[Olug-list] Ny LCD-skjerm virker ikke på DVI

[Per Inge Oestmoen]

Hei og takk for sist!

Under det siste OLUG-møtet diskuterte undertegnede med Kenneth om det 
ikke nå var på tide å forsøke seg på en skikkelig LCD-skjerm, og 
konklusjonen ble en slik er kjekt å ha. For egen del var situasjonen den 
at min syv og et halvt år gamle CRT var blitt ganske sliten etterhvert, 
så jeg bestilte en slik:

http://www.komplett.no/k/ki.asp?action=info&p=37470&t=659&l=2&AvdID=1&CatID=23&GrpID=4&s=pl

Nå er problemet at jeg får den bare til å virke med analog 
VGA-tilkopling. Den kjører greit i 1280x1024, men skjermens fulle 
potensial blir selvfølgelig ikke tatt ut uten DVI. Hvis jeg kjører 
L557'en på DVI starter Linux som vanlig, men så snart jeg går inn i X, 
forsvinner bildet og alt blir mørkt. Kommandolinjen er grei, men når jeg 
kommer til X forsvinner signalet, og skjermen melder at:

fH: 38.5 kHz
fV: 0,0 Hz

Jeg har satt opp XF86Config slik som vist nedenfor. Hvordan skal det 
konfigureres slik at jeg kan bruke digitalinngangen (DVI) i stedet for 
analogt signal?

Det hører med til historien at dersom jeg setter denne skjermen på en 
boks som har et visst annet (unevnelig og utillatelig) operativsystem, 
kjører den glatt på DVI, men noe mer triksing er altså påkrevet under 
Linux.

Hva må jeg gjøre?
