KDE Plasma 6.7 Delivers Per-Screen Virtual Desktops and CSS Theming
The latest release introduces the Union styling engine, per-screen virtual desktops, and critical workflow refinements for power users.
Linux desktop environments often force a compromise between rigid stability and hyper-configurable chaos. KDE has historically leaned toward the latter, offering unparalleled customization at the cost of occasional fragmentation across its vast ecosystem. The release of KDE Plasma 6.7 strikes a deliberate balance, delivering long-requested architectural features alongside a major attempt to clean up its notoriously complex theming pipeline.
Dedicated to the memory of long-time KDE supporter Eric Laffoon, who passed away in May 2026, this release brings highly anticipated features to fruition while laying the groundwork for modern, web-standard desktop styling.
Per-Screen Virtual Desktops Arrive
For developers and power users juggling multi-monitor setups, the lack of independent workspaces has been a persistent pain point. After 21 years of development and user requests, Plasma 6.7 finally introduces per-screen virtual desktops.
Previously, switching a virtual desktop on one monitor would force a workspace switch across all connected displays, disrupting developers who prefer to keep reference documentation or terminal outputs static on a secondary screen. Users can now isolate workspace switching to a single display. This is paired with usability tweaks in the Overview screen (triggered via Meta + W), where users can now cycle through virtual desktops using a mouse scroll wheel or the Page Up and Page Down keys.
Union: Consolidating the Theming Fragment
Theming in KDE has historically been a fragmented affair, split across Plasma styles, QtQuick, and QtWidgets. To address this, Plasma 6.7 introduces "Union," a new unified theming system currently available as a technology preview.
Union aims to streamline the styling process by allowing developers and designers to style the entire desktop environment and its applications using standard CSS. By leveraging the web's most common styling standard, KDE lowers the barrier to entry for developers who want to customize their environments without diving into complex QML or C++ styling APIs.
In this inaugural release, Union provides a tech preview of the QtQuick style. It is disabled by default, but users can test it by installing the union package and selecting it under System Settings > Colors & Themes > Application Style. Applications must be restarted to apply the style, which is designed to look nearly identical to the default Breeze theme during this preview phase.
Sandbox Visibility and Background Apps
Modern Linux desktop deployments increasingly rely on containerized packaging formats like Flatpak. However, monitoring sandboxed background processes has historically been difficult due to the isolated nature of these runtimes.
Plasma 6.7 addresses this by extending its System Tray to support the newer "Background Apps" portal. This ensures that sandboxed applications running in the background are visible to the user, matching the monitoring capabilities previously reserved for traditional background processes.
Additionally, the desktop's printing stack has received significant updates. The System Tray printer icon now features a badge indicating the number of active print jobs. For enterprise environments, Plasma 6.7 simplifies connections to shared printers on Windows networks and introduces a redesigned print queue management tool to handle multiple active devices.
Power-User Ergonomics and Graphics
Several minor but impactful workflow enhancements target developer productivity:
- Type-Ahead Desktop Navigation: The desktop layout now supports a "type-ahead" mode, allowing users to quickly select files by typing directly on the desktop. This behavior can be toggled back to launching KRunner via the desktop settings menu.
- Time Zone Comparisons: The Digital Clock widget now displays the exact hour difference between configured time zones and the local system time, eliminating the mental math of coordinating with remote engineering teams.
- Simultaneous HDR and ICC Profiles: On the graphics front, users no longer have to choose between color management using an ICC profile and enjoying HDR content; Plasma 6.7 supports both concurrently.
- AMD Laptop Low-Brightness Controls: Users can now control whether screen colors shift toward redder spectrums at extremely low brightness levels on compatible AMD laptops.
Finally, as the project prepares for KDE's 30th anniversary, Plasma 6.7 revives the classic Oxygen theme and its light counterpart, Air, bringing them up to feature parity with the default Breeze theme, complete with support for adaptive opacity and modern panel positioning.

i'm excited to see kde embracing modern styling, but i still wish their api docs were more thoroughly typed - all that complexity is a maintenance nightmare without proper type safety
