I encountered the same thing after I upgraded, but the solution for me was actually quite simple.
Go to System > Administration > Login Window and type your password at the prompt. (alternatively, you could do a 'sudo gdmsetup' in the terminal) In the Local tab, you will probably find that under the Menu Bar section, the "Show Actions Menu" option is not checked. Check it, as well as "Include Hostname Chooser..." below it. Clicking your shutdown button in the upper right corner should now include the reboot and shut down options. -- No reboot/no shutdown after upgrade https://launchpad.net/bugs/30499 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
