Ubuntu Jaunty Jackalope on Berlin metro system

Again I am happy to announce, that Berliner Fenster, the company behind the Berlin metro tv advertisement system, viewed by approx. 1.5 million people a day, was so kind of providing Ubuntu and Ubuntu Berlin with a spot for the release of Ubuntu Jaunty Jackalope and the release party hosted by Ubuntu Berlin at c-base:

If you cannot see the embedded spot, click on this link.

The spot runs for three days, showing Ubuntu to a remarkable amount of passengers.

Happy release!

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 https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/334657, a patch has been committed to the Ubuntu repositories, that has been found here:


So the fix as an update is coming closer…

And your favorite new feature in Jaunty Jackalope is … ?

Again I’ll present a short new features from the next Ubuntu release (this time „Jaunty Jackalope“) to an audience of about 150 to 200 visitors at the upcoming traditional „Ubuntu release party“ at c-base organized by „Ubuntu Berlin“. While it’s worth noting that this event will happen on Saturday, the 25th of April, so when the release is still a hot topic, and the very friendly guys from „Berliner Fenster„, the local metro television system, are going to support release and release party by sponsoring spots, I am curious about the new features in Jaunty Jackalope that you like emphazise – be it a litte eye candy or, a command line tool or a major innovation.

After using Jaunty for about a month now I think the graphical changes really please my eyes. I like the new notification scheme (though it feels still young and there is a lot to do like implementing it to common applications like Thunderbird), introduced by Mark Shuttleworth some months ago. Moreover while not currently using Evolution myself I am impressed about reading about „evolution-mapi„, enabling Evolution to access Exchange 2000, 2003 and 2007 servers by talking the native Exchange mapi protocol and and not using the neat but slow owa (web) wrapper. Yes, that seems to be a techie feature but it might improve acceptance of Ubuntu/Gnome/Evolution in enterprise setups dramatically.

Your turn now. What is your new killer feature or just tiny improvement you like most? Let me know, and I promise, I’ll try to include it into my presentation.

Ubuntu Intrepid Ibex Release Party on 1st of November at c-base (Berlin)

So, half a year has passed and it’s time again to celebrate a new Ubuntu release. This is an invitation for you, your friends and any other human being around to join our „Ubuntu Intrepid Ibex Release Party“ on Saturday, the 1st of November, at the sunken starship c-base (Rungestraße 20), starting at 4pm.

Again, a couple of lectures will be held – ranging from new features in Intrepid (that’s my part, I’ll give the lecture at the same day also at the BLIT), over Gnome eyecandy stuff to presentations of Freifunk project and the DeepaMehta semantic desktop (don’t miss!) directly from it’s lead developer. So either if you are new to Ubuntu and want to make first steps and contact other Ubuntu users or you are a Linux guru – you’ll find somebody to have a chat with, I promise. There’ll even be a „tux tinker corner“ where you or your girl friend have the possibility to try out some Tux Origami.

The event’ll mainly be in German, but a lot of people are speaking English, so don’t hesitate asking for help/translations.

Entrance is free, there is a free wifi, so feel free to bring your notebook in. You can also „buy“ a freshly burned Ubuntu/Kubuntu/Xubuntu cd for a service charge of 1 Euro or check the Ubuntu merchandising table.

See you there?

Ubuntu landed on Berlin metro system

The guys from „Berliner Fenster“, a company responsible for the content of the television system installed inside underground vehicles (more than 3.700 displays) were so kind (thank you!) providing us with a spot for our release party this Saturday for free. So just on time with the release starting from today there are small spots viewable by an audience of about 1.5 million people per day according to their web site.

Don’t trust me? See this:

and this:

And come over on Saturday, the 26th of April to our release party. Lectures, demonstrations, freshly burned cds, a live Samba band, a button machine and Daniel Holbach as Drum’n’Bass dj and of course dozens of helpful and open source minded people are waiting for you. Entrance is free.

