Isso pode ser relevante - notei que a saída xrandr está perdendo completamente as informações sobre outras saídas, mesmo a que está atualmente configurada?
Eu tenho a configuração de monitor triplo, com dois adaptadores gráficos da Nvidia. Eu queria configurá-lo da mesma forma como é configurado quando eu executo o Ubuntu no VMware - por exemplo, cada tela permite maximizar separadamente um aplicativo. No momento, só consigo configurar as telas para que fiquem todas brancas e, quando eu movo o cursor, ele muda para uma cruz preta. Abaixo está minha configuração - há apenas uma única tela por adaptador está configurada agora (para acertar o problema - no adaptador único com dois monitores eu sou capaz de habilitar Twinview, mas não é o que estou procurando). Eu sei que o Ubuntu está completamente bem trabalhando com 3 telas, porque eu tenho em execução na VM na mesma configuração. Eu só não sei como fazê-lo funcionar em hw real. Por favor, ajude, eu não quero rodar o Windows + VM apenas para rodar o Ubuntu com múltiplas telas.
