I'm missing any sort of menu (top bar or bottom) when using Gnome in Ubuntu 11.10.  I'm not using Unity.  Gnome Classic has a menu at the top, but I can't stand it because it won't autohide, even with some gnome-shell-extension.  Gnome-tweak-tool won't even show any extensions in that tab.

I logged in under Gnome (not Gnome classic).  I opened up terminal from the desktop and ran gnome-panel, and sure enough it did come up... so it's not running gnome-panel automatically?  Also it still won't autohide even with the extension in /usr/share/gnome-shell/extensions :\
