xfce4.10, GUI Reboot/Suspend

[James Griffin]

Hi

I've read a number of older posts found on the internet about using the 
xfce4 menus to reboot and shutdown the system. Amounts to using options 
in xinitrc and a '.pkla' file in /usr/local/etc/polkit-1/localauthority.

All of the variations i've tried do not work as intended. Can someone 
using xfce4 on FreeBSD 10 explain how to do this, it shouldn't be so 
difficult (should it?).
