just installed Emacs 24 on a ubuntu precise OS. The menu bar in the top panel is missing a number of options (e.g. using Auctex, all the Latex options).
I recall seeing on the web somewhere that it was possible to have the menu on top of the Emacs frame rather than the unity default of the top panel. There is an answer on SO for how to enable the global menubar in ubuntu. Can someone please point me to how to disable it in the global menu until it gets to the point where they play well together.
Thanks
Ubuntu has a hardcoded hack to disable the global menubar for applications matching certain filename patterns. emacs is among those, as is firefox, another popular program that suffers from the same sorts of problems of GTK detached menubars not updating in the usual way that X programs expect them to.
Try running update-alternatives to select emacs24 as your default Emacs, then use emacs to start it, rather than emacs24.
