Comment 11 for bug 335730

Thanks for the advice - that worked only partially.
I had tried the command "gnome-panel" and thereby I got some menus back and could call the desktop-switcher applicatioon but it did not fully restore the UNR interface. e.g. the Ubuntu icon in the upper leftmost part of the screen was missing and applications didn't show the application bar.
 In the end I have resorted to a clean install from my usb-stick - that works and I'm not going to try to call the desktop-switcher again soon!

regards
