I had to shutdown my laptop unconventionally because of a programm error. Now if I startup I receive just the blue desktop wallpaper, without any menus. Can't even access the terminal. The right mouse button works and behaves normally and I can reach the settings. Something with gnome?
I already tried
sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo apt-get install unity
from the command line without any success.
I also tried:
sudo apt-get install --reinstall ubuntu-desktop
