Intel linux drivers and new kernel gfx support reach mature state
Thursday, October 22nd, 2009
Posted in: Intel Graphics, Karmic, Xserver ubuntu.
The Linux Kernel and the XORG video rendering have been undergoing some significant improvements in the last year, with Intel’s linux open source team bringing in a lot of refactorings an architectural improvements.
I myself suffered from the lack of support for recent integrated intel gfx cards in notebooks and thus followed the excellent Intel Linux graphics performance guide using the bleeding-edge configuration, i.e. with the latest (non-stable) builds of the xorg / intel gfx drivers and the most recent kernels. However, this configuration was (not quite unexpected) somewhat unstable and had a lot of issues.
This phase is now over. I am happy to say that after upgrading to Kernel version 2.6.32 and the xserver-xorg-video-intel driver 2:2.9.0-1ubuntu2~xup~3 the graphics support is now fast, reliable and stable. Desktop effects are back working like a charm, also in a multi-monitor setup and with sending the computer to hibernation and so forth.
I am quite optimistic that this state might make it into the upcoming Ubuntu release (Karmic), thus eliminating a lot of frustration laptop users have been experiencing with their intel gfx cards.
No CommentsCreating a PPTP VPN connections in Ubuntu 8.10 and 9.x (Intrepid, Karmic)

Posted in: System engineering, intrepid, ubuntu.
Update January 3, 2010
Configuring PPTP VPN connections still is sort of an issue with the recent Ubuntu versions,
thus most of the information on this page still is relevant.
Update December 8, 2008
The following solution does not work for everybody as there are multiple issues with VPN connections, the network manager etc. Bug fixing is in progress and it appears a number of patches where already included in recent ubuntu updates.
I recommend checking the ubuntu bug database for the latest state of the VPN issues:
Search for “VPN” in the ubuntu bug database (launchpad.net)
This monday was sweet. I finally had the time to make a fresh install of ubuntu 8.10 on my thinkpad r52, and what can i say, just as all the other releases before, things got better.
I am especially happy about the re-programmed network manager, which works a whole lot better than in hardy.
Except that i didn’t get the PPTP VPN connection to my office to work instantly.

Configuring Eclipse Ganymede with subversion in Ubuntu 8.04
Sunday, July 13th, 2008
Posted in: J2EE, SCM, System engineering, eclipse, java, subclipse, subversion, subversive, ubuntu.
After installing the all-new Eclipse ganymede (by downloading it from the eclipse site) under ubuntu 8.04 i ran into some trouble after installing version 1.4.1 of the subclipse subversion plugin.
Long story short, subclipse requires subversion 1.5, but ubuntu 8.04 provides 1.4.x.
If you still want to use subclipse with ganymede in ubuntu, there are only two ways two achieve this – both of which i cannot recommend because they are hacks or bad compromises.

Works like a charm.
Critical security vulnerability in debian openssl package
Wednesday, May 14th, 2008
Posted in: System engineering, debian 4, ubuntu.
Debians security advisory has reported a critical security issue with debian-based openssl packages.
As a result,generated keys might be weak and breakable, since the random number generator appears to have created predictable results.
The exact nature of this predictability was not made public by now, but it is strongly recommendet to regenerate keys created with kryptographic tools affected by the issue and to re-enroll all corresponding certificates.
Note that his issue affects all debian-based systems, including ubuntu 8.04.

Seems i’ll have a somewhat busy weekend.
No CommentsUbuntu 8.0.4 LTS is out, and it rocks!
Thursday, April 24th, 2008
I just upgraded to the latest 8.0.4 ubuntu release and i am more than satisfied.
In fact, i believe that the improvements (performance, network support, display and gfx card support, encryption and many more) are just about the same huge step forward that 7.10 was compared to the release 6.
After the automatic update, i had firefox 3 (lovely from the start), improved SSH authentication support (better protection of private key etc.) and finally, my wxga display AND laptop monitor configured perfectly even with my not-so standards conform internal GFX card (Intel 950m, in fact).
What else is there at the first glimpse? Improved language support and a nice little search engine (Conceptual rip of from apple i must admit, but well done!) for all kinds of items on your hard disk, and a really sweet new background image. For the artist in the nerd.
Yes, i’m charmed. I recommend it! Especially since it’s a long term support release…

Posted in: Uncategorized, latex, ubuntu.
Wer seine Arbeiten mit Latex verfassen möchte wird oft von der schier endlosen Masse von Paketen, Versionen, Tools und Konfigurationen erschlagen, die mit dieser an sich recht einfachen Sprache einhergehen. Ich kam neulich wieder in dem Umstand einen Artikel mit Latex zu verfassen, und habe mir zu diesem Zweck Tools und Pakete unter Ubuntu 7.10 (Gutsy Gibbon) herausgesucht, mit denen ich insgesamt mehr als zufrieden war. Eine kurze Beschreibung und Installationsanleitung.
Update: Alle hier beschriebenen Pakete sind auch in Ubuntu 8.04 unterstützt und funktionieren dort auf die gleiche Weise.

No Commentsmaven autocompletion für die shell (und windows)
Wednesday, March 26th, 2008
Posted in: System engineering, java, maven 2, ubuntu.
Beim Arbeiten mit maven stört die fehlende automatische Vervollständigung auf der Kommadozeile, insbesondere wenn man den Komfort einer ordentlichen unix-shell gewöhnt ist. Doch dem kann abgeholfen werden. Aktuelle Linux-Distributionen (und unter Windows CYGWIN) besitzen mit bash-completion eine einfache Schnittstelle zum Erweitern der Autocompletion.

Sourcecode in Wordpress mit Syntaxhighlighter plus
Saturday, January 19th, 2008
Für Sourcecode in Wordpress gibt es auf den offiziellen wordpress plugin Seiten eine überschaubare Anzahl passender Plugins.
Ich habe mich für Syntaxhighlighter plus entschieden, da das auch mit der von debian 4 momentan unterstützten Wordpress-Version 2.0 zusammenarbeitet, und bin hochzufrieden damit.
Die Installation war problemlos, aber das Layout sah anfänglich etwas zerschossen aus, Read the rest of “Sourcecode in Wordpress mit Syntaxhighlighter plus”
