Title:
screen cannot be turned back on after being switched off after some

Bug description:
I did a fresh install of ubuntu 16.04 on my old dell computer in which
there is an ati radeon X1300 graphics card.
Whenever the screen turns off due to inactivity, it cannot be woken
up by moving the mouse or by hitting a key.
The same ubuntu 16.04 installed on a laptop with intel graphics card
doesn't show this problem, so I first guessed it was related to the
radeon driver. But as there is no problem waking the screen when I
type "xset -display :0.0 dpms force off" in a terminal, it looks like
the radeon driver is not the culprit.
Oddly enough, invoking :
gnome-screensaver-command -a
in a terminal turns my screen off and after typing this line, the screen can
be woken up by moving the mouse or by hitting a key. I'm confused. It seems not
related to gnome-screensaver, but rather to the way ubuntu turns the screen off.
