skjermoppløsning/oppdaterings frekvens ?

Postby Tmo on 07 Nov 2006, 18:16

Heyas.
Har nettopp installert Fedora Core 5, og plages litt med skjermoppløsning. (flimmer, og piping..) Noen råd for hvordan jeg får satt dette rett?
Brukernivået mitt med Linux ligger på totalt nybegynner nivå.

Skjermen jeg har er en Di-Fusion E900 (CM1997FS), skjermkortet et Gainward 6600 GT.
Ifølge Fecoras brukermenyer, skal skjermen stå i 1024x768 på 85Hz, Administrasjons-menyen mener skjermen skal være 1280x1024.. men det ser mer ut som 1024x768 på 60Hz for mine øyne.

Skjermdata fra leverandør:
Dot Pitch
0.26mm

Resolutions
1600 x 1200 @ 75Hz
1280 x 1024 @ 85Hz
1024 x 768 @ 115Hz
800 x 600 @ 145Hz
Frequency Range
Horizontal: 30kHz - 97kHz
Vertical: 50Hz - 150Hz
Video Bandwidth
180mHz

Skjermen klarer fint andre oppløsninger enn dette, tror det her kanskje er maks oppsløsning for de ulike frekvensvalgene.

Kan du leite fram filen /etc/X11/xorg.conf, og finne den "Section" som heter "Monitor". Deretter kopierer du hele innholdet av den seksjonen inn her på forumet.

HorizSync og VertRefresh er endret fra hvordan de sto "orginalt". (kopi tatt etter reboot, så burde være gjeldende...)

Det så jo fryktelig riktig ut, konfigurasjonsmessig da, i forhold til 1280x1024.

Du kan ta å kommentere ut HorizSync, VertRefresh og DisplaySize for å se om den klarer å autokonfigurere bedre. Hvis problemene fortsetter, så skulle jeg likt å se X-log-filen. Den ligger som regel som /var/log/Xorg.0.log

Stemmer... det er noe muffens med at den ikke finner "1280x1024" :)

Jeg så nå at i config-filen din at du bruker VESA-driveren. Prøv å bytt ut den med "nv"
