Many Ubuntu users, especially the ones who have recently shifted from Windows to Ubuntu, find the Global Menu as an irritating feature. This feature was introduced in Ubuntu with the introduction of Unity. The display of menu in the Gnome Panel was not a very appreciated thing of the Ubuntu environment. So if you are running an application, you will not find its menu in the same window but on the panel which is quite inconvenient. If you are an Ubuntu user and don’t like the Global Menu, here’s a trick for you to disable this feature in Ubuntu 11.10 Oneiric Ocelot.
Open the ‘Terminal’ of your Ubuntu OS and type up the following command:
sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt
Afterwards, restart your system for the changes to take effect.
There might also be a scenario where you might not like the changes and might want to go back to the original settings of the Global Menu, so don’t freak out this is a totally reversible process. Type the following command to get back your old settings:
sudo apt-get install appmenu-gtk3 appmenu-gtk appmenu-qt
