Summer of Code slots available for LXDE through Debian

There are still opportunities for people interested in working on LXDE as a summer of code project. We are in touch for example with the Debian project, who offered to give spots to students from the LXDE project for example for a better integration. Also, new student projects are welcome. The summer of code program offers student stipends of 4500,- USD for studying and development work on specific free and open source projects.

Please check it out and apply as soon as possible. Also get in touch with us, so we can support your application.

The Debian program is at: and and on #debian-soc on

The application deadline is approaching soon. It is important to apply before 19:00 UTC April 3rd. Applications can still be adapted and specified with mentors after that date. You might regard your first application as a version 0.1 maybe. So, please, dont be shy. Good luck!


LXDE Summer of Code Projects – Apply now

The Google Summer of Code is now accepting applications from students for projects. There are a number of projects, that could accept LXDE related works. If you have an idea we are open to support you and discuss it. Please join us in the LXDE channel on I would also like to support you and endorse any applications by talking to projects directly. Just let me know, please.

Here is a list of projects related to LXDE.

For a full list look here:

Did I forget any relevant project? Please leave a comment then.

As a side note, I am also the administrator of the Freifunk project in GSoC, which is an OpenWrt based firmware. Generally we are looking for any good ideas related to mesh networks. So get in touch with me if you have any ideas: Freifunk

LXDE on OpenSolaris

Alfred Peng from Wuhan, China started to port LXDE to OpenSolaris. I met him in Singapore and could see how it is running already pretty smoothly.

Opensolaris with LXDE

Since it’s a GTK based desktop environment, some of the applications (pcmanfm, lxpanel, lxappearance, lxlauncher etc.) can be easily built and installed. But some still don’t work. The network manager lxnm is one of them, also lxtask and lxterminal. Good news is that the OpenSolaris nwam manager works great with small memory footprint :) The app lxmusic, which is the media player for LXDE, depends on xmms libraries. This could be a limitation for the distribution as xmms links against a lot of patented codecs. Maybe GStreamer framework could be a better choice from a distribution’s point of view. Anyway, I can still use Songbird/Rhythmbox/Totem.

To compare with my personal experience of Xfce, LXDE runs better on OpenSolaris. Xfce is a little bit sluggish on my box (configuration issue?). LXDE’s performance and memory footprint are really impressive to me. It provides a nice alternative for the resource-limited desktop users (Eee PC users for example). On the other hand, the desktop layout of LXDE is pretty similar with Windoz. I guess this is because a big bunch of the developers are from Taiwan :) This helps easier migration for users from the Windoz land. As the LXDE applications are still in the 0.x stage, please feel free to get in touch with the community (mailing list or IRC) for any problems you find.

The first set of spec files have been checked in to the SFE reporitory (SFElx*, SFEgpicview, SFEgtknetcat, SFEopenbox and SFEpcmanfm). If you’re familiar with CBE, it’ll be very easy for you to build and install LXDE on OpenSolaris. Those who are interested can also refer to the CBE instructions.

Actually the porting initiative comes from Mario Behling‘s introduction of LXDE on the Singapore Linux meetup group event in January. The frozen-bubble porting was also after the event :) It’s nice to talk with him face to face and get to know a lot of community people behind: pcman, jserv and many more in the Asia region. Stay tune, I believe there will be more to come from LXDE community. (

LXDE at Chemnitzer Linuxtage 2009

The feedback on LXDE at the Chemnitzer Linuxtage in Germany has been fantastic. Klaus Knopper presented LXDE as a default on Knoppix. Christoph Wickert showed how to install LXDE on different systems and Marcus Schulderisnky introduced people to ways to translate LXDE. Here are voices from the blogosphere.

