I'm using VM VirtualBox 4.3.18 to run Ubuntu. It works fine, just that a few days ago I started seeing the screen of Ubuntu smaller (previous to that it was on full screen, and I can't recall changing anything). How can I fit it back to full screen?
Note: When I say 'full screen' I don't mean that I don't want to see the VirtualBox's task bar, so CTRL+F is not the solution I'm looking for (with CTRL+F my screen stayed small) . CTRL+C doesn't seem to work either; it gives me a screen in the desired size, but it's distorted.
