I want to run it through cron every 30 minutes. When I run the script from the command line, it works perfectly. When I run it through cron, it doesn't work. The command in the script is: /usr/bin/gconftool -t str --set /desktop/gnome/background/picture_filename '#{new_picture}' Please accept the the variable new_picture is properly set. I create a trace file in the script and have verified that it is correct. The relevant error that I'm seeing in /var/log/auth.log is dbus-daemon: Rejected send message, 1 matched rules; type="method_call", sender=":1.53" (uid=1000 pid=12008 comm="/usr/lib/indicator-applet/indicator-applet --oaf-a") interface="org.freedesktop.DBus.Properties" member="Get" error name="(unset)" requested_reply=0 destination=":1.84" (uid=0 pid=13817 comm="/USR/SBIN/CRON ")) I know enough to find the message, but I don't have a clue how to proceed to fix this. This script works perfectly when invoked from the command line and doesn't work when called through cron (my userid - not root). I'm on jaunty. Any and all help greatly appreciated. ---Michael </body></html>
