I there! I'm a new Ubuntu user and I began with version 11.10. I recently installed Gnome Shell (gnome-shell package in Ubuntu Software Center) after running with Ubuntu 2D. I thought it would be faster but indeed not really (mainly) because (I guess) all the fancy visual effects. However, I really love the interface and so would like to keep running with GNOME Shell (not GNOME Classic).
How/Where can I disable all those fancy visual effects in order to work with the lightest interface I can?
