Same here. I'm on Ubuntu GNOME Remix. Doesn't seem to matter whether I'm playing a video (totem, vlc, YouTube, whatever) in fullscreen or not fullscreen, whether the timer in Brightness and Lock setting is set to 10 min, 1 hour or Never... The screen always goes black after 10 minutes. Always. (Unless I move the mouse or type on the keyboard, of course.)
