I also have this bug. I use KAlarm and my computer with Ubuntu 12.04 (Gnome desktop) took several minutes to shutdown.
Link http://ubuntuforums.org/showthread.php?t=1764048 gave me the hint how to solve this problem. This link contains methods to prevent te starting up of nepomuk and akonadi in 3 steps. If you don't want to use KAlarm, it might be safe to apply all three steps. However, doing so, KAlarm could not be used. It asked to start-up akonadi first. So I tried what would happen if I only used the two steps preventing the (complete) start-up of nepomuk, and that worked great. KAlarm works and Ubuntu 12.04 shuts down within a few seconds. The steps to apply are: 1. Add the following lines to ~/.kde/share/config/nepomukserverrc (and their sections if they don't exist) (change the value from "true" to "false" if they do exist and are set on "true"; [Basic Settings] Start Nepomuk=false [Service-nepomukmigration1] autostart=false [Service-nepomukstrigiservice] autostart=false 2. Remove the file /usr/share/autostart/nepomukcontroller.desktop, if it exists. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1053783 Title: Ubuntu 12.04 - Stalled shutdown after having had KAlarm opened; with package info.