Making USB Sticks with LXDE at the Chemnitzer Linuxtage 2009

LXDE was a very important topic. We created USB-Sticks of Christoph Wickert’s LiveCD with LXDE on the visitors USB-Sticks.
Simon Wesp (Cassmodiah auf #lxde),

Ein kleines Highlight für mich war: Christoph Wickert schult Klaus Knopper in einer Knoppix-Vorlesung über LXDE! :-p

Jörg Simon (unser verantwortlicher Ambassador für den CLT> LXDE on Fedora was the Superstar this year – and what could be better

Max Spevack:

Und noch ein paar andere Reaktionen, die ich gefunden habe:

Translation update!

New week and time for an update regarding the translations for LXDE. During the last week some more users have started the translations in Pootle and by all means have delivered. Significant changes are noted in Danish that are 100% complete by now, good work!

If you are new to Pootle and/or translation in general take a look at the crash course at the LXDE wiki and then go grab some strings. Just some spare minutes are needed to make some languages 100% complete, others could benefit a great deal from just some minutes of work and that coul add up to a complete translation. Start with the low hanging fruit, skip LXPanel if you are not too familiar with doing translations.

By now the following languages are complete:
– Danish
– Indonesian
– Polish
– Portugese (Brazilian)
– Slovak
– Swedish

And in close range of 100% is the following:
– Arabic (one string marked fuzzy in LXPanel)
– Ukrainian (one string marked fuzzy in LXLauncher, in fact it is untranslated!)
– Czech is at 87% (only LXPanel left, over two thirds are already done)
– German at 84% (missing strings in LXPanel, LXLauncher and LXMusic. The last two is small and pretty easy to finish I guess)

For the other represented languages more actions are needed to make them complete, some are close to 80% with others only done in LXMenu-data that we have imported from GNOME.

Summer of Code: Please submit your project ideas

Google Summer of Code

I have submitted our application for the Google Summer of Code 2009 and we are looking forward to the participation of the LXDE project. We are applying with LXDE and PCMan File Manager as dedicated software projects.

We are gathering project ideas for LXDE in the wiki.  If you are interested to join LXDE at the summer of code and would like to discuss project ideas, please also join us on IRC at #lxde.

Ideas for the PCMan File Manager project are on a seperate project page here: PCMan File Manager Ideas. The pages will be continuously updated with more information starting at the week from Monday, March 16, 2009.

Please visit our idea pages and add your project ideas. We are looking forward to your involvement and contributions!

LXDE on ARM architectures: Sharp Zaurus

Zubuntu with LXDEThe LXDE project is pushing its way onto the market for mobile devices and ARM architectures. LXDE is now available for Sharp Zaurus in a specialized Ubuntu Linux distribution (Ubuntu 8.04 Hardy Heron) called “Zubuntu”. Zubuntu is developed by hacker Omegamoon and can be booted (mostly) from flash memory.

The Zubuntu project was inspired by Nokia’s Handheld Mojo project, which is porting Ubuntu to the ARM architecture. In creating his root filesystem for the Sharp Zaurus, Omegamoon drew pre-built binaries from the ARMv5EL (ARM9) branch of Mojo Project’s Frisky Firedrake tree. (

Major changes:
* Fix icon display problems under 64-bit systems.
* Fixes to work with minimization animation provided by window manager.
* Fix RTL problems of the task list.
* Launch console applications in terminal properly
* Some minor bug fixes

Please install menu-cache and lxmenu-data first. Otherwise you’ll get
no application menu.

Cheers and happy Chinese New Year! 恭喜发财,牛年大吉!

New download page for LXDE

Mwei in Taiwan and me (Mario) in Germany have set up a new download page for LXDE on


The page currently features a Live-CD version and USB version of pud, which was put together by Penk, who is also a LXDE contributor from Taiwan. LXDE/PUD GNU/Linux is an Ubuntu-based mini distribution based on LXDE. Pin-Shiun Chen is the developer of this special version: “This edition of live CD is made for the Lightweight X11 Desktop Environment (LXDE), including the newest LXDE 0.3, installer and Ubuntu 8.04 packages.”
