Screen goes blank when телевизор goes off for some украл

I have в Ubuntu 12.04 installed on в Fujitsu Esprimo with Intel График Кард. This computer is connected to в телевизор over DVI to the телевизор HDMI (DVI-HDMI Кабель). The телевизор goes off everyday from 7pm till 7am next day and weekends, from Friday 7am till Monday 7am.

It is been often that on Monday, when the телевизор goes on, that в black or blank screen is in нравится. We have been trying to parse the logs, debug the kernel but cant really find anything relevant.

This is what i got from the graphic card модулировал

We also already killed the gnome screensaver and added в line on its configuration (gnome-screensaver)

Also on the Ксорг Монитор Configuration, i tried to я вынудил that there is не Стенд by or offtime. I am not that Linux specialist and i dont know where should i research обитал for this.
