I wrestled with the problem this morning, and here is the script I came
up with for notify-send on Debian 5 LTSP:
"""
#!/bin/bash
n=$(($#-2))
for user in `users |xargs -n 1 echo|uniq`; do
pid=`pgrep -u $user metacity`
DISPLAY=`grep -z DISPLAY /proc/$pid/environ| sed -e 's/DISPLAY=//'`
DBUS_SESSION_BUS_ADDRESS=`grep -z DBUS_SESSION_BUS_ADDRESS \
/proc/$pid/environ | sed -e 's/DBUS_SESSION_BUS_ADDRESS=//'`
export DISPLAY
XAUTHORITY=/home/$user/.Xauthority
export XAUTHORITY
export DBUS_SESSION_BUS_ADDRESS
sudo -u $user notify-send ${@:1:$n} "${@:(-2):1}" "${@:(-1):1}"
done
"""
Hope this is of use to other people!
