Slackware-Based SlackEX Linux Now Ships with Latest Enlightenment Desktop

Filed under
Slack

Based on Slackware 14.2, the new SlackEX Linux release drops the lightweight Xfce desktop environment for the even more lighter and beautiful Enlightenment desktop environment/window manager. In fact, SlackEX appears to be the only live system that uses the latest Enlightenment release, version 0.24.2.

But that's not all that' new in the latest SlackEX Linux release, which is now powered by the Linux 5.9 kernel series. This not only means better hardware support, but it also means you won't find another Slackware-based live system running Linux kernel 5.9.

Ktown becomes Vtown

Filed under
KDE
Slack

So it is finally happening.
On US Election Day 2020, Pat Volkerding added “vtown” into the ‘testing’ directory of Slackware-current.

The “vtown” in Slackware is essentially my ‘ktown’ repository containing KDE Plasma5 plus its dependencies, with a few exceptions, a number of my packages removed, some caveats and a couple of renamed packages.

A lot of useful information from early adopters can already be found on linuxquestions.org in the dedicated thread about vtown.

One of the benefits of this testing version of Plasma5 in Slackware is the merging of several Slackware and ktown packages.
Mostly because I needed to provide Qt5-supporting versions of existing Slackware packages, I needed different names for the ‘ktown’ versions that I was going to provide. I could not risk that people would end up with old Slackware Qt4 based packages which would break Plasma5.
So to avoid clashing with packages like “plasma-nm”, “attica”, “baloo”, “kscreen” etc… I had to use alternative package names like “plasma5-nm”, “attica-framework”, “baloo5”, “kscreen2” and several (actually, many) more.
Here is the full list of my packages that got merged back into packages with the original Slackware names...

  • Accessibility audit of Vanilla framework | Ubuntu

    The team behind the Vanilla Framework has a background in development, UX and Visual Design. We all care about accessibility, but none of us is an accessibility expert.

    We were interested in evaluating how well the framework complies with accessibility standards. We decided to start with an internal audit, fix any issues we find, then look for a third-party service to evaluate the framework from the perspective of real-world users with disabilities

The Earliest Linux Distros: Before Mainstream Distros Became So Popular

Filed under
GNU
Linux
Slack

In here we have tried to explore how the idea of popular distros such as Red Hat, Debian, Slackware, SUSE, Ubuntu and many others came into being after the first Linux kernel became available.

As Linux was initially released in the form of a kernel in 1991, the distros we know today was made possible with the help of numerous collaborators throughout the world with the creation of shells, libraries, compilers and related packages to make it a complete Operating System.

LibreOffice 6.4.5 finally for Slackware 14.2

Filed under
LibO
Slack

The Document Foundation recently released version 7.0.0 of their Libre Office suite of applications. The packages for Slackware-current can be found in my repository. But the situation for Slackware 14.2 used to be different – I got stuck after LibreOffice 6.2 because the newer source releases (6.3 and onwards) require versions of system software that our stable Slackware 14.2 platform does not offer.

From time to time during the last year, when there was time and the build box was not compiling packages, I messed around with the libreoffice.SlackBuild script in futile attempts to compile recent versions of LibreOffice on Slackware 14.2. I failed all the time.
Until last week. After I had uploaded the new KDE Plasma5 packages to ‘ktown‘, I had an epiphany and decided to use a new approach. What I did was: question all the historic stuff in the SlackBuild script that got added whenever I needed to work around compilation failures; and accept that the compilation needs newer versions of software than Slackware 14.2 offers. The first statement meant that I disabled patches and variable declarations that messed with compiler and linker; and for the second statement I stuck to a single guideline: the end product, if I were able to compile a package successfully, has to run out of the box on Slackware 14.2 without the need to update any of the core Slackware packages.

Porteus 5.0-rc2 Released: Slackware-Based Fast And Portable Linux Distro

Filed under
Linux
Slack

More than a year later, the Dev team of Porteus Linux has finally announced the second release candidate (RC-2) for its upcoming version 5.0. This means you can now try the new testing version Porteus 5.0-rc2.

