"Big Desktop" med ATI-drivere

AudunSæther · 18. februar 2005

Hepp.

Anskaffet en likedan skjerm som jeg har fra før, og prøver å sette opp et såkalt "Big Desktop" via fglrxconfig. Når X starter fungerer den ene skjermen (som er koblet til VGA-utgangen) som vanlig (altså skjermen til venstre), og skrivebordet er så stort som det skal være (om jeg maksimerer et vindu ser jeg altså bare halvparten her). Den andre skjermen (som er koblet i DVI-utgangen, med en DVI->VGA overgang, om det har noe å si) er derimot helt svart. Den er ikke av, eller i noe "standby-mode", det lyser akkurat slik det skal gjøre. Men altså ikke noe bilde.

X-config'en;

Noen som kan hjelpe meg her ?

Trur nok at Big Desktop ikkje fungerar skikkeleg for mange endå. Big Desktop suger på ATi-drivarane uansett. Xinerama-emulering hadde vore best.

Uansett, spør her, der dei har peiling:

Okey, skal se der. Hva er forskjellen på Big Desktop og xinerama ?

EDIT: glem det, jeg kan vel RTFM

Kan godt forklare det eg:

Big Desktop er kva det betyr, ein einaste stor desktop. Vindaugsbehandlaren du bruker (KDE/GNOME/Anna) ser dei 2 skjermane som ein einaste stor skjerm. Det er ikkje satt opp 2 skjermar og screens i xorg.conf, men Big Desktop vert definert i ATi-drivarens options.

Om du har vore borti fleire skjermar i Windows, er Xinerama mykje det same. F.eks om du maksimerar eit vindauge på den eine skjermen, vert vindauget kun maksimert på den skjermen. Med Big Desktop vert vindauge over begge skjermane, og mange ting kjem midt i mellom skjermane.

Det som er bra med Big Desktop i motsetning til Xinerama er at BD bruker GPU (skjermkortets prosessor), mens Xinerama belastar CPU.

NVIDIA har eit flott system for Xinerama gjennom GPU.

AudunSæther · 18. februar 2005

Okey, da har jeg fått litt innsikt.. Har sett litt på Dualhead også. Har jeg forstått det slik at det da kjøres to helt forskjellige X-servere? Hvordan får jeg startet den andre serveren med en vm ?

Tror jeg skal sette ett NVIDIA-kort litt høyere på prioriteringslisten

LessThanJake · 18. februar 2005

Hvis du har to X-servere startet vil du ikke kunne flytte musen fra den ene til den andre helt uten videre. Hvis du ikke har behov for 3d-ytelse, på begge skjermer fungerer xinerama glimrene.
