I have activated gnome-flashback on 15.10 (wily). Since I switched from Unity to gnome-flashback the application menus (File, Edit, View, ...) are missing!
My actual workaround is to install indicator-appmenu-applet to have the menus in the upper panel.
How can I move the menus back to the application window?
Update: After testing a little bit longer I found another very strange workaround/behavior:
- open unity-tweak-tool
- killall nautilus
- select another theme in the unity-tweak-tool and switch back to Ambiance.
- open Nautilus. The menus are back! :-)
- logout and login again
- the menus are gone again! :-(
What's going on here?