For those who don’t know, Porteus is based on one of the oldest Linux distros, Slackware. It was also formerly known as Slax remix when it started as a community remix of Slax OS.

Porteus aims to provide a portable, fast, and light operating system that you can boot directly in less than 15 seconds (in the case of LXDE desktop) from CD, USB flash drive, hard drive, or other bootable storage media.

KDE Plasma 5 August 2020 release for Slackware

Filed under
KDE
Slack

New Plasma5 packages for Slackware-current are ready for download & installation. I skipped July (holiday season) and so here is KDE-5_20.08 aka my August 2020 release. Be sure to read the upgrade instructions very carefully to prevent breakage, because starting with my June batch the goal is to remove Slackware’s ConsoleKit2 and replace it with elogind!.

It would not harm if you (re-)read my previous blog article about Plasma5, “Replacing ConsoleKit2 with elogind – first steps“. It has a lot more detail about the reasons for this move as well as guidance on using the Wayland Window Manager (as a test) instead of regular X.Org. Note that Wayland sessions still need a lot of maturing and X.Org will remain Slackware’s default choice.

[Slackware] Preparing to move to elogind

Filed under
Slack

Slackware community is very active nowadays, and that's for a reason. They are waiting for the big update coming to Slackware, which is the new Plasma 5 and XFCE. It has been requested for so long after -current start moving, but Pat hasn't made the change until 2020 when big basic components such as Qt5 went in and many followed up.

There were some distractions along the way, such as PAM taking some time to test (it was initially planned for a day or two in testing/), but at the end it was a smooth migration. I barely notice any changes since all the changes happening under the hood and it works well both in my MATE and Cinnamon project (basically for Cinnamon since i already have PAM installed, but not as part of the core packages. It just sit there as a requirement for Cinnamon-screensaver).

For next Plasma 5 and XFCE, there are some another changes needed for it to go smoothly and that's UPower and elogind. Slackware 14.2 up to -current is still using the old UPower which is already deprecated for some time, but since it's related to many other libraries/applications, Pat kept them until it's time to move on with the rest of the projects and i believe it's time. Newer UPower is needed by Plasma 5, XFCE, mate-power-manager 1.24 (it's still at 1.22 for now due to this constraints) and better battery support in Cinnamon.

Plasma5 for Slackware: KDE 5_20.05. Also, new Ardour 6.0

Filed under
KDE
Slack

A new batch of Plasma5 packages for Slackware-current is available now. The KDE-5_20.05 release is also the last monthly update you’ll see from me for a while in my ‘ktown‘ repository. I expect Pat to add Plasma5 to Slackware-current, but I am done waiting and have an urgent need to dedicate my spare time to other matters. With PAM finally added to the core distro, there should no longer be a showstopper for getting rid of KDE4 and replacing it with Plasma5.

And remember, these packages will not work on Slackware 14.2. Along with adding the May batch for -current, I have removed the old (KDE 5_17.11) Plasma5 packages that were still in my ‘ktown’ repository for Slackware 14.2. They have been un-maintained for two and a half years, who knows what security issues they cause. If you really want or need Plasma5, migrate to Slackware-current please.

  • Qt 6.0 RC and timelines for 6.1 and 6.2

    Hi all, First of all, I wanted to thank everybody for the hard work towards getting Qt 6.0 out of the door. We now have a first RC out, so we’re definitely getting very close to the 6.0.0 release. With that and the fact that we now have a 6.0 branch, it’s also time to start looking a bit ahead towards 6.1 and 6.2. We have long discussed, that the timing of our feature releases to be just before summer and Christmas vacation is a bit unfortunate, as we have little slack for delays without going into the vacation period. Especially the releases in December have sometimes been difficult in that respect. So we’d like to push the schedule a bit and move the minor releases towards a Spring/Autumn schedule. A somewhat shorter release cycle directly after 6.0 is probably a good idea anyway, as we will probably still need to do changes/fixes that don’t quite fit with our policy for patch level releases. So the idea is to shorten the release cycle for Qt 6.1 a bit and focus mainly on bug fixing and stability for that release. We’d aim for a feature freeze by the end of January, and a final Qt 6.1.0 release end of April. 6.2 would then also happen a bit earlier, with a feature freeze in June and a release end of September. Content wise, I believe we’ll start seeing more and more of the add-ons from Qt 5 being supported over the next 6-9 months, and I believe that with Qt 6.2 we will have brought most modules that we supported in Qt 5.15 over to Qt 6. Cheers, Lars

