Lubuntu is an official derivative of the Ubuntu Linux distribution that uses LXDE as desktop environment. The operating system is designed for old and weak hardware, such as the live CD runs on a Pentium II with 350 MHz and 128 MB RAM. By using the Openbox window manager, this Linux distribution still needs less memory than Xubuntu.

The name Lubuntu is composed of LXDE and Ubuntu, like Kubuntu (KDE and Ubuntu) and Xubuntu ( Xfce and Ubuntu). Here LXDE stands for " Lightweight X11 Desktop Environment ".


Since Ubuntu 8.10 " Intrepid Ibex " was the desktop environment LXDE on the package sources available for installation. In February 2009, Mark Shuttleworth invited the LXDE project to be a separate project within the Ubuntu community to long term produce a new official Ubuntu derivative called Lubuntu. Lubuntu has started ( Intrepid Ibex Ubuntu version 8.10 ) by Mario Behling as a community project on Launchpad in March 2009. Since August 2009, is a Lubuntu live CD available, which, however, was initially delivered even without installation option. A goal of the developers was to be recognized by Canonical as an official Ubuntu derivative. This goal was achieved at the Ubuntu Developer Summit in May 2011. The first officially supported version is the version published in October 2011, 11:10, codenamed " Oneiric Ocelot ". Lubuntu 12:10 " Quantal Quetzal " followed in October 2012, this version requires first a CPU with Physical Address Extension which applies to CPUs from the series Intel Pentium Pro and AMD Athlon (K7 ). The presence of PAE is checked by the installer, as some models of the much younger Intel Pentium M series but it does not provide the ability to correct, a workaround has been published. On 19 June 2013, the city of Munich decided to distribute during the year a total of 2000 free Lubuntu installation CDs to offer Windows XP users before the expiry of the support phase a replacement and thus avoid electronic waste according to the request of the ODP. Lubuntu was chosen because it is a " proven and widespread Linux version with low system requirements, which can be similar to Windows XP install and operate " is. Since Lubuntu at the time did not offer LTS version, Ubuntu 12:04 LTS was distributed.



DEFT, LXLE and Peppermint OS are derivatives of Lubuntu.
