Få 3 skärmar fungera med nvida-kort i SLI

[walle]

Jag har precis skaffat mig en tredje skärm som har kopplats in i min stationära dator som har bland annat två Nivida 580 i SLI. En skärm är kopplat till mitt första Nvidia-kort och två skärmar till den andra.

Problemet som jag får är att skärmarna till det andra kortet visar bara en vit bild när jag loggar in i Ubuntu. Drar jag musen över en av skärmarna fungerar muspekaren utan problem, förutom det faktum att jag bara får ett svart kryss än en vanlig pekare. Dock kan jag inte dra in gönder eller öppna fönser i något av dem.

Jag provade ta en printscreen, men den tar bara bild på den fungerande skärmen. När jag hade två skärmar så tog den en bild så om jag hade en långsmal skärm.

I bilagan kan ni kolla hur det ser ut.

Tack på förhand!

Jag glömde posta det jag hade i /etc/X11/xorg.conf:
