Como conseguir que o segundo monitor funcione ao lado da exibição principal?

Question

Eu quase tenho este problema resolvido ... Eu tenho os dois monitores trabalhando agora. A exibição secundária está exibindo um fundo roxo. Infelizmente, não posso usá-lo. (Eu não posso mover o mouse para ele, etc.)

Aqui está a saída de xrandr --verbose --screen 1 :

Atualização: depois de adicionar ...

  

Xinerama "1"

... agora tenho a tela secundária espelhando a principal. Mas espero poder ter exibições separadas.

    

Answer 1

Eu consertei. O problema é que, para usar o Xinerama, os dois monitores devem usar a mesma profundidade de bits. (16 bits)