Daniel Holbach going to rock the turntables at Ubuntu Hardy Heron release party

I already told you about our shiny Ubuntu Hardy Heron release party on the 26th of April at the sunken starship c-base right here in Berlin, haven’t I? While the schedule is already a must-come: seven talks/presentations, not only from community members but also from friends like the Free Software Foundation Europe, a live Samba band, the chance to hang around directly at the river bank of the Spree while having free wifi turned on, I am proud to announce that our dj team just got doubled: This time Ubuntu developer and MOTU Daniel Holbach himself will bring his turntables and show us what his interpretation of a drum’n’bass dj set is. He’d just say „rock on“ and so are we. If you want to give his mixtapes a try, just check out the very category at his blog.

Hope to see you Berlin folks this Saturday (German folks even – just enter a train, car or whatever). Feel free to contact me directly there, I am always happy to see new faces.

Invitation to Ubuntu Hardy Heron Release Party in Berlin on 26th of April 2008

Here it comes: Though the release party of the „Ubuntu Berlin“ user group will be mainly in German we also invite all non native German speaking visitors to attend us. Here is the official English invitation (thanks to ninin for the work on the translation):

Ubuntu „Hardy Heron“ release party on April 26th at 4:00 pm at the c-base in Berlin

Ubuntu 8.04 „Hardy Heron“ is arriving. To celebrate the new release of the popular free GNU/Linux distribution Ubuntu the local user group Ubuntu-Berlin will organize a party. The event will take place on the 26th of April in the rooms of the culture project c-base and starts at 4:00 pm. Admission is free.

There will be a programme of short talks (about 20 minutes each) in relaxed atmosphere. Several features and applications which are integrated into the new Ubuntu version are presented by users, for example the optional 3D-Desktop. Furthermore there will be contributions of associated organisations like the „Free Software Foundation Europe“ (FSFE) and the „Förderverein für eine Freie Informationelle Infrastruktur“ (FFII). A „burning station“ provides visitors with Hardy CDs at cost price of one Euro. For anyone who wants to try out Hardy straight away there will be the possibility to do so on one of the computers there. There will be many experienced users around, who will answer questions.

Ubuntu LAN party

While dealing with preparations for our already announced Hardy Heron release party we are currently planning an Ubuntu LAN party. What does that mean? The Ubuntu Berlin team came to the conclusion that network gaming is one of the major reasons for sticking to Windows based operating systems. There is of course an unmanageable amount of games of Windows machines out there – no doubt about it. But it seems to be a prejudice that you cannot have network based gaming fun on Linux. And I don’t mean running Wine, VmWare or similar here.

Therefore we set up a small and incomplete list with games that you can play under Linux. Some of them are actually Windows games that can run under Wine – but only some (and they are a kind of compromise for some of our members). Quite enthusiastic discussions occurred in conjunction with games like „Battle for Wesnoth„, „Armagetron„, „OpenArena“ and „Nexuiz„. All of them are available through Ubuntu package repositories and – even better – not all of them are shooters.

So we are happily looking towards our first lan party within the next weeks which will be located at c-base or newthinking store if one them lets us in. I hope that we also have time to do some bug reporting afterwards if necessary – it should be a great possibility to do some network game stress tests.

Ubuntu Hardy Heron Release Party – 26th of April at c-base/Berlin (Germany)

Yes, guys, we are fast. While you might be trying the alpha 2 release of Ubuntu Hardy Heron, the so called „Ubuntu +1“, meaning the next release which is scheduled for 24th of April 2008, the „Ubuntu Berlin“ user group is already busy with preparing its release party. After our last two release parties took place at the well known c-base – a sunken star ship – and reached an audience of eigthy to hundred people, we are pleased to announce that the next party will become even bigger.

As last time several lectures will be held. Due to the public interest especially in technical information we moved our party from Friday to Saturday and are going to start earlier in the afternoon so we can provide more input for visitors while still being able to have the dj(s) do their work in the evening and probably some barbecue.

So if you live around Berlin (Germany) – save the date – and feel free to help us with the preparation. You are welcome on the mailing list or our other communication channels that you can find on our wiki page. If you are just interested in attending the lectures or just want to hang around at the party, you invited to join our moderated, low traffic announcement mailing list.
