Unintentionally while I was doing the upgrade ubuntu to the 16:04 version, hung up the computer and gave an error in the installation, I managed after many conflicts when installing managed.
My standard desktop that use is gnome-classic but for some reason the menu bar does not appear, tried reinstalling the packages and a lot of little things, like do not do idea what to do, I'm using the community.
The alt + f2 command is not working.
If anyone has any idea what to do please help me I.
I also tried this command to restore the compiz settings but also did not show the bar.
dconf reset -f /org/compiz/ setsid unity unity --reset-icons
