More info, please. What resolution are you getting? What resolution are you expecting? Are you trying to run one monitor or two? You seem to have a DVI port and a VGA port, correct? The DVI port is saying it can't find a valid EDID, the VGA port appears to find a valid EDID. I would normally take this to mean you have two monitors, the VGA one is working fine but the DVI one isn't. Is that correct?

Do you have an /etc/X11/xorg.conf file? Or any files under /etc/X11/xorg.conf.d/ ?
