Reinstate System Menu after reverting to Gnome Classic?
Solution 1:
Sorry, the system menu cannot be brought back. You can get the shortcuts by enabling the "Other" menu. See http://ubuntugenius.wordpress.com/2011/10/17/ubuntu-11-10-upgrade-missing-your-system-menu-preferences-administration-launchers/ .
Solution 2:
I never found any native method to do so either.. So instead i installed cairo (cairo-dock) and when installed i find the same old classic menu by clicking the icon with the ubuntu logo. And this contains the System and Administration menus as well..
hoping this help you !
