To run the  LECTURNITY Player under a linux system is not as easy. Therefore, here is a short how-to which I tested on my Ubuntu 8.04 system.

1. Download the LECTURNITY Player
   http://www.lecturnity.de/download/lecturnity-player/ (Choose the Macintosh/Linux-Version)
2. Download the Java Media Framework API (JMF)
   http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/download.html
   (Choose “Linux” as platform,  agree the “License Agreement” and choose the “Cross-platform Java” (jmf-2_1_1e-alljava.zip)
3. Unzip the jmf-2_1_1e-alljava.zip
   unzip jmf-2_1_1e-alljava.zip
4. Create a lecturnity folder at /opt/
   sudo mkdir /opt/lecturnity
5. Move the LECTURNITY_Player.jar to /opt/lecturnity/
   sudo mv ./LECTURNITY_Player.jar /opt/lecturnity/
6. Move the JMF to /opt
   sudo mv ./LECTURNITY_Player.jar /opt/
7. Create an executable file
   sudo touch /opt/lecturnity/lecturnity
sudo chmod 755 /opt/lecturnity/lecturnity
8. Fill the file (Thanks to tiwoc.de)
   #!/bin/sh
java -cp /opt/JMF/lib/jmf.jar:/opt/lecturnity/LECTURNITY_Player.jar imc.epresenter.player.Manager
9. Create a link to the executable file
   sudo ln -s /opt/lecturnity/lecturnity /usr/local/bin/lecturnity
10. Refresh the bash
    source ~/.bashrc
11. Run the LECTURNITY Player
    lecturnity

Troubleshootings

1. “bash: /usr/local/bin/lecturnity: /bin/sh^M: Defekter Interpreter: No such file or directory”
   dos2unix /opt/lecturnity/lecturnity/opt/lecturnity/lecturnity
2. “Ein Font wurde nicht gefunden: XYZ Die Darstellung kann deshalb fehlerhaft sein”. In this case, you can install the windows fonts. Warning: This fonts will be also interpreted by the browsers, e.g. firefox.
   sudo apt-get install msttcorefonts (Since Ubuntu 9.04 ttf-mscorefonts-installer)
3. “Ein oder mehrere Videos konnten nicht geladen werden. javax.media.CannotRealizeException. Möglicherweise ist ein benötigter Video-Codec nicht installiert“. If the codec is installed, usually the video can be seen. If not, install the xvid codec
   sudo apt-get install libxvidcore4
