LXQt is a bundle of software packages under development, with the aim of providing a complete desktop environment. It was formed from the merger of the LXDE and Razor-qt projects.


Dissatisfied with GTK+ 3,[3] Hong Jen Yee experimented with Qt in early 2013[4] and released the first version of a Qt-based PCManFM on 26 March 2013.[3] 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.[5]

On 3 July 2013 Hong Jen Yee announced a Qt port of the full LXDE suite,[6] and on 21 July 2013, Razor-qt and LXDE announced that they decided to merge the two projects.[7][8] 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.[7] The merger of LXDE-Qt and Razor-qt was renamed LXQt,[9] and the first release, version 0.7.0, was made available on 7 May 2014.[10] Version 0.8.0, bringing with it full Qt 5 compatibility, was made available on 13 October 2014.[11]

LXQt version 0.9 was released in February 2015, featuring heavy internal cleanups and refactorings. All compatibility with Qt 4 was dropped, requiring Qt 5 & KDE Frameworks 5. Qt 5.3 is now the minimum required version.[12]

LXQt version 0.10 was released in November 2015.[13]

LXQt version 0.11 was released on 24 September 2016.[2] To address concerns that Qt-based apps have heavy memory usage, this release was compared against Xfce, revealing that, after a cold boot, LXQt's memory usage was of 112 Mb, just a bit less than Xfce.[14]

LXQt consists of many modular components, some of them depending on Qt and KDE Frameworks 5.[15]
