#Background I'm trying to restart some programs (mail-notification and stalonetray) regularly, as they appear to die frequently. I want to set restart them whenever NetworkManager reconnects. Hence, I have them triggered by a script in /etc/NetworkManager/dispatcher.d/.

#Scripting I can create a script as follows.

#!/bin/bash
sudo -u foo_user pkill mail-notificati -x
sudo -u foo_user DISPLAY=:0 mail-notification &

This works fine if I run it directly as a user. However, if I call it from root's script, it fails. I am prompted to enter the passwords for mail-notification; it cannot read Gnome Keyring.

How can I run this program as foo_user in every way?
