    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[1] such as netbooks or system on a chip computers.

    LXDE was 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.[2][3]

    LXDE uses rolling releases for its individual components (or for groups of components with coupled dependencies).[4] 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.[3] LXDE includes GPL-licensed code as well as LGPL-licensed code.[2]

    History

    [edit | edit source]

    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.

    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 suggested mobile computers with Linux distributions running LXDE 0.5 drained their batteries at a slower pace than those with other desktop environments.

    Qt port

    [edit | edit source]
    Main article: LXQt

    Dissatisfied with GTK 3,[7] Hong Jen Yee experimented with Qt in early 2013[8] and released the first version of a Qt-based PCManFM on 26 March 2013.[7]

    On 3 July 2013 Hong announced a Qt port of the full LXDE suite,[9] and on 21 July Razor-qt and LXDE announced that they would merge the two projects.[10][11][12] This merger meant that the GTK and the Qt versions would coexist for some time but, eventually, all original team efforts focused on the Qt port, LXQt.[13]

    GTK 3 port

    [edit | edit source]

    As of May 2020, there is an experimental GTK 3 port developed by the Arch Linux community.[14] GTK 3 versions have already been developed for the following components: LXAppearance, LXAppearance-ObConf, LXDE-common, LXDE-icon-theme, LXDM, LXhotkey, LXInput, LXLauncher, LXPanel, LXRandR, LXSession, LXTask, LXTerminal, Openbox, PCManFM.[15] One advantage of using GTK 3 is that GTK 3 programs run natively on Wayland. PCManFM is a popular file manager for use with tiling window managers and hence, having a Wayland-native PCManFM is useful for people that use Sway.[citation needed]

    Current development

    [edit | edit source]

    Despite the original team moving to LXQt development, some other developers continued to maintain LXDE on GitHub and, as of March 2021, there are fresh commits to keep the GTK 2 version updated. As of July 2019, the LXTerminal release is based on GTK 3 to avoid dependencies on the old VTE lib.[16][17]

    Unlike other major desktop environments such as GNOME, the components of LXDE have few dependencies and are not tightly integrated.[33] Instead, they can be installed independently of each other or LXDE itself.[34]
