LXDE (Lightweight X11 Desktop Environment) is an open-source, lightweight and energy efficient desktop environment for Linux and other Unix-like operating systems. It is designed to be fast, user friendly, and to require relatively low system resources in order to run. It is based on the GTK+ toolkit and uses the Openbox window manager by default. LXDE is designed to be as efficient as possible in terms of system resource consumption, and uses fewer system resources than most other desktop environments. It is designed to be used on a wide range of hardware, including netbooks, laptops, and other low-spec devices. It features a simple and intuitive user interface, with a taskbar, start menu, and desktop icons. The applications included in the LXDE package are lightweight, and are designed to be fast and responsive. LXDE is also highly configurable, allowing users to customize the look and feel of the desktop environment. Users can choose from a variety of themes, and can customize the window manager, desktop background, and other settings. LXDE also includes a range of applications, such as a web browser, media player, image viewer, and text editor. LXDE is an ideal choice for users who need a lightweight, user friendly, and energy efficient desktop environment. It is also a great choice for users who want a highly customizable and configurable desktop environment.
The main goal of LXDE is to be light, fast and energy efficient, which GNOME never was.
