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.

A big thank to everyone involving in the development of this new great release : LXDE developers, Ubuntu developers, ISO testers, artwork and design people, social-network & blog writers, support & IRC keepers … It’s another success of a great team work 🙂


Blueprint for lubuntu 12.10

Julien Lavergne started a blueprint for lubuntu 12.10. It’s a summary of tasks we are planning for 12.10. It should be the base of the discussions we will have at UDS and afterwards. The blueprint is here:

“You can use the white-board for comments. But, if you want to start a discussion for an application by default, you need some good reasons / objective arguments. You can also start a new thread on the mailing, if you want a separate discussion, but be sure to add a link to the blueprint so we keep it in mind during the discussion. The plan is to add all the topics to discussion for UDS. I would like to end the discussions about the applications by default after UDS, so we can focus on integration and testing.”

Lubuntu Lucid Alpha 3 “Preview 3”

Julien Lavergne has released the next Alpha 3 of lubuntu.

The Lubuntu Lucid Alpha 3 is now available. It is build with Ubuntu Lucid (10.04) which is still in Alpha state of development, so same warnings: “Pre-releases of Lucid are *not* encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage.  They are, however, recommended for Ubuntu developers and those who want to help in testing, reporting, and fixing bugs.” We passed Feature Freeze, that mean most of the features should now be available. It’s now time for testing and fixing bugs.

New features since Alpha 2 :
* Main changes in the seed :
 – chromium for the browser
 – gnome-mplayer for the videos
 – network-manager for the network
* pcmanfm2, the rewrite of the file-manager, is now used by default.
* New artwork made by Rafael Laguna.
* A new session (Lubuntu-Netbook), which launched lxlauncher. You need to logout, select Lubuntu-Netbook session instead of Lubuntu, and enter login “ubuntu” without password.
Known bugs:
* If you test on a USB, the first screen will freeze for a moment when you click on “Try Lubuntu …”. Just wait, it will continue as normal.
* Bug reported during testing :
* Specific pages for pcmanfm2 bugs :

If you want to create a bootable usb system, please use the usb creator directly on Ubuntu. Please follow the testing process described on this page: . You can also report problems and bugs relative to the tests on this page. Download :
