    Screen goes black

    This already started to happen when I had 11.10 and I thought 12.04 will fix it but it's still the same. The problem is that if my laptop is idle for around 4 minutes my screen turns off even though my screensaver and power management are disabled. How can I fix that?

    Code:
    xset -q

        Try
        Code:
        xset s noblank
        Ok, got it: Ashes come from burning.

              Ive had problems with DPMS switching on and off by itself. Next time it happens, use xset-q to see if DPMS is enabled. If it is, do
              Code:
              xset -dpms

                solved my problem. I have HDMI output and had to move the mouse every 10 mins.
                I made bash script calling the two command:
                xset -dpms
                xset s noblank

                and so the screen does not go black anymore.
