Bug description:
  [Impact]

  Some windows will grab the keyboard/mouse and when the lockscreen
  kicks in, this window will still have the grab and thusly, ou can
  enter your password in the lockscreen.

  [Test case]

  1. Open a window that will hold the grab, such as the ssh password dialog.
  2. Wait for the lock screen to activate.
  3. Enter your password to unlock the screen.

  [Regression potential]

  This particular fix doesn't fix all cases, but does fix it for some.
  That said, no new regressions are expected.

  trusty-sru-2.debdiff *

  Original Description:

  My screen just timed out and locked when a password prompt which had a
  grab was displaying.

  I couldn't type my password or interact with the indicators.

  gnome-screensaver just refuses to lock in this situation, perhaps
  unity could do the same unless it's possible to remove and readd the
  grabs yourself, but I don't think XLib lets you do that (you can only
  remove your own grabs AFAIK).

  TEMPORARY WORKAROUND TO LOGIN AGAIN:
  Click on the guest session
  Once the guest session is started log out
  This takes you back to the lightdm session screen you can then login to your user session and it be in the same state
