i965 stack desktop non cec hdmi monitor timed turn off

[CaptainBlood]

xcreensaver achieves screen blanking, where backlight remains on.
I'm wondering if non cec monitor turn off is achievable...

enable screensaver:
xset s <screensaver delay in seconds>
replace screensaver with screen blanking:
xset s blank

enable explicit power management
xset dpms <standby delay in seconds> [ suspend delay in seconds [ power off delay in seconds ] ]

If screen blanking is not enough for you (it does make my display switch off), try that part with dpms.
