After the update of xorg into 1.16.0-2, screen is not turned off by DPMS in GNOME.
I also tried an manual command:
$ xset dpms force off
but it's not working.
In other WM, this command is working.
With xorg 1.15.2 and gnome 3, there is not this problem.
When I entered the command, the screen turned off for a couple of seconds and turned back on.

Updating xf86-video-intel to 2.99.912-4 solved the problem.
