KDE 4.3: Enable Desktop Search in Kubuntu 9.04

First make sure that all required packages are installed. You need these packages:

• sun-java6-bin
• strigi-daemon
• soprano-daemon
• soprano-backend-sesame
• kdebase-runtime
  

Optional packages:

• kdegraphics-strigi-plugins
• kdesdk-strigi-plugins
• kdepim-strigi-plugins

Update 2009-11-02: With Karmic Koala the steps below are no longer necessary. Just install the packages from above (these are not installed by default) and enable the Strigi Desktop File Indexer in the Desktop Search control module.

Then follow the comment #19 in the bug report:

1. As root user edit the file /etc/ld.so.conf and add the line

   /usr/lib/jvm/java-6-sun/jre/lib/i386/server

   or

   /usr/lib/jvm/java-6-sun/jre/lib/amd64/server for 64 bit installations
   

2. Run the command sudo ldconfig.

After that follow the comments #16 and #17:

1. Edit the file ~/.kde/share/config/nepomukserverrc and search the line

   Used Soprano Backend=redland

   In the [main Settings] section.

2. Change this line to:

   Used Soprano Backend=sesame2
   

And finally restart the Nepomuk server:

1. Using KRunner (Alt + F2) launch the command

   killall nepomukserver

2. And then restart the program nepomukserver with KRunner.

KRunner is nicely integrated with the desktop search.
