Still cannot get it to work in Ubuntu. After entering this command in terminal: "sudo chmod u+s /sbin/shutdown" which should disable password prompting for the sudo shutdown command Ubuntu still won't shutdown. Any thoughts?

This review is for a previous version of the add-on (0.7).  This user has other reviews of this add-on.

"chmod u+s ..." doesn't disable password prompting for sudo. It sets the setuid bit in file permissions. This allows everybody to run the executable with the permissions of the file owner. Usually this isn't an good idea. You have to edit "/etc/sudoers" with visudo to allow specific users to execute "/sbin/shutdown" without an password prompt.
