Jeg har læst mig frem til, at det er normalt, at KVM switche stopper EDID signalet som fortæller X hvad skærmen kan klare. Jeg har derfor forsøgt manuelt at definere vertikal og horisontal frekvenser i xorg.conf samt slået EDID fra. Hidtil dog uden succes.
Jeg bruger et GTX275 Nvidia grafikkort med 195.30 driverne (havde det samme problem med 190.xx driverne).
Min xorg.conf ser p.t. sådan ud:

(II) do I need RAC? No, I don't.For mig ser det ud som om, at X ignorerer EDID som den skal, men alligevel ikke bruger de definerede horisontale og vertikale frekvenser.
Jeg har forsøgt at definere modelines online og via CVT og indsætte i screen og monitor sectionen. Jeg har dog endnu ikke fundet noget der viker. Sikkert mig der gør det forkert.
Min horisontal frekvens er 31-83 khzog vertikale 56-76hz. Dot clock 162 Mhz og maksimal opløsning 1920x1200.
Håber nogen kan hjælpe. Har fedtet med det et par dage men endnu uden held. Er efterhånden ret presset da det er min arbejdsstation der er nede.
På forhånd stort tak!
