[opensuse-kde] How to start Akonadi?

Hi, I would like to test the Akonadi in KDE 4.2 in openSUSE, but I was unable to start it. In Akonadi configuration module I have a /usr/sbin/mysqld in a path, but I've got an error during start. There're a lot of 'InnoDB: Check that you do not already have another mysqld process' errors, but I've no mysqld process running (except the one from Akonadi). Has anyone some experiences with Akonadi? Best regards Michal Vyskocil
