Yesterday I upgraded my version of Ubuntu. In stead of Gnome I now have the Unity environment. I'm not sure I like Unity better, so I'll give it a probation period to see if it's any good.

What I really do not like though, is the Global menu bar. After googling I found that I had to enter:

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

If I do that I get the error message:

E: Unable to locate package appmenu-gtk3

Can anyone tell me what I'm doing wrong here and explain how to fix this problem?

It already means that you don't have the appmenu-gtk3 package installed in your computer.

If you are not convinced, try removing something that you obviously know doesn't exist.

For example,

sudo apt-get remove kinglear 

would give the following error message:

E: Unable to locate package kinglear

Okay thanks, but it should be installed, or otherwise I should not have that global status bar. And if I want to install it, it still cannot find that package. (If I do apt-get install appmenu-gtk3 I get the same error message) So now my question is twofold: How do I uninstall the global menu bar, so that each window get's it's own menu. The other is: if ubuntu cannot find a package to install or uninstall how do I let it know where to find it? – dre Jun 17 '12 at 6:52

To remove the menu bar,

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

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

Also you could try removing it by using Synaptic Package Manager. If you need to install it

thanks for answering, but the problem is that if I enter that line in a shell I get an error message: "E: Unable to locate package appmenu-gtk3", so what am I doing wrong? – dre Jun 16 '12 at 20:20
@Mitch: the link from the logo does not "appear" in any browser (i.e. not clickable). Please fix when you get a chance... – izx Jun 18 '12 at 14:00

Yes, if it says there is no package as appmenu-gtk3, it is indeed the case. But you can disable global menu by following below procedure:

Go to /etc/X11/Xsession.d/ and open the files 80appmenu-gtk3 and 80-appmenu with administrative power.

command in terminal: sudo gedit /etc/X11/Xsession.d/80appmenu-gtk3 and comment out all the lines by putting a # mark before each line.

do this also for 80appmenu, by opening with sudo gedit /etc/X11/Xsession.d/80appmenu.

Logout and login again.
