Filed under

Users of Kubuntu 17.10 Artful Aardvark can now upgrade via our backports PPA to the 3rd bugfix release (5.12.3) of the Plasma 5.12 LTS release series from KDE.

(Testers of 18.04 Bionic Beaver will need to be patient as the Ubuntu archive is currently in Beta 1 candidate freeze for our packages, and but we hope to update the packages there once the Beta 1 is released)

The full changelog of fixes for 5.12.3 can be found here.

    KaOS is proud to announce the availability of the March release of a new stable ISO.

  • KaOS Linux Switches to Falkon Browser, March's Release Adds KDE Plasma 5.12 LTS

    The developers of the KaOS Linux operating system announced today that availability of March 2018's ISO snapshot with up-to-date components and latest GNU/Linux technologies.

    KaOS 2018.03 is now available for download and it's the first to ship with the recently released KDE Plasma 5.12 LTS desktop environment by default. In fact, the new release includes KDE Plasma 5.12.2 LTS, along with the KDE Applications 17.12.2 and KDE Frameworks 5.43.0 software suites built on Qt 5.10.1.

  • Screen sharing in Plasma wayland session

    One of the important missing features in Plasma wayland session is without a doubt possibility to share your screen or record you screen. To support this you need help of the compositor and somehow deliver all needed information to the client (application), in ideal way something what can be used by all DEs, such as Gnome. Luckily, this has been one of the primary goals of Pipewire, together with support for Flatpak. If you haven’t heard about Pipewire, it’s a new project that wants to improve audio and video handling in Linux, supporting all the usecases handled by PulseAudio and providing same level of handling for video input and output. With Pipewire supporting this, there was recently a new API added to xdg-desktop-portal for screen cast support and also for remote desktop. Using this API, applications can now have access to your screen content on Wayland sessions or in case they are running in sandbox. With various backend implementation, like xdg-desktop-portal-kde or xdg-desktop-portal-gtk, they just need to support one API to target all desktops. Screen cast portal works the way, that the client first needs to create a session between him and xdp (xdg-desktop-portal) backend implementation, user then gets a dialog with a screen he would like to share and starts screen sharing. Once he does that, xdp backend implementation creates a Pipewire stream, sends back response to the client with stream id and then client can connect to that stream and get its content. Once he no longer requests content of the selected stream, xdp backend implementation gets information that nobody is longer connected to the created Pipewire stream and can stop sharing screen information and xdp backend implementation is again ready to accept next requests for screen sharing. This is all happening in the background so there is really no cool picture I can show, at least this dialog which you get when you request to share a screen.

  • KDE Plasma Working On Wayland Screen-Sharing With XDG-Desktop-Portal / Pipewire

    With Wayland not enforcing any standard for screensharing, KDE developers are now building off GNOME's approach of XDG-Desktop-Portal and PipeWire for desktop/screen sharing for adding this feature to Plasma on Wayland.

    Red Hat / KDE developer Jan Grulich has been working on screen sharing support for the KDE Plasma Wayland session. For this understandably he's gone with the groundwork laid by XDG-Desktop-Portal/Pipewire to allow for a quick bring-up of this support.

  • KDevelop with Cppcheck Integration

    Starting with 5.1 release KDevelop supports built-in integration with static-analysis tool Cppcheck. Cppcheck provides unique code analysis to detect bugs and focuses on detecting undefined behaviour and dangerous coding constructs. The goal is to detect only real errors in the code (i.e. have very few false positives). Such analysis is very useful for all projects, especially for projects with complex structure and large code volume. Convenient integration with the development environment greatly simplifies and speeds up the process of code checking, as there is no need to study the analyzer documentation, its manual configuration and code navigation when processing the analysis results.

  • First 5 Things to Do After Booting Your KDE Slimbook II

    You unboxed your KDE Slimbook II, posted the pics to Instagram, and logged into the desktop. What you are seeing now is Plasma, a graphical environment created by a worldwide network of top-class programmers. Plasma may look familiar, but it is not Windows or macOS; it’s something much better. It is Free Software for starters — no hidden costs, bloatware and spyware here. Secondly, it is made to be tweaked, letting you adapt it to your precise needs.

  • Plasma secrets: digital clock

    Pretty simple and straightforward, but then some people might struggle figuring out how to change the clock. The most obvious approach is to tweak the existing one, and indeed, a popular question could be: how to change the vertical height of the clock? But that's a hardcoded widget feature, and you can't do that easily. So you need a new widget - or use Plasma 5.12.1, which you can find in KDE neon. Lots of sweet reading right there.

    I believe Event Calendar, additional features notwithstanding, does a pretty good job, and it gives the system an ever so slightly more professional look. Once you're neck deep in tweaks and loving it, then it becomes an important part of the overall equation. Art can be like that. A blessing and a curse. I hope you like this little guide. More Plasma secrets coming your way soon.

  • This week in Discover, part 8

    This was a week of polish and preparation for Discover. We’ve got some nice new features in the pipeline but we’re not quite ready to announce them just yet. One is implemented but needs more polish, and another is under construction. I think you’ll like ’em once they’re ready!

  • Tips and Tricks for KDE 5 Dolphin File Manager

    Years ago when the KDE team decided to move from Konquerer to Dolphin in KDE4, it was controversial, with some people in support of the move, and others against it.

    Now, it’s widely recognized that Dolphin is probably the most powerful file manager for GNU/Linux, with a number of features and enhancements to make workflow as simple, quick, and informative as possible.

    With that said, I thought I would perhaps share just a few things that people may overlook in their Dolphin setup, that you might enjoy.

