[patch] Lock screen before suspend to prevent information leak

[Roland Lezuo <roland lezuo chello at>]

Hi,

the problem: after a resume from suspend for a short period of time the
content of the desktop appears on the screen before the lock screen is
activated (System Settings -> Brightness & Lock -> Require password ...
is activated).

This is not only visually annoying but may also leak information.

On my system the following trivial patch solves the problem.
(Does not test whether screen should be lock at all, though)

best regards
Roland Lezuo
