Lubuntu is a free and open source lightweight official flavor of the Ubuntu desktop operating system. It originally had the LXDE desktop but as of 18.10 comes with the LXQT desktop.

Lubuntu is a complete Operating System that ships the essential apps and services for daily use: office applications, PDF reader, image editor, music and video players, etc.

  • Ubuntu based – Built with a rock-solid Ubuntu Linux base, with thousands of free apps available and virus-free from the safe Software Center.
  • Compatible – Use all your music, PDFs, documents and files, and share them with other computers and operating systems.
  • Fast and lightweight – Designed to be fast, friendly, and energy saving, from Open Source software with a great supporting community behind.
  • New inside and outside – Lubuntu now ships the most advanced desktop interface, using Qt technologies for rendering the widgets and the entire ecosystem (from the installer to the smallest parts). The winning combination of Arc theme and the Papirus icons makes the new Lubuntu desktop easier to read and less cluttered. The symbolic icons and glyphs, now easier to recognise, added to sharp edges and vibrant colours, add visual dynamics without overwhelming the overall design. Combined with the new compositing effects, the apps, panels and widgets of your new desktop will look modern, while being fast, simple and affordable for almost every machine. — Lubuntu home page.
