I suddenly encountered a problem the other day where my top menu completely disappeared.

I could not figure out how to restore it but then I managed to get it back by loading up CompizConfig Settings and de-selecting "Enable Ubuntu Unity Plugin".

However, this then removes the Unity panel on the left.

My question is, how can I get both working again at the same time?

I have tried a few attempts at fixing this including resetting Unity but it doesn't fix this. I am thinking it might be a conflict thing, there was a pop-up asking me if I wanted to resolve conflicts when I first enabled the Unity plugin, but that doesn't seem to fix it. I have tried looking at other threads but they don't seem to be addressing the same concern as me. I temporally got them both working when I tried resetting the gnome-panel (from this post: how to reset gnome panel? )

dconf reset -f /org/gnome/gnome-panel/

killall gnome-panel

then typing in

gnome-panel

It works temporarily as when I restart or close the terminal the problem is the same again.

Here is the output of the command "gnome-panel":

gregory@gregory-HP-Pavilion-dm4-Notebook-PC:~$ gnome-panel

I am running Ubuntu 13.10.

Any help will be much appreciated.

Thank you
