i use this script in cron to post MPD now playing to twitter every hour

#!/bin/bash export DISPLAY=":0.0" msg=$(mpc current -h 192.168.1.33) twitter set "#MPD Server nowplaying $msg : http://cirrus.turtil.net:9001" #ttytter -status="#MPD Server nowplaying $msg. http://cirrus.turtil.net:9001"

exit

similar script using notify-send

#!/bin/bash export DISPLAY=":0.0" notify-send -i ~/.icons/48arch.png 'OS- Archlinux x86_64 : DWM Window Manager' 'Installed on Sun Apr 21 2013 at 18:17:22' exit

you may be experiencing problems as KDE uses its own notify-deamon IIRC, good luck.
