disabled=$HOME/notify-osd-disabled
if [ -e $disabled ]
then
  sudo chmod +x /usr/lib/notify-osd/notify-osd
  rm -f $disabled
  # Unmute sound.
  # amixer -q -D pulse sset Master toggle
  echo "Enabled notify-osd" # and unmuted sound"
else
  sudo chmod -x /usr/lib/notify-osd/notify-osd
  killall notify-osd 2>/dev/null
  touch $disabled
  # Mute sound.
  # amixer -q -D pulse sset Master toggle
  echo "Disabled notify-osd" # and muted sound"
fi

It would be very nice if this could be implemented with a tray icon!
