Title:
  Can't unlock screen if VirtualBox runs in full screen mode

Status in “unity” package in Ubuntu:
  New

Bug description:
  Ubuntu version data:
     Description:	Ubuntu 14.04 LTS
     Release:	14.04

  Unity package data:

  unity:
    Instalados: 7.2.0+14.04.20140423-0ubuntu1.2
    Candidato:  7.2.0+14.04.20140423-0ubuntu1.2

  Hello,

  I'm running a full updated Ubuntu 14.04 and I've found a problem with
  the new lock screen (which is otherwise awesome):

  When VirtualBox is running in full screen mode, and the screen locks
  (e.g. i'm away from the computer for a while), I'm first unable to
  write in the password box in the lock screen, even if the input seems
  to be focused and the writing caret (I mean, the blinking | ) appears
  in the input field.

  Anything I type in the password box is sent to the VirtualBox's guest
  OS currently excecuting program, which in my case is usually
  VisualStudio (I see the password I typed in the currently opened file
  in VS, as all input is captured by VirtualBox it seems).

  To be able to unlock, I need to press RightCtrl + F (which is
  VirtualBox shortcut for toggling full screen mode) and then I can type
  in the password input box.

  So, although I can use the mouse in the lock screen (as I'm able to
  click to set the focus in the password box and use the indicators
  there), it seems that all keyboard input is still captured by
  VirtualBox.

  I haven't tested the lock screen with other full screen applications
  (such as games) but if you think it's important I'm willing to help
  testing that.

  I think it's a security vulnerability (so I'm marking the check) as
  the typed password is visible "as typed" in the active application in
  the guest operating system.

  Best regards.
