Configuração do Xorg para monitor adicional

Question

Eu tenho lutado para fazer uma terceira tela funcionar, que parou depois de mudar o monitor (anteriormente isso funcionava no USB displayLink). Eu tive erros de EDID na inicialização então agora gerou meu próprio arquivo xorg.conf como abaixo. A tela começa agora, mas mostra uma tela de carregamento do ubuntu informando 'Started Light Display Manager', mas não é reconhecida nas configurações da tela.

Answer 1

Eu acho que o ubuntu ignora xorg.conf. Você pode colocar essas coisas em /usr/share/X11/xorg.conf.d , mas provavelmente é melhor usar xrandr ou arandr ou unity-control-center para configurar seus monitores.
