After I've installed openCV and after updating/upgrading apt-get, gnome crashed.

I was wondering how can I fix/reinstall/repair gnome.

best regards

You should be able to use this,

sudo apt-get install --reinstall gnome-shell

If not, then I would try

sudo apt-get install --reinstall ubuntu-desktop
