The KDE community will again participate in the Open Source Promotion Plan (OSPP), a program in which students can contribute to open source projects. Burgess Chang, is the KDE community contact.

As part of OSPP 2024, Hànyáng Zhāng (张汉阳) added Android support to Blinken. The work done is described in a series of blog posts, available in both English and Mandarin. The Android version is available from the KDE F-Droid nightly repository.

Unlike the Google Summer of Code, where stipends are funded by a company, stipends are primarily funded by the Chinese government with options for open source communities to contribute additional stipends if they wish to have more students participate in their projects than they get allocated. It is good that there is recognition that contributing to open source software is a skill that students should acquire.

The range of contributions that can be made in OSPP is not just limited to programming, contributions to other aspects that improve the open source software ecosystem such as translation and documentation are welcome. As it is a government funded program, there is a little more oversight to ensure tax payer funds are well spent. In particular, for most projects, contributions should be made to a publicly available repository associated with the project and that student participants are selected primarily based on their project application.

The plan aims to increase the programming and software engineering skills of students by encouraging them to participate in real world projects during their vacation period. While it is funded by the Chinese people, open source projects with contributors from all over the world apply to participate, and students from any part of the world can also apply to participate.

Mandarin and English are the official communication languages for the program, knowledge of one of these is sufficient to participate in the program.

The OSPP website lists the dates for each phase of the program. Important dates for this year are:

• 04 April - 04 May: Project submission period for approved open source communities
• 09 May - 09 June: Student project application period
• 01 July - 30 September: Coding and development period for accepted projects

Become an Artist on a Budget

Plasma's login experience is an area that we know requires some improvement — it works OK in the basic case, but it's very barebones and doesn't handle anything beyond that.

As a complete desktop experience, it's our job to provide support for the edge cases too.

What we want

• Great out-of-box experience in multi-monitor and high DPI and HDR
• Keyboard layout switching
• Virtual keyboards
• Easy Chinese/Japanese/Korean/Vietnamese (CJK) input
• Display and keyboard brightness control
• Full power management
• Screen readers for blind people (which then means volume control)
• Pairing trusted bluetooth devices
• Login to known Wi-Fi for remote LDAP
• Remote (VNC/RDP) support from startup

A brief history

In Plasma 5, we retired our own bespoke display manager KDM, in favour of SDDM. A display manager started for multiple lightweight Qt Desktops. It was modern at the time making use of new QML for the front and as a big selling point at a time when Plasma was also making use of it.

SDDM's Big Architecture Problem

We ran into a problem, though. SDDM is designed to show a single greeter window, loading arbitrary QML from the specified theme.

Whilst this all sounded great for Plasma, the abstraction is at the wrong level — for our wishlist we need a lot more tight integration from our login screen than just a window showing sessions and users.

With SDDM, power management is reinvented from scratch with bespoke configuration. We can't integrate with Plasma's network management, power management, volume controls, or brightness controls without reinventing them in the desktop-agnostic backend.

SDDM was already having to duplicate too much functionality we have in KDE, which was very frustrating when we're left maintaining it.

The Competition

GNOME's GDM is the gold-standard of display managers, and it achieves this higher level of quality by running half of a Gnome session.

SDDM got closer when it added Wayland support — it had to use a compositor such as KWin. But because the project tries to be agnostic between desktops, it has to support any compositor. There aren't compositor-agnostic ways to do even simple things like set the keyboard layout, so in the end this compositor agnosticism goal simply didn't work.

Theme Problems

A major mistake we made throughout Plasma 5 was conflating "writing UI in a high level scripting language" with "it's themable" as the same thing — they are not. QML does make it easy to modify and iterate without programming skills, but it still contains business logic. It should not be the primary method of customisation that we expose to users.

Ultimately, this was poor for end users. We pushed back on adding support for configurable theme options, because building a theme engine within a theme was wasteful! But often people want to just change a few things. Choosing a theme meant finding a combination that had everything. The store filled up with themes that are 99.9% identical code-wise; most are just wallpaper mods.

It was also poor for theme developers. Not only do they have to modify the visuals, but also re-implement focus handling, accessibility, and the same boring logic again. They can't benefit from widespread testing so regressing these functionalities is common. Reddit is full of screenshots of broken SDDM themes.

Finally, it's poor for us Plasma developers: theme support holds us back from adding new features or tidying code; if we want to add a new feature that in any way affects existing UIs, the situation get very messy very fast. The end result is that features just don't land, and the end user is the one that misses out.

So, what's the plan?

It's worth stressing nothing is official or set in stone yet, whilst it has come up in previous Plasma online meetings and in the 2023 Akademy. I'm posting this whilst starting a more official discussion on the plasma-devel mailing list.

Oliver Beard and I have made a new mutli-process greeter, that uses the same startup mechanism as the desktop session. It doesn't have all the features that we propose at the start of the blog, but an architecture where features and services can be slowly and safely added.

For customisation we intend to expose the same familiar settings that exist in Plasma and bring the design more in-line with the existing screenlocker where we also dropped arbitrary QML years ago. We'll make the wallpaper configurable with any existing wallpaper plugins, and expose the existing plasma theme and colour settings. Syncing will be a case of copying files, not re-inventing things.

The backend

When starting work on this, I tried to explore all alternative backends out there even with fully working implementations, however in practice nothing was maintained that matched our requirements. SDDM has been proven in the real world, so we have taken that and stripped it down to cover what we want moving forwards. I also aim to incubate it into the KDE ecosystem to have full autonomy over the project and merging stuck patches.

