Não típico do miltimonitor xorg.conf - 2 GPUs (nvidia) e 5 monitores

Question

Eu instalei algum tempo atrás elementary OS Freya. Eu estou lutando por um par de dias para obter a configuração correta para o meu não típico conjunto multimonitor

2 placas gráficas nvidia GeForce GTX 660 Ti & amp; GeForce 9800 GT

01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT] (rev a2)

5 monitores: DELL 2407WFP (retrato), HP LP2465 (retrato) à esquerda, Samsung SyncMaster 305T (paisagem) no centro, HP LP2465 (retrato), HP LP2465 (retrato) à direita. 2 da esquerda e do centro um estão conectados à GeForce GTX 660 Ti, dois à direita estão conectados à GeForce 9800 GT.

No nvidia, o autoconf apenas monitora à esquerda e o centro um, mas dois à direita estão escuros ... Eu posso mover o cursor sobre eles, mas nada mais. Eu percebi que desta forma eu não recebo nada.

Agora mesmo estou trabalhando no xorg.conf para essa configuração. Eu estava procurando por uma configuração semelhante e me deparei com esse . Eu uso um pouco para fazer o meu, mas não tenho certeza se está tudo bem. Eu agradeceria muito se você gentilmente me desse alguma ajuda nesta configuração.

Answer 1

A Nvidia tem uma nota de aplicação descrevendo usando (2) cartões Quadro com 4 monitores. Eu tenho uma configuração de trabalho com um único quadro e 4 monitores, usando a opção somente MetaModes.

Option         "MetaModes" "1920x1080 +0+0, 1920x1080 +1920+0, 1920x1080 +0+1080, 1920x1080 +1920+1080"
