Eu tenho dois Geforce GT1030, com 4 monitores. Eu estou tentando ativar todos os 4 de tal forma que eu possa usar cada um deles em uma exibição de monitor estendido.
Eu executei pdo sudo add-apt-repository ppa: graphics-drivers / ppa e nvidia-384.111, 390.25 e 387.34 selecionados, em qualquer evento no momento em que mudo: Opção "Xinerama" "0" de 0 a 1 e reinicie, a tela inicializa, eu recebo a tela roxa e depois fica preta. Preto como os monitores são a vida (eu posso ver o cursor), mas nenhuma sessão do Ubuntu ou tela de login.
Em 384.111, eu desativei Wayland completamente sob a configuração gdm3 para ver se de alguma forma isso era um problema, mas não parecia mudar nada (o driver nvidia parece que pode fazer isso por padrão?).
Abaixo está o meu xorg.conf para uma possível referência:
