Using Dual View ( Display of Notebook and external Monitor) Gnome 3.0 duplicates Menu
i am using Ubuntu 12.04 LTS at the moment with gnome3. It is running on an Fujitsu Celsius H Series.
I use this computer at the office and i have problems with dualview. When i dock my computer to the docking station, i want to bring the desktop to the external Monitor. It is connected by a DVI Cable. After i dock the laptop and start the machine, the laptop is closed in this moment, the login screen is only shown on the laptop panel. The Menu entries are after login duplicated. It does not matter, every time i make a new login, the menu entries will be one more than before.
I searched some forums and on ubuntuusers.de forum i found an entry which describes the same problem.
My only solution at the moment is, deleting the database entry in /home/username/.dconf/config/user and start a new login. But i have to undock my computer. Now i work without docking it on.
Is there anyone who is having the same problem? Any ideas how to solve this so that i can use a docked laptop and my external monitor?