  • Qt 6.1, Qt 6.2 Expected To Come Sooner With Tightened Release Cycles - Phoronix

    Qt 6.0 is releasing in December and The Qt Company is already drafting plans for the release cycles of Qt 6.1 and Qt 6.2 LTS next year. Normally Qt is on a six-month release cadence but next year's Qt 6.1/6.2 releases will likely be tightened up both to address a long-standing gripe of the current timing that often puts new releases around summer holidays and the Thanksgiving~Christmas holiday season. To try to move off those May and November~December release windows, they are looking at tightening up the cycles for Qt 6.1 and Qt 6.2, with the latter being the first long-term support release of the Qt6 series. Lars Knoll is proposing that Qt 6.1 be shipped by the end of April which would put the feature freeze already at the end of January. But for Qt 6.1 the emphasis anyhow will likely be on bug fixing and stability improvements after all the changes in Qt 6.0, so a tightened up Qt 6.1 release makes sense.

  • Netfilter virtual workshop 2020 summary

    Once a year folks interested in Netfilter technologies gather together to discuss past, ongoing and future works. The Netfilter Workshop is an opportunity to share and discuss new ideas, the state of the project, bring people together to work & hack and to put faces to people who otherwise are just email names. This is an event that has been happening since at least 2001, so we are talking about a genuine community thing here. It was decided there would be an online format, split in 3 short meetings, once per week on Fridays. I was unable to attend the first session on 2020-11-06 due to scheduling conflict, but I made it to the sessions on 2020-11-13 and 2020-11-20. I would say the sessions were joined by about 8 to 10 people, depending on the day. This post is a summary with some notes on what happened in this edition, with no special order. Pablo did the classical review of all the changes and updates that happened in all the Netfilter project software components since last workshop. I was unable to watch this presentation, so I have nothing special to comment. However, I’ve been following the development of the project very closely, and there are several interesting things going on, some of them commented below. Florian Westphal brought to the table status on some open/pending work for mptcp option matching, systemd integration and finally interfacing from nft with cgroupv2. I was unable to participate in the talk for the first two items, so I cannot comment a lot more. On the cgroupv2 side, several options were evaluated to how to match them, identification methods, the hierarchical tree that cgroups present, etc. We will have to wait a bit more to see how the final implementation looks like. Also, Florian presented his concerns on conntrack hash collisions. There are no real-world known issues at the moment, but there is an old paper that suggests we should keep and eye on this and introduce improvements to prevent future DoS attack vectors. Florian mentioned these attacks are not practical at the moment, but who knows in a few years. He wants to explore introducing RB trees for conntrack. It will probably be a rbtree structure of hash tables in order to keep supporting parallel insertions. He was encouraged by others to go ahead and play/explore with this.

  • The Peculiar State Of CPU Security Mitigation Performance On Intel Tiger Lake - Phoronix

    One area not talked about much for Intel's latest Tiger Lake processors are hardened CPU security mitigations against the various speculative execution vulnerabilities to date. What's peculiar about Tiger Lake though is now if disabling the configurable mitigations it can actually result in worse performance than the default mitigated state. At least that's what we are seeing so far with the Core i7 1165G7 on Ubuntu 20.10 Linux is the opposite of what we have been seeing on prior generations of hardware. [...] On each of these Dell XPS notebooks were clean installs of Ubuntu 20.10 with security / stable release updates of the time and on their default Linux 5.8 kernel. The out-of-the-box / default mitigation performance was tested on each notebook followed by re-testing the same laptop and software stack after booting with mitigations=off. Here is the geometric mean of all the results before digging into the individual data points, but as you can see mitigations=off was of noticeably help to the older Kaby Lake R and Whiskey Lake processors, previous-generation Ice Lake was of some help but less given more hardware mitigations, and now with Tiger Lake the tables have turned where disabling the mitigations actually hurt the performance.
