Remove Appmenu (Global Menu) In Ubuntu 11.10

The appmenu (also known as the global menu) in Ubuntu Oneiric can be both a useful and annoying feature. When it is in action, it reduces the screen space required to render the menu bar. If you are using a computer with small screen, this is very useful for you. On the other hand, if you have a large screen, having to move your mouse to the top left corner of the screen every time you want to access the menu can be a troublesome chores.

• For those who wish to remove the appmenu, simply remove the appmenu app with the following command:

sudo apt-get autoremove appmenu-gtk appmenu-gtk3 appmenu-qt

Restart the PC. Your menu bar should stick to the top of your application window now.
Firefox

• If you are using Firefox, you will notice the above method will not work. This is because Oneiric is using a Firefox extension to enable the global menu effect.

1. In your Firefox, go to “Tools -> Add-ons -> Extensions”. Disable the “Global Menu Bar Integration” extension (You can’t un-install it).

2. Restart Firefox. The Firefox menu bar should stick to the application window now.
Re-enable Appmenu

• To re-enable the appmenu, all you have to do is to re-install the appmenu packages.

sudo apt-get install appmenu-gtk appmenu-gtk3 appmenu-qt

and restart your computer.
