I'm running Gnome Shell (Gnome 3.4.2) on Ubuntu 12.04 (64 bit). I can't figure out why I can't change the Power setting so that the battery icon on the status bar will show. If I change the setting under Power settings for "Show battery status in the menu bar," the setting does not save: whenever I re-enter Power settings, the setting is still blank.

I'm not sure why this is. None of the Gnome extensions from extensions.gnome.org work either.

I can't seem to find anyone else on the Internet with this specific problem. Does anyone know what the problem is or how to fix it?
