I certainly like notifications in 12.04, but depending on the work I do they can be quite distracting.

Is there an official way or a tweak to temporarily deactivate notifications?

UPDATE: To clearify, I am looking for a way to do that in Unity.

I don't believe there's an official way, but it's easy enough to disable in the terminal (for presentations, etc.):

  sudo chmod 000 /usr/lib/notify-osd/notify-osd
  killall notify-osd

Afterward, just chmod it back to 755 and notifications will resume.

You need root access to do this. That's not very practical. –  Marco Sep 7 '12 at 12:05

This is how I achieved it

Create a sh file called stopNotification.sh and paste this line

killall -s SIGSTOP notify-osd

Create another sh file and continueNotification.sh and paste following line

killall -s SIGCONT notify-osd

Then goto system settings > keyboard and assign a shortcut for it.

Simple :)
