve completed 60% of the migration and are making good headway. Once complete, our codebase will be unified across our sites making it easier for our front-end developers to jump between projects. And from a design perspective we will have a consistent look and feel.

  • Lubuntu Switching To VLC, KDE 5 LibreOffice Frontend

    Lots of changes are happening in the Lubuntu camp.

    It's been busy in the Lubuntu space recently, the Ubuntu derivative that's historically shipped with the LXDE desktop environment. Most notably, Lubuntu 18.10 switching to LXQt by default over LXDE, while the LXQt spin has been experimental up to this point.

    Lubuntu is also planning to switch to Wayland and as part of that to port Openbox to run on the Mir-Wayland code. But this work isn't happening overnight but rather is a goal to have done by Lubuntu 20.10 in 2020.

Robots that run Ubuntu

Ubuntu

The home for innovators, Ubuntu is a place where developers can create what previously lived solely in the realms of fiction. The internet of things, the cloud, and robots are world changing technologies and they’re all running Ubuntu.

With an estimated worldwide spending figure of $103bn by 2020, according to IDC, the field of robotics is one of those transformative industries that is really gaining traction, and it’s not just the manufacturing industry that’s using them, robots are everywhere.

From collecting tennis balls, to social robots, agriculture and retail. Robots are making our lives easier and it turns out that a large amount of them are an Ubuntu robot.

Don’t just take my word for it though, below is a list of of just some of the cool and brilliant ways Ubuntu is being used in the field of robotics.

Canonical Outs New Linux Kernel Live Patch for Ubuntu 18.04 LTS and 16.04 LTS

Filed under
Ubuntu

Coming hot on the heels of the latest Linux kernel security update released by Canonical on Tuesday, the new Linux kernel live patch security update fixes a total of five security vulnerabilities, which are documented as CVE-2018-11506, CVE-2018-11412, CVE-2018-13406, CVE-2018-13405, and CVE-2018-12233.

These include a stack-based buffer overflow (CVE-2018-11506) discovered by Piotr Gabriel Kosinski and Daniel Shapira in Linux kernel's CDROM driver implementation, which could allow a local attacker to either execute arbitrary code or cause crash the system via a denial of service.

    It has already been removed from the official list of Debian mirrors. Please update your sources.list to point to an alternative sooner rather than later.

  • Debian/TeX Live binaries update 2018.20180907.48586-1

    A new set of TeX Live binaries has been uploaded to Debian, based on the Subversion status as of 7 September (rev 48586). Aim was mostly fixing a bug of (x)dvipdfm(x) introduced by a previous upload. But besides fixing this, it also brought the new version of dvisvgm (2.5) into Debian.

    [...]

    The current sources also contain another cherry picked bug fix for dvipdfmx, but unfortunately I will have to stop now using the subversion tree as is, due to the inclusion of an intermediate luatex release I am not convinced I want to see in Debian before the proper release of TeX Live 2019. That means, from now on I have to cherry pick till the next TeX Live release.

Security: Updates, NewEgg Breach, "Master Password" and CLIP OS

  • Security updates for Thursday
  • NewEgg cracked in breach, hosted card-stealing code within its own checkout

    The popular computer and electronics Web retailer NewEgg has apparently been hit by the same payment-data-stealing attackers who targeted TicketMaster UK and British Airways. The attackers, referred to by researchers as Magecart, managed to inject 15 lines of JavaScript into NewEgg's webstore checkout that forwarded credit card and other data to a server with a domain name that made it look like part of NewEgg's Web infrastructure. It appears that all Web transactions over the past month were affected by the breach.

  • "Master Password" Is A Password Manager Alternative That Doesn't Store Passwords
    Master Password is a different way of using passwords. Instead of the "know one password, save all others somewhere" way of managing passwords used by regular password managers, Master Password's approach is "know one password, generate all the others".
  • French cyber-security agency open-sources CLIP OS, a security hardened OS
    The National Cybersecurity Agency of France, also known as ANSSI (Agence Nationale de la Sécurité des Systèmes d'Information), has open-sourced CLIP OS, an in-house operating system its engineers had developed to address the needs of the French government administration. In a press release, ANSSI described CLIP OS as a "Linux-based operating system [that] incorporates a set of security mechanisms that give it a very high level of resistance to malicious code and allow it to protect sensitive information."

What Apps Can You Actually Run on Linux?

Most Linux distributions include Mozilla Firefox as the default web browser. Google also offers an official version of Google Chrome for Linux, and you can even get an “unbranded” open-source version of Chrome named Chromium. Pretty much everything inside your web browser should “just work” in Linux. Netflix now works normally in both Firefox and Chrome on Linux thanks to added support for its DRM. Adobe Flash has become less common on the web but is also available for Linux. It’s included with Chrome, just like on Windows, and you can install it separately for Firefox or Chromium. Linux doesn’t support some older browser plug-ins like Silverlight, but those are no longer widely used on the web. As the desktop PC world has shifted more and more to online, web-based software, Linux has become easier to use. If an application you want to run has a web version, you can use it on Linux.

    Ubuntu 18.04 shipped with two issues for Intel+Nvidia hybrid graphics users: an increase in power consumption when the discrete GPU is off, and the inability to switch between power profiles with a simple logout (a restart is currently required). These issues are caused by changes in logind, Nvidia drivers packaging (which is now more granular), and the migration from LightDM to GDM3, and they were fixed in Ubuntu 18.10 Cosmic Cuttlefish.
