LXQt developed from popular components of LXDE and Razor Qt project, LXQt is a free, open source, lightweight and fast desktop environment for Linux and BSD distributions. It comes with a number of great and well known features, which borrowed from LXDE desktop such as low system resource utilization, elegant and clean user interfaces.

Additionally, one of its distinguished properties is the high level of customization to meet desktop usability needs. It has been the default desktop environment on Knoppiz, Lubuntu and a few other less known Linux distributions.

Note: LXQt was initially supposed to become the successor of LXDE, however, as of 09/2016, both desktop environments will keep coexisting for the mean time and importantly, more development activity is being directed towards LXQt than LXDE.
