KDE Plasma 5 is the fifth generation of the KDE Plasma graphical workspaces environment, created by KDE primarily for Linux systems. KDE Plasma 5 is the successor of KDE Plasma 4 and was first released on 15 July 2014. [1] [5] [6] It was succeeded by KDE Plasma 6 on 28 February 2024. [7]
Plasma 5 includes a new default theme, "Breeze", and increased convergence across different devices. The graphical interface was fully migrated to QML, which uses OpenGL for hardware acceleration, providing better performance and reduced power consumption. [1] [5]
Plasma Mobile is a Plasma 5 variant for Linux-based smartphones.
KDE Plasma 5 is built using Qt 5 and KDE Frameworks 5. [8] [9] It improves support for HiDPI displays and ships a convergent graphical shell, which can adjust itself according to the device in use. 5.0 also includes a new default theme, dubbed Breeze. Qt 5's QtQuick 2 uses a hardware-accelerated OpenGL(ES) scene graph (canvas) to compose and render graphics on the screen, which allows for the offloading of computationally expensive graphics rendering tasks onto the GPU, freeing up resources on the system's main CPU. [1]
KDE Plasma 5 uses the X Window System and Wayland. Support for Wayland was prepared in the compositor and planned for a later release. [1] It was made initially available in the 5.4 release. [10] Stable support for a basic Wayland session was provided in the 5.5 release (December 2015). [11]
Support for NVIDIA proprietary driver for Plasma on Wayland was added in the 5.16 release (June 2019). [12]
Since the split of the KDE Software Compilation into KDE Plasma, KDE Frameworks and KDE Applications, each subproject can develop at its own pace. [13] KDE Plasma 5 is on its own release schedule, with feature releases every four months, and bugfix releases in the intervening months.
The latest Plasma 5 features the following workspaces:
ksmserver
(X Session Manager implementation) which keeps track of apps that can be run or shutdown along with given activity via subSessions functionality that keep track of state of applications (not all applications support this feature as they do not implement XSMP protocol). [17] The first Technology Preview of Plasma 5 (at that time called Plasma 2) was released on 13 December 2013. [18] On 15 July 2014, the first release version – Plasma 5.0 – was released. [1] In spring 2015, Plasma 5 replaced Plasma 4 in many popular distributions, such as Fedora 22, [19] Kubuntu 15.04, [20] and openSUSE Tumbleweed. [21]
Feature releases are released every four months (up to 5.8 every three months) and bugfix releases in the intervening months. [13] Following version 5.8 LTS KDE plans to support each new LTS version for 18 months with bug fixes, while new regular releases will see feature improvements. [22]

KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that enable collaborative work on its projects. Its products include the Plasma Desktop, KDE Frameworks, and a range of applications such as Kate, digiKam, and Krita. Some KDE applications are cross-platform and can run on Unix and Unix-like operating systems, Microsoft Windows, and Android.
Qt is a cross-platform application development framework for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed.
KWin is a window manager for the X Window System and a Wayland compositor. It is released as a part of KDE Plasma, for which it is the default window manager. KWin can also be used on its own or with other desktop environments.
Kubuntu is an official flavor of the Ubuntu operating system that uses the KDE Plasma Desktop instead of the GNOME desktop environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Kubuntu shares the same repositories as Ubuntu and is released regularly on the same schedule as Ubuntu.
openSUSE is a free and open-source Linux distribution developed by the openSUSE project. It is offered in two main variations: Tumbleweed, an upstream rolling release distribution, and Leap, a stable release distribution which is sourced from SUSE Linux Enterprise.
Compiz is a compositing window manager for the X Window System, using 3D graphics hardware to create fast compositing desktop effects for window management. Effects, such as a minimization animation or a cube workspace, are implemented as loadable plugins. Because it conforms to the ICCCM conventions, Compiz can be used as a substitute for the default Mutter or Metacity, when using GNOME Panel, or KWin in KDE Plasma Workspaces. Internally Compiz uses the OpenGL library as the interface to the graphics hardware.
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
LXDE was a free desktop environment with comparatively low resource requirements. This makes it especially suitable for use on older or resource-constrained personal computers such as netbooks or system on a chip computers.
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a Wayland compositor, because it additionally performs the task of a compositing window manager.
Lubuntu is a lightweight Linux distribution based on Ubuntu that uses the LXQt desktop environment in place of GNOME. Lubuntu was originally touted as being "lighter, less resource hungry and more energy-efficient", but now aims to be "a functional yet modular distribution focused on getting out of the way and letting users use their computer".
The KDE Software Compilation was an umbrella term for the desktop environment plus a range of included applications produced by KDE. From its 1.0 release in July 1998 until the release of version 4.4 in February 2010, the Software Compilation was simply known as KDE, which stood for K Desktop Environment until the rebrand. The then called KDE SC was used from 4.4 onward until the final release 4.14 in July 2014. It consisted of the KDE Plasma 4 desktop and those KDE applications, whose development teams chose to follow the Software Compilation's release schedule. After that, the KDE SC was split into three separate product entities: KDE Plasma, KDE Frameworks and KDE Applications, each with their own independent release schedules.
LightDM is a free and open-source X display manager that aims to be lightweight, fast, extensible and multi-desktop. It can use various front-ends to draw the user interface, also called Greeters. It also supports Wayland.
Netrunner is a Debian-based open source Linux distribution for desktop computers, laptops, netbooks and ARM-based devices.
Debian releases do not follow a fixed schedule. Recent releases have been made around every two years by the Debian Project. The most recent version of Debian is Debian version 12, codename "Bookworm". The next up and coming release of Debian is Debian 13, codename "Trixie".
The KDE Gear is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule.
KDE neon is a Linux distribution developed by KDE based on Ubuntu long-term support (LTS) releases, bundled with a set of additional software repositories containing the latest versions of the Plasma 6 desktop environment/framework, Qt 6 toolkit and other compatible KDE software. First announced in June 2016 by Kubuntu founder Jonathan Riddell following his departure from Canonical Ltd., it has been adopted by a steadily growing number of Linux users, regularly appearing in the Top 20 on DistroWatch.com's popularity tables.
Plasma Mobile is a Plasma variant for smartphones. It is currently available for the Pinephone, and supported devices for postmarketOS such as the OnePlus 6.
Q4OS is a light-weight Linux distribution, based on Debian, targeted as a replacement for operating systems that are no longer supported on outdated hardware. The distribution is known for an addon called XPQ4, which adds themes intended to replicate the look and feel of Windows 2000 and Windows XP.
KDE Plasma is a set of graphical shells developed by KDE for Unix-like operating systems. With the KDE brand repositioning in 2009, Plasma 4.4 succeeded KDE 4.3. Currently, it has four workspace variants: one for desktop PCs and laptops, one for TVs, one for smartphones, and another for embedded and touch-enabled devices. Plasma Desktop, in its default configuration, resembles KDesktop from K Desktop Environment 3 and Microsoft Windows XP; however, extensive configurability allows radical departures from the default layout.
KDE Plasma 6 is the sixth generation of the KDE Plasma desktop environment. It is the successor of KDE Plasma 5 and was first released on 28 February 2024.
