Por alguma razão, não consigo usar o Unity3D com o seguinte arquivo xorg.conf:

No momento, se eu escolhi o Unity3D, ele será exibido em uma tela, se eu escolher Unity2D, ele espelhará uma tela em todas as telas, então eu tenho que recorrer ao gnome-classic para obter todas as 4 telas para trabalhar o xorg.conf acima.
Após mais testes, tenho fontes que o Unity3D funciona se eu tiver apenas 1 ou 2 monitores conectados a uma única placa gráfica. Se eu conectar um único monitor a cada placa gráfica, o Unity3D não funcionará, ele cairá para o Unity2D. Se eu conectar 3 monitores, ou seja, 2 monitores no cartão 1 e 1 monitor no cartão 2, ele cairá para Unity2D. Se eu conectar 2 monitores a cada cartão, ele novamente cai para Unity2D.
Parece que o Unity3D só funciona com uma única placa gráfica ...
Como isso pode ser corrigido?
