Welcome to the LXQt Desktop Portal edit
LXQt is the Qt port and the upcoming version of LXDE, the Lightweight Desktop Environment. It is the product of the merge between the LXDE-Qt and the Razor-qt projects: A lightweight, modular, blazing-fast and user-friendly desktop environment.
It is a fast and stable desktop environment already usable on production systems that will not get in your way. It will not hang or slow down your system. It is focused on being a Classic Desktop with a modern Look & Feel.
Available on openSUSE and most Linux and BSD distributions.
See the main LXQt wiki page.
