I updated my KDE 4 installation to KDE 4.2 couple of days ago, and everytime I restart, KDE and Akonadi would throw me an error about MySQL server not being installed. Akonadi is the suite in KDE 4.2 – and I don’t use it – and sure as hell don’t want to install a MySQL database server just for this. So I decided to get rid of Akonadi – just fire up your package manager and uninstall it. It would probably remove the entire KDE PIM package – but meh, I’m good with that.
Specifically in Sabayon, open the terminal, switch to root using
and hit enter.
equo remove akonadi
