System Reboot/Suspend/Shutdown Menu Changed. How do I Repair

view story

http://www.linuxquestions.org – I have just installed Wheezy i386 with the Gnome 3.x display manager on my machine. While installing LibraOffice 4.x, the shutdown menu changed. It used to give me options like Shutdown, Suspend, Reboot, etc ... . Now I can only suspend or log out. How do I get the other options back. Suspend seems to shut everything down, but when I restart, it always comes back to the way it was before the suspension, which is not always what I need it to do. Thank you in advance. bruceam.
