Lubuntu is a lightweight Linux distribution based on Ubuntu, using the LXQt desktop environment in place of Ubuntu’s GNOME desktop. Lubuntu was originally touted as being “lighter, less resource hungry and more energy-efficient”, but now aims to be “a functional yet modular distribution focused on getting out of the way and letting users use their computer”.
The name Lubuntu is a portmanteau of LXQt and Ubuntu. The LXQt name derives from the merger of the LXDE and Razor-qt projects, while the word Ubuntu means “humanity towards others” in the Zulu and Xhosa languages.
Lubuntu received official recognition as a formal member of the Ubuntu family on 11 May 2011, commencing with Lubuntu 11.10, which was released on 13 October 2011. (from Wikipedia)
