title: Enabling GUI on Vagrant VirtualBox - undefined local variable
body: <p>I'm new to vagrant/homestead, and I'm trying to debug the box that was created using vagrant up as the connection is on a timeout loop.  I'm trying to enable the GUI.  I've tried adding the config from the vagrant site and every variation of it to my vagrantfile:</p>
  
  <pre><code>config.vm.provider "virtualbox" do |v|
    v.gui = true
  end
  </code></pre>
  
  <p>But whenever this is in there and I run vagrant up or reload, it just returns <code>"Message: undefined local variable or method 'config' for main:Object"</code></p>
  
  <p>Any ideas?  Thanks in advance!</p>
