title: Ubuntu 14.04 on VirtualBox needs Guest Additions but resolution is too small to open a terminal.
body: <p>I have installed Ubuntu 14.04 on a VirtualBox running on a Windows host. The resolution is stuck at 640x480. I have found many solutions suggesting that Guest Additions is needed to resolve this issue, but at the current resolution, there appears to be no way to open a terminal to run apt. </p>
  
  <p>Suggestions?</p>