  • Connecting new screens

    This week, Dan Vratil and me have merged a new feature in KScreen, Plasma’s screen configuration tool. Up until now, when plugging in a new display (a monitor, beamer or TV, for example), Plasma would automatically extend the desktop area to include this screen. In many cases, this is expected behavior, but it’s not necessarily clear to the user what just happened. Perhaps the user would rather want the new screen on the other side of the current, clone the existing screen, switch over to it or perhaps not use it at all at this point.

  • KDE Plasma 5.13 Getting Friendlier Monitor Hot-Plug Handling

    KDE's KScreen screen configuration tool is getting some nice improvements as part of the Plasma 5.13 development cycle.

    KDE developers Sebastian Kügler and Dan Vratil have been working to improve the behavior of the KDE Plasma desktop during monitor hot-plugging events. Current behavior is that the KDE desktop would be extended to include the new screen as soon as it's attached. With the new KScreen to be part of Plasma 5.13, there is a screen layout selection dialog that will appear on the primary display output when a new monitor/display is attached.

  • Animated Plasma Wallpaper: Asciiquarium

    Years ago, for KDE 3, I had ported a console “asciiquarium” to operate as a KDE screensaver, called “KDE asciiquarium“. By KDE 4.2, it was included as part of the kdeartwork module by default.

    Since the KDE 3 times when I started this screensaver, our desktop concept has changed around a bit. We’ve developed the Plasma desktop, and have effectively deprecated the idea of screensavers (which are increasingly less popular), though lock screens are still important.

  • KDE Plasma 5 Should Soon Finally Be Ready For FreeBSD Ports

    Adriaan de Groot continues working on improving the KDE stack for FreeBSD. The moment is finally near where KDE Plasma 5 along with the modern KDE Applications stack should soon be available via the FreeBSD Ports collection.

    In preparation for finally having the modern KDE desktop stack available via FreeBSD Ports, the older KDE4 ports have been moved aside (but are still accessible via x11/kde4). KDE4 will continue to work for those who have already installed it on FreeBSD, but they are reorganizing these packages in preparation for pushing out the modern KDE Plasma 5 + Apps stack.

First Version of Falkon Web Browser Released

Filed under

The first release of Falkon, the KDE web browser formerly known as QupZilla, is available to download.

Falkon 3.0.0 is the first formal release of the rebadged Qt-based web navigator, and follows a name change in summer of last year.

As this is more of a rebranding than a brand new app you won’t notice too many visual differences between the latest stable release of QupZilla 2.2.5, and the first hatching of Falkon 3.0.

KDE: FreeBSD, Benchmarks and More

  • Outta the way, KDE4

    KDE4 has been rudely moved aside on FreeBSD. It still installs (use x11/kde4) and should update without a problem, but this is another step towards adding modern KDE (Plasma 5 and Applications) to the official FreeBSD Ports tree.

    This has taken a long time mostly for administrative reasons, getting all the bits lined up so that people sticking with KDE4 (which, right now, would be everyone using KDE from official ports and packages on FreeBSD) don’t end up with a broken desktop. We don’t want that. But now that everything Qt4 and kdelibs4-based has been moved aside by suffixing it with -kde4, we have the unsuffixed names free to indicate the latest-and-greatest from upstream.

  • On Benchmarks

    A well knwon Linux website published a “benchmark” about Plasma Wayland vs Plasma Xorg vs Gnome Shell (Wayland and Xorg). Before anybody tries to draw any conclusion: this is not a proper benchmark. It shows no statistical relevance as it was only tested on one hardware and only on one distribution. It shows numbers, that’s it. The numbers might be nice or not, I don’t know. I am not able to draw any conclusions from these numbers.

  • Event Notes

    But if you’re thirsting for more KDE events, there’s the list of KDE Sprints which is where you will find the small, focused, fairly short events for hacking on a well-defined project. Some are open for visitors, and if there’s something you want to hack on with a group of KDE contributors, get organising! (Like, seriously, getting a hacking weekend together is just a few phone calls to reserve a rental house somewhere nice and to arrange for transportation — if you can get the people together, which is usually the biggest problem).

IU not UI – Want a great desktop? Use the brain.

Filed under

The desktop works. It’s a given. Plasma works, too. No argument there. But that does mean we’ve peaked, or even come remotely close to nailing the desktop formula. It is true that a lot of things we do today have become a habit, which is why people rarely look at the norms and wonder if they might be silly or inefficient. They just are. But Plasma is a growing, evolving, and it has the power – and chance – to break through the stagnation. It won’t be trivial or fast. But it’s possible.

The main reason why Plasma can do this – it has the most advanced desktop ecosystem in the Linux world, and it’s probing into the waters of mobile usage. It could become the superior, superlative face of the desktop, so that one day, when the technology and human needs finally meet, i.e. the Linux desktop will have the applications that the majority of people need, it will not fail due to a classic mistake of neglecting the convoluted randomness of computer usage. Linux never had to face this problem due to its small share. But that day may yet come. You don’t want to be the guy telling your grandma to chroot her mail, now do you?

New Terminal App in Chome OS Hints at Upcoming Support for Linux Applications

According to a Reddit thread, a Chromebook user recently spotted a new Terminal app added to the app drawer when running on the latest Chrome OS Dev channel. Clicking the icon would apparently prompt the user to install the Terminal app, which requires about 200 MB of disk space. The installation prompt notes the fact that the Terminal app can be used to develop on your Chromebook. It also suggests that users will be able to run native apps and command-line tools seamlessly and securely. Considering the fact that Chrome OS is powered by the Linux kernel, this can only mean one thing. Read more
