Have a peculiar problem on my laptop. It "lost" its Shutdown button on
the Shutdown menu. All the others are there (hibernate, restart, etc),
respaced to fit the lack of a Shutdown icon. I've been forcing a close
with Ctrl-Alt-F1, logging in, then "sudo shutdown -h now," but that gets
old. How did I lose it and/or (more importantly) how can I get it back?
I uninstalled the applet from the toolbar and reinstalled, but it came
back without the Shutdown button. What's going on?
