The same problem appears to me after upgrading to 16.04 with an Intel
card (described below), both with sleep and deep sleep: when I wake the
computer, I have a normal box in the centre of the screen, the rest is
darker, and no login box...
My only turn around is to log on another TTY, and stop the session (kill
-9 -1).
Similar environment otherwise (16.04.01 up to date, amd64), except fr_FR and
graphic card.
`sudo lshw -C display` returns (in French) *-display
