Lubuntu ( ) is a lightweight Linux distribution based on Ubuntu but using the LXDE desktop environment in place of Ubuntu's Unity shell and GNOME desktop. LXDE is touted as being "lighter, less resource hungry and more energy-efficient". Like Xubuntu, Lubuntu is intended to be a low-system-requirement, low-RAM environment for netbooks, mobile devices, and older PCs. Tests show it can use half as much RAM as Xubuntu, making it an attractive choice for installing on older hardware being refurbished for charitable distribution.〔 The name ''Lubuntu'' is a portmanteau of ''LXDE'' and ''Ubuntu''.〔 LXDE stands for ''Lightweight X11 Desktop Environment'', 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. ==History== The LXDE desktop was first made available for Ubuntu in October 2008, with the release of Ubuntu 8.10 Intrepid Ibex. These early versions of Lubuntu, including 8.10, 9.04 and 9.10, were not available as separate ISO image downloads, and could only be installed on Ubuntu as separate ''lubuntu-desktop'' packages from the Ubuntu repositories. LXDE can also be retroactively installed in earlier Ubuntu versions. In February 2009, Mark Shuttleworth invited the LXDE project to become a self-maintained project within the Ubuntu community, with the aim of leading to a dedicated new official Ubuntu derivative to be called ''Lubuntu''.〔 In March 2009, the Lubuntu project was started on Launchpad by Mario Behling, including an early project logo. The project also established an official Ubuntu wiki project page, that includes listings of applications, packages, and components.〔 In August 2009, the first test ISO was released as a Live CD, with no installation option. Initial testing in September 2009 by Linux Magazine reviewer Christopher Smart showed that Lubuntu's RAM usage was about half of that of Xubuntu and Ubuntu on a normal installation and desktop use, and two thirds less on live CD use.〔 In 2014 the project announced that it would be moving from being based upon GTK+ to Qt in what is termed LXQt. Work on this continued through the year, with the timed releases of Lubuntu being bug-fixes only to the GTK version. Lenny became Lubuntu's mascot in 2014.〔(【引用サイトリンク】url=https://wiki.ubuntu.com/Lubuntu/Marketing/Lenny )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lubuntu」の詳細全文を読む スポンサード リンク
