LXQt a.k.a the Lightweight Qt Desktop Environment, it a fork of the old-school LXDE (Lightweight X11 Desktop Environment) built against the Qt application framework instead of GTK+ and has been in development for since 2013. The latest release, LXQt 0.13.0, brings more polishing to the desktop environment and other exciting changes. For starters, all of LXQt’s components are now ready to be built against the recently released Qt 5.11 application framework, and out-of-source-builds are now mandatory. LXQt 0.13.0 also disabled the menu-cached functionality, making it optional from now on in both the panel and runner, thus preventing memory leaks and avoiding any issues that may occur when shutting down or restarting LXQt.
