Dotaz: Belinea 102035W + Nvidia Geforce FX 5200

[Maly Pista]

Ahoj, mam problem s nativnym rozlisenim u monitoru Belinea 102035W v kombinacii s grafikou Nvidia Geforce FX 5200 (od Asusu). Monitor je pripojeny cez DVI, VGA na grafike nieje.

Najprv udaje o monitore: 31-83KHz, 56-75Hz, 160Mhz max, nativne 1680x1050@60Hz.

Distribucia: Ubuntu 5.10 + ovladace nvidia

Podstatna cast xorg.conf

A co sa mi nepaci v Xorg.0.log:

(II) NVIDIA(0): NVIDIA GPU detected as: GeForce FX 5200
(--) NVIDIA(0): VideoBIOS: 04.34.20.87.00
(--) NVIDIA(0): Interlaced video modes are supported on this GPU

(II) NVIDIA(0): Clock range:  12.00 to 135.00 MHz

So 135 MHz sa ani 1600x1200 ani 1650x1050 rozbehat bohuzial neda. Pridavat modeline nema zmysel, vsetky rozumne su v intervale 145-155Mhz. Pridanie

Option	"NODDC"      "1"

do xorg.conf tiez nepomaha nema na vysledok ziaden efekt.

S ovladacom "nv" som uspech tiez nemal, tu je cast (asi aj s dovodom) Xorg.0.log:

(II) NV(0): Clock range:  12.00 to 350.00 MHz
(II) NV(0): Mode "1680x1050@60" is larger than BIOS programmed panel size of 1280 x 1024.  Removing.

Vobec netusim, co je BIOS programmed panel size a ci sa da zmenit.

Zaujimave je, ze pokial bol monitor napojeny cez VGA na grafike i845 (driver "i810"), DDC udavalo maximum pixelclock 150Mhz. Grafika vsak 1680x1050 nezvladla.

Vobec tomu nerozumiem. Na googli ani na ubuntuforums som sa ziadne podstatne informacie nedozvedel. Prosim o akekolvek tip-y.

Ahoj, problem sa mi podarilo vyriesit uz skor, ale chcem sa podelit o riesenie, mozno niekomu pomoze. Dlhym skumanim (vzhladom nato, ze zatial s linuxom valne skusenosti nemam) som nasiel problem: paradoxne nim su najnovsie binarne ovladace od nVIDIe. V ovladacoch je od urcitej verzie implementovany pixelclock limit pre (single link) DVI kable. V prvych verziach po zavedeni je implementovany s chybou, neskor s umelym znizenim o niekolko mHz. Tento limit nedovoluje nakonfigurovat monitor a grafiku tak, aby fungovali ako maju. (Staci porovnat fekvenciu v modeline dole a vypis z Xorg.0.log hore a je to zrejme.) Prvotna informacia o probleme zom zohnal odtialto, zaroven je v tejto diskusii aj tip na riesenie - downgrade na verziu 7174, co je v Ubuntu 5.10 "legacy" verzia, ktora je k dizpozicii na installacnom cd. Presny postup downgrade je mozne najst aj na strankach ubuntufora. Po downgrade uz len treba nastavit prislusny Modeline a Option "ExactModeTimingsDVI" "true" (spomina sa v prvom odkaze) v sekcii Driver vo vasom xorg.conf, a je to.

Pre istotu relevantna cast xorg.conf:

Snad to niekomu pomoze. Inak, monitor je super, odporucam ako lowend 20" widescreen.
