Ok, i resolved this, but the problem is that I can control, the flicker and resolution of the external monitor. The image is always off-set and trembling... but I have faith on you. Is it a bug or just a bad configuration? I tried xorg.conf but I'm afraid it just doest't pay attention to the resolutions and refresh / sync values I define.
