I am not using any adapters, KVM, etc. I tried using each option (Option "IgnoreEDID" and Option "IgnoreDDC") with the default xorg.conf from the Live CD and no luck. The screen just kept flickering really bad. Unfortunately I am short on extra hardware and I don't use Windows but I will attempt to boot from the onboard video card and report those results soon. Also I removed the Option "PreferredMode" "1280x1024@85" from the my edited xorg.conf and the resolution is perfect. Please let me know if you need that xorg.conf and/or that Xorg.0.log. Thanks!
