Desktop Summit 2011 in Berlin

I am happy to announce that Berlin has been chosen as location for the Desktop Summit 2011. If you don’t know so far: Desktop Summit is a 1000+ developer conference co-hosting KDE’s „Akademy“ and GNOME’s „GUADEC“ at the same time:

Read the press release: Desktop Summit 2011 Announced

As Ubuntu member and head member of c-base e.V. I am part of the Berlin team, together with Claudia Rauch from KDE e.V. and Mirko Boehm of KDE. Let me quote Mirko:

„We are honored and proud that our proposal was selected. What we look forward to the most is the inspiration our communities will draw from having the Desktop Summit together again, but also from visiting our bustling, welcoming city. We would like to thank all the supporters of the proposal, and will work hard to make the conference a big success.“

I am sure this event will become a success. And it’s a great opportunity to meet and greet across the letters before the „U“ in „Ubuntu“.

Ubuntu Berlin @ LinuxTag 2010 – pickings

Saturday evening this years LinuxTag, Europes largest open source fair, closed its doors. As LinuxTag is presented at Berlin, the „Ubuntu Berlin“ was happy to support it in different activities. Let me sum up some of them:

1) Ubuntu Community booth

The „ubuntu Deutschland e.V.“, Ubuntu and Kubuntu community presented their work at a community hosted booth. A bunch of Ubuntu Berlin members supported the booth, answered hundreds of questions and helped with the proceedings.

2) Talks

Saturday Featured a lot of Ubuntu focussed talks. For the first time „Ubuntu Berlin“ and its members hosted a remarkable amount of them, e.g.:

  • Anselm Helbig – Ubuntu Berlin Lightning Talks (tmux)
  • Benjamin Drung – Ubuntu in 50 minutes, Packaging for Debian and Ubuntu
  • Caspar Clemens Mierau – Ubuntu Berlin Lightning Talks (Vimperator), Gnome-Do, Ubuntu in 50 minutes
  • Daniel Holbach – Fixing Bugs in Ubuntu (see slides), Ubuntu in 50 minutes, Ubuntu Berlin Lightning Talks (liblaunchpad)
  • Marcel Eichner – Ubuntu Berlin Lightning Talks (Franklin)
  • Torsten Franz – Supporting Ubuntu

3) Interviews for Radio Tux

Several members of Ubuntu Berlin gave interviews to the well known German Podcast „Radio Tux„. Daniel’s talk on bugjamming has been released already. Be sure to check the archive for other releases within the next days.

4) LinuxTag BBQ

Last but not least: The  „End of LinuxTag BBQ“ at c-base, sponsored by Canonical, has been a great success again. Three barbacues and about ten „Grillmeister“ (you cannot translate this) provided more than hundred visitors with tasty food. Members of various types of open source communities had interesting chats while relaxing at the banks of the Spree.

As Ubuntu Berlin’s support for the LinuxTag continuously increased within the last years, I am sure next year will even better. We’ll see.

possibly scrambled qt4 apps in Ubuntu Jaunty Jackalope while using VRGB and LCD

In less than 48 hours Ubuntu Jaunty Jackalope will be released officially! While using Jaunty for more than a month I am pleased to see this great new release getting it’s way to a huge usership. While preparing my small „new features in Ubuntu Jaunty Jackalope“ talk for the „Ubuntu Berlin“ release party at c-base, I’d like to point out one open bug, that will make it into the release and might get some users into strange trouble:

When you have – for whatever reason (either by chance, clicking around or due to having a rotated display) – changed the display mode of Ubuntu to VRGB or VBGR (you can easily do this in the „System>Preferences>Appearance>Fonts“ menu) and additionaly turned on the lcd/subpixel mode, probably all of your qt4 applications – even qtconfig – will be totatlly scrambled and unreadable. The bug might hit you under Ubuntu (without a blue „K“ in the beginning) as you probably run something like VirtualBox, Skype or even Amarok in your Gnome environment. It will probably look like this:

But: Don’t panic! This bug only occurs when you changed some defaults in the Appearance/Fonts settings to rather uncommon or often maybe useless settings and switching back is fairly easy. But as I ran into this and put some effort into the corresponding bug on launchpad Subpixel/Lcd mode with VRGB/VBGR makes qt4 applications on Jaunty unreadable, I noticed, that a remarkable bunch of users posted duplicate bug reports or commented the report.

