title: Unable to use virtual Box on full screen
body: <p>First of all, I'm using Virtual Box 4.1.4 to emulate Xubuntu 14.05.5 on a windows 7 computer.</p>
  
  <p>I have some trouble to emulate Xubuntu in full screen on my VirtualBox, I tried a lot of solution i found on the internet, but none of them seems to work on my case.
  On first, i tried to install it from the guest addition module, but i had this error : </p>

  <p>Then i tried to install virtualbox guest-x11 but it doesn't seem to change anything neither...
  I'm kinda stuck right now, and I hope some of you could have a solution...</p>
  
  <p>Thanks for all !</p>