Current State

All of this has been implemented as two new repositories. Plasma Login Manager a continuation of SDDM and Plasma Login for front end and KCM (settings) code. These might be merged at some point.

The new code all works, and is at roughly feature parity with what we're replacing. A screenshot looks roughly the same as a stock Plasma SDDM setup. Whilst this is at a state where developers can opt-in, I would not want distros to be packaging things at this point.

Please do reach out if this sounds interesting, either directly or in the Plasma Matrix room - or with merge requests!

KdeGuiTest (previously called KdeEcoTest) is an automation and testing tool which allows one to record and simulate user interactions with the GUI of an application. It is being developed as part of the KDE Eco initiative to create usage scenario scripts for measuring the energy consumption of software. The main goals in Season of KDE 2025 are (i) to debug remaining issues, and (ii) to make KdeGuiTest more user-friendly by creating a Graphical User Interface so it is easier to create, edit, and run emulation scripts.

Progress of the KDE season so far:

• Creation of a 4-cross PDF to be used for testing shift coordination.
• Detection of the issues affecting shift coordination.
• Fixed “Platform supported” error due to pynput.
• Integration of KdeGuiTest with its own newly-built Graphical User Interface.

SHIFT COORDINATION ERROR

There is a difference between what is recorded when creating a script and what is played when running the script.

How I planned to fix this:

• Identify the root of the shift error by creating a script to click on four target crosses, and then running the script to locate and solve differences.
• Develop and implement a correction mechanism to accurately map recorded coordinates to playback positions.

My progress so far on the shift error:

1. Creation of the 4-crosses PDF to test shift error: A target PDF is created with 4 crosses horizontally and vertically opposite each other.

2. Created a test script on the target PDF to detect shift error: I created a test script that clicks on the four crosses. I tested the KdeGuiTest tool on the target PDF and identified the issues affecting the shift error, namely:

   • Difference in mouse coordinates when scripts are created and playback
   • Screen position
   • Screen resolution

I am still working on a fix for this. See my comments at the end of this post for more.

FIXED “PLATFORM NOT SUPPORTED” ERROR DUE TO PYNPUT

While creating a script with KdeGuiTest we encountered the error “Platform not supported”. It was not recognizing the pynput backend in the code, which is the main technology used in KdeGuiTest to simulate user interactions in software applications. pynput is a Python library that allows you to control and monitor input devices. It is used for interacting with your keyboard and mouse through Python code. Read more from Mohamed Ibrahim in SoK23 here, Athul Raj K in SoK24 here, and Amartya Chakraborty in SoK24 here.

The error was fixed by installing the pynput package from https://github.com/krathul/pynput and other packages like Rust.

GRAPHICAL USER INTERFACE FOR KDEGUITEST USING PyQt5

One of the main goals in Season of KDE 2025 is to make KdeGuiTest more user-friendly and have it be easier to create, edit, and run final scripts using a Graphical User Interface.

To better understand the idea of the interface Emmanuel had in mind, I presented a prototype in one of our weekly meetings. Fortunately, it fit the proposed idea! To implement the prototype, I built the GUI from scratch with some feedback from my mentor Emmanuel. PyQt5 is used for creating graphical user interfaces with Python. It's a powerful and versatile toolkit that allows developers to build desktop applications that look and feel native on various operating systems, including Windows, macOS, and GNU/Linux.

The GUI has the following features:

• Create script interface
• Buttons for the following commands:
  • dw - define window
  • ac - add clicks
  • sc - stop add clicks
  • ws - write to the screen
  • wtl - write test timestamp to log
  • wmtl - write message to log
• Action buffer widget
• Final script widget
• A run script interface
• File dialog

You can see the current version of the scripting interface below.

LOOKING TO THE FUTURE OF KDEGUITEST

First, fixing the shift error: The main shift error identified is due to differences in mouse coordinates. The mouse coordinates are recorded in the GUI in order to track them. I will then develop and implement a correction mechanism to accurately map recorded coordinates to playback positions. Second (time-permitting), developing three test scripts in collaboration with KEcoLab to compare energy consumption of PDF readers:

1. GNU/Linux + Okular Script:

• Open PDF document
• Simulate typical reading patterns (scrolling, page turns)
• Test PDF search functionality
• Change to different view modes (single page, continuous)
• Measure annotation and highlighting features
• Document energy consumption metrics

2. Windows + Okular script:

• Replicate testing scenarios from GNU/Linux + Okular script
• Adapt window management code for Windows environment
• Collect equivalent energy consumption data points

3. Windows + Adobe Acrobat Script:

• Mirror the same testing scenarios as Okular script for a direct comparison
• Account for Adobe Acrobat's specific UI elements and behaviors
• Test comparable features (navigation, search, annotations)
• Measure energy consumption patterns

Stability improvements in KDE PIM-land, and polls in NeoChat

Welcome to a new issue of "This Week in KDE Apps"! Every week we cover as much as possible of what's happening in the world of KDE apps.

We had a busy week in PIM land with various stability improvements. We also did a small mini sprint on Saturday in Carl's kitchen where we worked and discussed about online accounts, KDE PIM, Itinerary, and Transitous, among others.

Due to a personal vacation, during which I will enjoy a three-week break from computers, this is my last "This Week in KDE Apps" blog post until April 20.
