Disable Notifications in Ubuntu 9.04 Jaunty Jackalope
Ubuntu 9.04 sports a new notification system called notify-osd which any application can use to alert you of changes. Although the notification overlays look pretty cool, they’re craving for your attention and could sometimes be very annoying and distracting.

You can turn off these notify-osd notifications by typing this single command in your terminal:
sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled
Restart your computer. They’re gone. Forever!
