I wrote a post about updating KDE Neon without entering your password before. Since then the authentication system has changed a bit and a different approach is necessary. This post will explain what to do on Kubuntu 23.10 – however it should work on other distros using PackageKit (and recent Polkit).

Kubuntu: module “org.kde.desktop” is not installed
Recently this error showed up on my Kubuntu 23.10 while trying to run applications using QtQuick, such as QtDesignStudio or just a new QML project with QtCreator. The application either outright does not run or has serious GUI issues.
Turns out this is probably an issue related to software and distributions switching from Qt5 to Qt6.
Continue readingSimple Lua console in Qt
Lua is a simple, fast and embeddable scripting language. Capability to run Lua scripts can be relatively easily added into C and C++ applications. Due to it’s ease of use and performance it’s being used in computer games (Crysis, Garry’s mod, …), general software (Wireshark, Neovim, …) and also embedded devices (Logic Machine). Let’s take a look how to create a very simple Lua console GUI with Qt.

Despite its hardware being somewhat dated in 2024, the first generation of LattePanda can still find its use. It’s a cheap, fanless x86 single board computer that can just be good enough for your use case.
Continue readingManaging packages on KDE Neon without entering a password
KDE Neon is build on Ubuntu LTS (currently 18.04) with up-to-date Qt and KDE libraries. Updates tend to arrive pretty much every other day and it gets annoying to enter your password every time you launch Discover to install an update.

Note: This post was first published on the Mevisys website.
When we talk about environment monitoring, temperature monitoring is one of the most ubiquitous use-cases and makes for an illustrative example as well. The measurement side of the process is not an area that would offer many exciting innovations in this day and age – today it is all about how you process the collected data.

I have recently gotten involved in setting up both latest Gnome (Ubuntu) and KDE (Manjaro) environment on two X230 Thinkpads with fingerprint sensors and the question of how to make them work appeared.
ThinkPad battery charge thresholds
If you want to take good care of your lithium-based battery, you should not charge or discharge it completely, but stick just to a part of the total range. This way you can increase the number of charge-discharge cycles it survives and thus prolong it’s life.
Certain laptops offer ways to set battery charging thresholds.
Terminal window resizing in xfce
Have you ever been annoyed by terminal windows not aligning their edges with edges of other windows or screen edges in xfce? Seems like there is an easy fix, if you know where to look!
The long and painful road to useful Plasma 5 desktop
UPDATE 22.1.2018
Some parts of this angry rant still hold true, but Plasma desktop sure improved greatly since this post was originally written. I now run latest KDE software on Manjaro for several months and it sure got good enough for my day-to-day use. New post incoming… maybe when I get around to it.

First of all, I would like to state that I’m a fan of KDE. Some of their programs and utilities are unmatched by any other. For example file browser Dolphin, text editor Kate, the great PIM suite Kontact, … the list goes on. Also the level of customization is borderline fetishist. KDE desktop lets you do absolutely anything you ever thought possible and more… or it seems so at first. Then, in the moment of awe, the first crash comes. Then you start noticing weirg glitches and somehow missing features.
