Screen Size too Small in Ubuntu on Oracle VM VirtualBox

I just installed Ubuntu 15.04 in my Oracle Virtual VM and found that my screensize was set to 640×480 aka Too Small!

Needs to be bigger

There is a quick fix though. Run the following command, shut down the machine then restart it, and it should be fixed.

Much better!

If that fails, do make sure that you are using the latest version of Oracle VM VirtualBox by upgrading.
