Monitores corretos não detectados em 16.04 Nvidia ou Nouveau

Question

Após a instalação do 16.04, um Dell 2408WFP não foi detectado pelo driver Nouveau padrão. Eu então instalei o driver da Nvidia esperando um resultado diferente, mas isso produziu o mesmo resultado.

Agora mudei de monitor novamente e ainda não está aparecendo. Esses monitores aparecem apenas como CRT-0 no painel de controle NVIDIA X Server Settings .

Alguma idéia do que eu posso fazer para forçar o X e os drivers da Nvidia a detectar o monitor apropriado que está conectado?

Aqui está uma cópia do meu Xorg.0.log para revisão.

Quando modifico xorg.conf com o seguinte:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"

    EndSubSection
EndSection

Eu infelizmente recebo o seguinte erro:

Could not apply the stored configuration for monitors

none of the selected modes were compatible with the possible modes:

Consegui resolver isso configurando manualmente meu próprio /etc/X11/xorg.conf :