So if you are running into this error, all you have to do, is:

  1. exit all qt applications,
  2. go into „System>Preferences>Appearance>Fonts“,
  3. change VRGB/BGR to RGB/BGR.

That’s all. If you want to examine the bug, do the following (don’t do this at home):

  1. exit all qt applications,
  2. go into „System>Preferences>Appearance>Fonts“,
  3. change RGB/BGR to VRGB/BGR,
  4. switch to lcd/subpixel mode.

Afterwards your qt applications will look scrambled. If you don’t know, which one to run for a test, you probably have „qtconfig“ installed.

(I had a little chat with some developers about the severity of this bug. Though I think it’d would be definitely better not having it in a release, I understand the point, that the environment must be set up in a rather special way to run into this and it popped up quite late. Therefore it did not make it into the release critical bugs, but I am quite sure, it will be fixed soon.)

That’s all about this. I wish you a smooth upgrade to Jaunty – see you there :)

[update 2009-04-03]

As you can read on, a patch has been committed to the Ubuntu repositories, that has been found here:

So the fix as an update is coming closer…

Ubuntu Berlin raising money for a video projector – want to support?


I already mentioned that one goal of Ubuntu Berlin for this year is raising enough money for a new video projector. The „Ubuntu Berlin“ team is quite active with its release parties, bug jams, lectures and workshops and most of these events require us to present software to an audience (surprise!). We are really happy about having the possibility to use the infrastructure of the well known c-base, but the video projector there is really close to its end of life-cycle and more or less unusable (too dark, unsharp, etc.).

Therefore we decided to buy a new video projector funded by the community. The „ubuntu Deutschland e.V.„, the main German LoCo team, if you can say so, and legal association behind major parts of the German community, is able to collect the money and can even issue an official contribution receipt as this is tax deductable in Germany.

So if you have some money left and want to support one of the most active teams in the Ubuntu community, feel free to donate some money to:

account holder: ubuntu Deutschland e.V.
bank: HVB Nürnberg
account number: 382916859
bank code: 76020070
IBAN: DE44760200700382916859

Swift (BIC)
purpose of transfer: „Ubuntu Berlin“ (important!)

Of course you can also donate money from another country than Germany, just use the IBAN/Swift :)

For your information:

We intend to buy a projector for about EUR 500 to 700, depending on the amount of money we collect. The beamer will be a permanent loan to the c-base, located in their workshop room – therefore used for hundreds of lectures and workshops around free software. If we collect more than we actually need for the projector, we’ll spend the remaining money for other expenses connected to Ubuntu Berlin (e.g. further reconstruction of the workshop room at c-base, funding of our bigger events like LinuxTag BBQ, release parties, etc.).

Thanks for reading, and: Donating makes you really sexy :)


You can also donate money over the wire: Just send the amount of money you like to spend via PayPal to: [email protected]

Ubuntu BBQ on 31th of May – End of Linuxtag

Ubuntu Berlin strikes again! On the 31th of May, this Saturday (and last day of the „Linuxtag“), Ubuntu Berlin is proud to present the „Ubuntu BBQ“ – an event you should not miss when staying in Berlin for attending „Linuxtag 2008„, live here or happen to be around by chance.

Hosted again by the sunken starship „c-base“ we are happy to provide you with drinks at low prices, and BBQ and entrance for … free! Sponsorships from Canonical Ltd. (you might have heard of them) and ubuntu Deutschland e.V. (thank you!) and an invitation from the Linuxtag Community staff made this possible and we are anxious to see how many Linuxtag attendees make their way to the base.

But it’s not about eating and drinking: The event gives you the possibility to meet a lot of GNU/Linux and Ubuntu interested folks, even some of the well known free software gurus in a relaxed atmosphere. Of course you can use a free wifi network with you notebook/gadget/whatever, but don’t forget: It’s a party. Music will be around and you can sit directly at the rivercoast of the „Spree“. It’s said the weather will be great.

You are invited the join us starting from 4 pm – the BBQ will start from 7pm – so you have enough time to come over from Linuxtag. We will arrange some groups you can join on Linuxtag making it easier for you to find the c-base. See more on our (yet only German) announcement.
