Lav skærmopløsning efter installation af KVM switch
Jeg har netop installeret en Avocent KVM DVI Switch, så jeg kan køre min MAC og min PC på samme skræm/mus/tastatur. På MAC siden fungerer alt fint og på Windows7 på PC'en kører det også fint. På Ubuntu 9.10 (som er mit primære PC OS) får jeg dog maks en opløsning på 640x480 (normalen er 1920x1200).
Jeg har læst mig frem til, at det er normalt, at KVM switche stopper EDID signalet som fortæller X hvad skærmen maks 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.
Min xorg.conf ser p.t. sådan ud:

Jeg håber nogen kan hjælpe. Er ved at være lidt presset :-)

Re: Lav skærmopløsning efter installation af KVM switch
Prøv evt at kigge her:
http://ubuntuforums.org/showthread.php?t=83973
Burde virker på ikke ubuntu distroer også ville jeg mene.
--EDIT--
Det er depth og modes du skal kigge efter. Jeg tror nu ikke det er nødvendigt med den identifier som er lavet i eksemplet.

Gør dog ingen forskel. Her er et uddrag fra min Xorg.0.log hvor det ser ud som om, at jeg har defineret modeline forkert.

Kan være jeg skal fedte lidt mere med den (på den anden side: If it ain't broken - don't fix it), men nu kører jeg i hvert fald 1920x1200 :-D
