LXDE

LXDE (abbreviation for Lightweight X11 Desktop Environment) is a free desktop environment with comparatively low resource requirements. This makes it especially suitable for use on older or resource-constrained personal computers[2] such as netbooks or system on a chip computers.

Overview

LXDE is written in the C programming language, using the GTK 2 toolkit, and runs on Unix and other POSIX-compliant platforms, such as Linux and BSDs. The LXDE project aims to provide a fast and energy-efficient desktop environment.[3][4]

In 2010, tests suggested that LXDE 0.5 had the lowest memory-usage of the four most-popular desktop environments of the time (the others being GNOME 2.29, KDE Plasma Desktop 4.4, and Xfce 4.6),[5] and that it consumed less energy,[6] which suggests mobile computers with Linux distributions running LXDE 0.5 drained their batteries at a slower pace than those with other desktop environments.

LXDE is the default desktop environment of Knoppix, LXLE Linux, Artix and Peppermint Linux OS - among other distributions. For many years it was the desktop for Lubuntu until replaced by LXQt in 2018. Further the PIXEL desktop environment of Raspberry Pi OS (formerly Raspbian, the official Raspberry Pi operating system) is a highly modified version of LXDE.

LXDE uses rolling releases for its individual components (or for groups of components with coupled dependencies).[7] The default window manager used is Openbox, but one can configure a third-party window manager for use with LXDE, such as Fluxbox, IceWM or Xfwm.[8] LXDE includes GPL-licensed code as well as LGPL-licensed code.[3]

History

The project was started in 2006 by Taiwanese programmer Hong Jen Yee (Chinese: 洪任諭; pinyin: Hóng Rènyù), also known as PCMan, when he published PCManFM, a new file manager and the first module of LXDE.

Comparing Linux distribution rankings for DistroWatch in early January 2011 for the year 2010 versus 2009, Ladislav Bodnar noted the increase in popularity of LXDE versus other desktop environments. He said:

Looking through the tables, an interesting thing is the rise of distributions that use the lightweight, but full-featured LXDE desktop or the Openbox window manager. As an example, Lubuntu now comfortably beats Kubuntu in terms of page hits, while CrunchBang Linux, a lightweight distribution with Openbox is still in the top 25 even though it failed to produce a stable release for well over a year. Many other distributions started offering LXDE-based editions of their products, further contributing to the dramatic rise in popularity of this relatively new desktop environment.[9]

Qt port
Main article: LXQt

Dissatisfied with GTK+ 3,[10] Hong Jen Yee experimented with Qt in early 2013[11] and released the first version of a Qt-based PCManFM on 26 March 2013.[10]

On 3 July 2013 Hong announced a Qt port of the full LXDE suite,[12] and on 21 July Razor-qt and LXDE announced that they would merge the two projects.[13][14][15] This merger meant that the GTK+ and the Qt versions would coexist for some time but, eventually, the GTK version would be dropped and all efforts focused on the Qt port.[16]

Software components of LXDE

Unlike other major desktop environments such as GNOME, the components of LXDE have few dependencies and are not tightly integrated.[17] Instead, they can be installed independently of each other or LXDE itself.[18]
