KDE Plasma
also: Plasma, KDE, K Desktop Environment
KDE Plasma is a modern, feature-rich desktop environment for Linux that provides a graphical user interface, window manager, and integrated applications for everyday computing tasks.
KDE Plasma is one of the most popular desktop environments available for Linux distributions. It offers a complete, polished graphical interface built on the Qt framework, featuring a customizable taskbar, application menu, system tray, and window decorations.
Plasma includes integrated applications for common tasks: Dolphin file manager, Konsole terminal, Kontact email client, and many others. It supports multiple virtual desktops, advanced window management, and extensive theming and customization options through its Settings application.
Example: A user installs KDE Plasma on Ubuntu and immediately gets a full desktop with a panel at the bottom, application launcher, system notifications, and can right-click on the desktop to access menus—all without needing to configure individual components separately.
