I just found that typing :
gnome-screensaver-command -a
turns my screen off. But the funny fact is that, after typing this line, the
screen can be woken up by moving the mouse or hitting a key. I'm confused. It
maybe not related to gnome-screensaver after all, but rather to the way ubuntu
turns the screen off.

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

Bug description:
I did a fresh install off ubuntu 16.04 on my old dell computer in
which there is an ati radeon X1300 graphics card.
Whenever the screen goes off due to inactivity, it cannot be woken up
by moving the mouse or hit 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, I think the
problem is rather related to gnome-screensaver.
