Here’s Ubuntu 19.10’s New Default Wallpaper

Filed under
Ubuntu

The new desktop background for Ubuntu 19.10 was uploaded to a bug report on Launchpad where, as tradition dictates, it’s also available to download.

As we’ve come to expect from Ubuntu wallpapers of late, the new drape bears an artistic depiction of the latest Ubuntu codename mascot, which for this release is an “Ermine”, or white stoat...

Ubuntu 19.10 ‘Eoan Ermine’ will be released on October 18, 2019. And as well as this wonderful new wallpaper it offers Linux Kernel 5.3, a light Yaru GTK theme and the all-new GNOME 3.34 release.

Ubuntu

As eagle-eyed readers may have noted, Vulture Central UK is on the move. Our migratory path has led us to London's Grays Inn Road and, well, you can see what was waiting for us.

We normally like to feature Windows machines in various states of distress, be it a Tesco or Boots self-service till, or the odd railway terminal having a very, very bad day.

Today, courtesy of BT's InLinkUK, we have a Linux-based device caught with its pants down on our doorstep.

InLinkUK is an outfit that plops ad-slinging screens on the pavement, which lure punters with the promise of connectivity. Or, in this case, an insight into the OS on which the things actually run.

Canonical Fixes Linux 4.15 Kernel Regression in Ubuntu 18.04 LTS and 16.04 LTS

Filed under
Ubuntu

Earlier this month, Canonical published major Linux kernel security updates for all supported Ubuntu Linux operating systems, addressing no less than 28 security vulnerabilities. However, one of the patches also introduced a regression causing the Linux kernel 4.15 on Ubuntu 18.04 LTS and Ubuntu 16.04 LTS systems to crash when handling fragmented packets.

"USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. We apologize for the inconvenience," said Canonical in the security advisory.

My Ubuntu Reached EOL, What Should I Do?

Filed under
Ubuntu

If your Ubuntu version reached its End of Life (EOL), it will not install software anymore. You can still use the system without time limit but you cannot get more applications nor security updates. This article explains with example to take care of Ubuntu 14.10 "Utopic Unicorn" which has been EOL since 2015 so it can install programs once again (but without updates). This tutorial can be used for other EOLed versions of Ubuntu for example 10.10 or 17.04. I hope this helps.

Each Ubuntu release has support duration, meaning, a certain period of time where Canonical provides software repository (including security updates) for it. When the support duration ended, it is called End Of Life, meaning Canonical deletes the repository (including security updates) for it. Once your Ubuntu system reached EOL, you cannot install software anymore nor receive any updates. For example, in 2019, versions considered EOL are 12.10, 14.10, and 17.04, among others.

Ubuntu 19.10 "Eoan Ermine" Promises More Boot Speed Improvements

Filed under
Ubuntu

According to Colin Ian King, the Ubuntu Kernel Team worked hard during the past few months to find a faster compression/decompression algorithm for the upcoming Ubuntu 19.10 (Eoan Ermine) operating system, which will hit the streets later this fall on October 17th.

The Ubuntu Kernel Team benchmarked six compression methods for the initramfs, including BZIP2, GZIP, LZ4, LZMA, LZMO and XZ, to measure the loading time of the Linux kernel, as well as the decompression time. The benchmarking was conducted on x86 configurations using the x86 TSC (Time Stamp Counter).

  • Ubuntu 19.10 To Boot Faster Thanks To LZ4 Compression

    Ubuntu's kernel team has decided to switch to LZ4 kernel image compression beginning with Ubuntu 19.10 in order to speed-up the boot times.

    After evaluating the different compression options for the kernel image, the Ubuntu developers decided to make use of LZ4 on supported architectures for the kernel image and initramfs. Even with slower rotational storage, the much faster decompression times of LZ4 should yield benefit.

  • Ubuntu 19.10 Will Boot Faster Thanks to LZ4 Compression

    Ubuntu 19.10 boot times from installation media will be faster thanks to the use of LZ4 decompression for kernel and initramfs.

Ubuntu 19.10 Switching to a Full Light Theme, Ditching Dark Headerbars

Filed under
Ubuntu

The de-facto Ubuntu artwork team, made up of community enthusiasts hacking on the Yaru GTK theme, have been given the nod to invert the light Yaru theme’s header bar colour.

