I just upgraded to 12.04. Now I get two icons in the lower gnome panel for every application that's open. I am using gnome without effects. The problem started when I switched from a two monitor configuration to a single monitor configuration. ( I disabled the internal graphic output of my laptop with the nvidia-settings program )
