You need to install the VirtualBox Guest Additions into Ubuntu. This gives a few benefits, including resizing the Ubuntu screen to match the host window.
Start the VM, then select from the VirtualBox menus:
Devices ⇒ CD/DVD Devices ⇒ VBoxGuestAdditions.iso
Then follow the instructions.

Seems obvious, but also keep in mind to change the resolution in the guest OS. – Aritz Apr 10 '18 at 10:02

1Under Virtualbox 6.0.4 on MacOS, the menu would be: Devices -> Insert Guest Additions CD image – Bon Feb 03 '19 at 12:30

In version 6.0 of Virtual Box the menu is Devices -> Insert Guest Additions CD image... then you will have to authenticate for the installtion to happen. – thanos.a Oct 29 '19 at 17:49

I encountered the same problem on my PC recently. This is my solution;
Go to the Ubuntu machine:
Settings ⇒ Display ⇒ Graphics controller ⇒ Choose (VBoxSVGA or VBoxSVGA)
My original settings which caused the problem was VMSVGA
.
This solution worked on my PC. I cannot guarantee that it will work on yours.
