I recently blogged about some problems with UI tests in GNOME due to xdg-desktop-portal-gnome. Unfortunately, I also started to experience problems similar to those with KDE Plasma 6.1 (Linux EndeavourOS and Arch); as in the other blog post, the problem is only with Wayland. I’ll use this example project (taken from my TDD book): https://github.com/LorenzoBettini/demo-attsw. It is […]
Before KDE Plasma 6.1 (released a few days ago and already available in Arch), if you wanted to configure a “modifer-only” shortcut (e.g., SUPER key, also known as META, to activate the “Overview” effect), you had to manually modify the “~/.config/kwinrc” file and add these lines:
|
1 2 |
[ModifierOnlyShortcuts] Meta=org.kde.kglobalaccel,/component/kwin,org.kde.kglobalaccel.Component,invokeShortcut,Overview |
Another example is if you wanted the SUPER […]
I typically have several EndeavourOS installations on my computers: one for KDE, one for Hyprland, etc. Thus, I want to have different UEFI entries, but they would all have “endeavouros”, with each one overriding the others. You can change the grub ID later by issuing a proper “grub-install” program from the running system or by […]
I have already blogged about KDE applications in Hyprland. However, with the latest updates, things broke a bit especially with Dolphin, which does not recognize file associations anymore: double-clicking on a file always shows this empty menu, as if it could not find any associations for any file: On the Arch forum that has already […]
I haven’t used Fedora for a few years but wanted to try it again (Fedora 39). I was immediately hit by a problem, which is not due to Fedora itself, I seem to understand. I’ll use this example project (taken from my TDD book): https://github.com/LorenzoBettini/demo-attsw. It is a simple Java Swing application where UI tests […]
As I have written, I’m using “Oh-My-Zsh” with Nerd icons and fonts. It has always worked perfectly in KDE. A few days ago, KDE Plasma 6 landed in Arch (and thus, EndeavourOS), and after upgrading, the Nerd fonts were not displayed in Konsole and Kate (and, I guess, in other KDE applications). For example, before […]
At last, KDE Plasma 6 has landed in Arch Linux (and in EndeavourOS, of course), and you’re eager to try the return of the desktop effect “Desktop Cube”! 🙂 You try to enable that in the System Settings “Desktop Effects.” You try the default shortcut “Meta + C”, and… it doesn’t work 🙁 Oh, they […]
This is a quick post about having nice fonts in Eclipse in Windows 11, based on my experience (maybe I had bad luck with the default configurations of Eclipse and/or Windows). When I bought my Acer Aspire Vero, I found Windows 11 installed, and now and then, I’m using Windows 11 (though I’m using Linux […]
In this blog post, I will describe a few scenarios where you want to update versions in a multi-module Maven project consistently. In these examples, you have both a parent POM, which is meant to contain common properties and configurations to be inherited throughout the other projects, and aggregator POMs, which are meant to be […]
I had already blogged on how to limit battery charge on LG Gram in Linux. In that post, you had to manually set the threshold “80” in the file “/sys/devices/platform/lg-laptop/battery_care_limit”. With TLP, the procedure is easier and more automatic. First, you must install tlp (remember that tlp conflicts with power-profiles-daemon, so you have to disable […]
I’ve just started experimenting with the Wayland compositor Hyprland and wanted to use my favorite wallpaper manager, Variety. Unfortunately, Variety does not support Hyprland out of the box. However, it’s easy to make it work also on Wayland. I’m going to use Arch Linux in this blog post. First of all, you must install “swaybg”, […]
I finally took the time to try exa, “a modern replacement for ls”. This is a brief article for installing exa in Arch Linux with an additional package for the icon fonts (in a few installations, boxes were shown instead of icons, that’s why I’m writing this blog article, hoping to save you some time). […]
UI tests are delicate since when you run them, you must not interact with the computer, or you will disturb the tests, which will likely fail. In Linux, you can use Xvfb, but windows will not have a title, which might break UI tests that rely on that. For example, Eclipse SWTBot tests work best […]
While working on my TDD book, I played with Maven profiles to write the chapter. If you use Maven profiles, you might want to use an activation strategy to enable the profile under certain circumstances automatically. There’s also a particular option, “<activeByDefault>”, which seems self-explanatory. This must mean that that profile will be constantly active […]
Quoting from https://community.kde.org/Baloo, Baloo is the file indexing and file search framework for KDE Plasma, with a focus on providing a very small memory footprint along with extremely fast searching. Unfortunately, it has a bad reputation for being a resource hog. However, it all boils down to configuring it appropriately (of course, according to your […]
In this post, I’ll describe a few problems with Docker in Fedora and how to fix them. In particular, I’ll try to provide an analysis of the problems and the sources of the solutions. I’ve experienced a few problems with Docker in Fedora (35 and 36). I first installed docker-ce by following the official documentation: […]
I have no problem installing VirtualBox and the related tools and extensions in Ubuntu and Arch. In Fedora, things are a little bit harder. First, I think it’s better NOT to download binaries distributed by VirtualBox: I’m using Fedora packages that are available from RPM Fusion Free. Thus, first of all, you have to enable […]
TL;DR If you want to access your Google Calendars from Korganizer or Kalendar, remember to enable “Enable the KDE wallet subsystem”. I had already written about the cumbersome procedure to access Google accounts in KDE, and I thought I had learned enough to “easily” set my Google calendars in KDE. I was wrong. Today I […]
I use VirtualBox a lot for testing purposes, mainly to experiment with a Linux distribution (to see whether it’s worthwhile to install it on bare metal) and to test procedures that might involve some complex (and maybe “dangerous”) operations. After you install VirtualBox Guest Additions, things like bidirectional copy-and-paste will work. Some distributions seem to […]
Recently, I started to contribute and maintain Pitclipse, an Eclipse plugin for running mutation testing with PIT. We needed a mechanism to detect whether JUnit 5 is in the classpath of a Java project (so that we could run PIT with its JUnit 5 plugin). The first implementation of such a mechanism was rather cumbersome […]
