If you blacklist the vboxvideo driver, you lose the full-screen and the hardware acceleration. You forgot to mention that. I recommend pressing RIGHT SHIFT and get into GRUB menu, choose kernel 4.12 and then install synaptic, uninstall kernel 4.13 and lock version 4.12 until this is resolved. This bug appeared today around here. It's a bug in the kernel.
