Lubuntu 12.04 is now available

Julien Lavergne and the team have released lubuntu 12.04.


What is Lubuntu

Lubuntu is a flavor of Ubuntu based on the Lightweight X11 Desktop Environment (LXDE), as its default GUI.  The goal is to provide a very lightweight distribution, with all the advantages of the Ubuntu world (repositories, support, etc.). Lubuntu is targeted at “normal” PC and laptop users running on low-spec hardware. Such users may not know how to use command line tools, and in most cases they just don’t have enough resources for all the bells and whistles of the “full-featured” mainstream distributions.

With many LXDE components, Lubuntu also uses well-known applications, such as Chromium, Openbox, Pidgin, to name a few. The Lubuntu project wiki contains more information on the project and the applications used available.

Unlike Ubuntu, Lubuntu 12.04 is not a LTS, this version will be supported for 18 months. However, a lot of work has been done to improve the stability of the system.


* Based on the lightweight LXDE desktop environment.
* Pcmanfm 0.9.10, a fast and lightweight files manager using gio/gvfs.
* Openbox, the fast and extensible, default windows-manager of LXDE.
* Lightdm, using the simple GTK greeter
* Chromium, the open-source version of Google Chrome.
* … and, of course, based on Ubuntu 12.04 LTS.

Improvements since Lubuntu 11.10

* A new software-center, optimized to be lightweight, for easy installation and removal of applications from your system.
* New theme is used, and each previous themes are available in the repositories.
* Lightdm is used as the display manager with the default gtk greeter.
* Blueman is now used instead of gnome-bluetooth for managing bluetooth devices.
* A lot of bug fixes, especially on the panel and the file manager.

12.04 Life of a bug

On Wednesday 18th Jan 2012 I was having problems with my updated test image of 12.04. It installed well and the bug that was affecting the selection of the language appeared to have been squashed (That bug lived a short life, it’s history can be found at ) But, more worryingly, when I started the new install my Virtual Machine went ‘crazy’… Screen kept resizing and eventually it just fizzled out and hung. As there was the weekly QA (Quality Assurance / Testing) meeting scheduled for 5pm (UTC) [1] I asked about it on there when we got to the agenda item for Lubuntu. Fairly quickly one of the other QA team had verified the problem and more importantly had gotten a error message. Things move on quite quickly when we have a critical bug that prevents the install from working. The daily builds for lubuntu are generated at about 5:30pm UTC, so after the meeting myself and njin both updated our install images and tried again. At about 5 minutes to 8pm when the weekly Lubuntu meeting [2] takes place we both confirmed said bug was still present. At about 8:15pm I was asked to give my report to lubuntu team about QA, I presented what was pretty much breaking news along with what information we had. The meeting progressed and finished. Immediately after the meeting our head of development (Julien) had a dig into what was going on and raised a bug report ( ). Within  5 hours the cause was found as is being chased. I’ll give an update once I have some more news.

For those of you whos interest in the importance of testing has been hightened, may I point you to where you will find how to contribute and the list of the various Sub Teams, including the QA one for lubuntu.



The development of 12.04

With the launch of 11.10, the developbers have a very brief breathing space as ideas not implemented in 11.10 are carried over. One such ‘carry over’ was the Lubuntu Software Center. To kick start the 12.04 cycle there was the Ubuntu Developers Summit with Lubuntu there as a fully fledged member of the familiy 🙂
