LXQt is a free and open source Linux desktop environment, that was was formed from the merger of the LXDE and Razor-qt projects.

History[edit]

Dissatisfied with GTK+ 3,[2] LXDE maintainer Hong Jen Yee experimented with Qt in early 2013[3] and released the first version of a Qt-based PCMan File Manager on 26 March 2013.[2] He clarified, though, that this means no departure from GTK+ in LXDE, saying "The Gtk+ and Qt versions will coexist". He later ported LXDE's Xrandr front-end to Qt.[4]

On 3 July 2013 Hong Jen Yee announced a Qt port of the full LXDE suite,[5] and on 21 July 2013, Razor-qt and LXDE announced that they decided to merge the two projects.[6][7] This merge means that the GTK+ and the Qt versions will coexist at first but that, eventually, the GTK+ version will be dropped and all efforts will be focused on the Qt port.[6] The merger of LXDE-Qt and Razor-qt was renamed LXQt,[8] and the first release, version 0.7.0, was made available on 7 May 2014.[9]

With the 0.13 release on 21 May 2018 the LXQt project formally split from LXDE with the move to a separate Github organization.[1]
