[20:23] <touil76> I'm a user of ubuntu 16.04 not gnome edition, but I have an issue which seems really gnome related.
[20:24] <touil76> When the screensaver turns the screen off, the screen cannot be waken up again.
[20:25] <touil76> When I turn off the screen manually with : xset -display :0.0 dpms force off, the screen can be waken back up.
[20:25] <touil76> When I use xscreensaver instead of gnome-screen saver, there is no problem when the screen goes off. It can come back on moving the mouse.
