Disable global menus in Linux (Ubuntu)

Here is a way to get the menus in Ubuntu to reside on application windows instead of the top bar:

Open a terminal window and enter:

sudo echo "export UBUNTU_MENUPROXY=0" > /etc/X11/Xsession.d/81ubuntumenuproxy

Next log out of the system and log in again and it should work. To re-enable it enter:

sudo rm /etc/X11/Xsession.d/81ubuntumenuproxy

Log out, and back in again.
