after upgrade from kde 4.3.x to 4.4.2 from kubuntu software updates, notification system changed back to normal and i couldn't find the option in system tray to enable ayatana notification.
anyone know how to enable the ayatana notification ?

In Kubuntu 10.04 the Ayatana-like notification patches were split off into a separate application/package, colibri.
I found a nice how-to here: http://kristofkiszel.wordpress.com/2010 ... ntu-10-04/