It means that windows which which currently looks like this:

Think it looks a lot like Adwaita, the upstream GNOME GTK theme? That’s because in a roundabout way the Yaru theme is the Adwaita theme, just with a batch of medications.

Dark header bars and positive accent colours were used to give the Adwaita base an Ubuntu flavoured topping.

But no more.

Ubuntu Yaru Theme Might Get A Full Light Version

Filed under
Ubuntu

Yaru theme might get a full light theme (and a full dark theme that already exists, but with further refinements) instead of the mixed theme that's currently default in Ubuntu.
While users have been voicing their opinion about the need of using a fully light theme with Ubuntu by default, that's not why there are talks to have a Yaru light theme. Instead, it looks like there are issues with the headerbar buttons lack of contrast compared to the background, and this is where the Yaru Light idea comes from.
Feichtmeier, a Yaru theme contributor, sums up the issues with using a mixed theme (light theme with dark headerbar), including in the argument that Gtk is not ready for an inverted headebar, and that "in a normally lightened room at day the dark headerbar is worse usability wise than a light headerbar", also adding that basically all platforms or toolkits use a full light or full dark theme for day/night.

An Easy Fix for a Stupid Mistake

I waited a long time for Mageia 7 and for OpenMandriva Lx 4. When both distros arrived, I was very happy. But new distros bring changes, and sometimes it is not easy to adapt. Mageia 7 has been rock-solid: it is doing a great job in my laptop and both in my daughter's desktop and in mine. There is one thing, though. I have been avoiding a strange mesa update that wants to remove Steam. OpenMandriva is also fantastic, but this new release provided options like rock, release, and rolling. When I first installed the distro, I chose rock because I was shying away from the rolling flavor. Eventually, I had to move to rolling because that was the only way in which I could manage to install Steam in both my laptop and desktop machines. Read more

    There's an exciting patch set to GNOME Shell and Mutter now pending for finally wiring up the full-screen unredirected display / full-screen bypass compositing for helping the performance of full-screen games in particular on Wayland. GNOME on X11 has long supported the full-screen compositing bypass so the window manager / compositor gets out of the way when running full-screen games/applications. That support under Wayland hasn't been in place and thus there is a performance hit for full-screen Wayland-native software. But now thanks to Red Hat's Jonas Ådahl, that infrastructure now appears to be ready.

  • Kernel Address Space Isolation Still Baking To Limit Data Leaks From Foreshadow & Co

    In addition to the work being led by DigitalOcean on core scheduling to make Hyper Threading safer in light of security vulnerabilities, IBM and Oracle engineers continue working on Kernel Address Space Isolation to help prevent data leaks during attacks. Complementing the "Core Scheduling" work, Kernel Address Space Isolation was also talked about at this week's Linux Plumbers Conference in Lisbon, Portugal. The address space isolation work for the kernel was RFC'ed a few months ago as a feature to prevent leaking sensitive data during attacks like L1 Terminal Fault and MDS. The focus on this Kernel ASI is for pairing with hypervisors like KVM as well as being a generic address space isolation framework.

  • The Linux Kernel Is Preparing To Enable 5-Level Paging By Default

    While Intel CPUs aren't shipping with 5-level paging support, they are expected to be soon and distribution kernels are preparing to enable the kernel's functionality for this feature to extend the addressable memory supported. With that, the mainline kernel is also looking at flipping on 5-level paging by default for its default kernel configuration. Intel's Linux developers have been working for several years on the 5-level paging support for increasing the virtual/physical address space for supporting large servers with vast amounts of RAM. The 5-level paging increases the virtual address space from 256 TiB to 128 PiB and the physical address space from 64 TiB to 4 PiB. Intel's 5-level paging works by extending the size of virtual addresses to 57 bits from 48 bits.

Releasing Slax 9.11.0

New school year has started again and next version of Slax is here too :) this time it is 9.11.0. This release includes all bug fixes and security updates from Debian 9.11 (code name Jessie), and adds a boot parameter to disable console blanking (console blanking is disabled by default). You can get the newest version at the project's home page, there are options to purchase Slax on DVD or USB device, as well as links for free download. Surprisingly for me we skipped 9.10, I am not sure why :) I also experimented with the newly released series of Debian 10 (code name Buster) and noticed several differences which need addressing, so Slax based on Debian 10 is in progress, but not ready yet. Considering my current workload and other circumstances, it will take some more time to get it ready, few weeks at least.
