Estou usando o Ubuntu 12.04 em um DELL XPS com o NVIDIA Optimus. Eu sei que perguntas relacionadas a isso foram feitas várias vezes, e eu segui muitos tutoriais e instruções, mas não consegui fazer isso funcionar.
Eu tentei instalar várias versões diferentes de drivers proprietários da NVIDIA (xswat, xorg edgers, download diretamente através do site, etc.) e nenhum funcionaria (o módulo NVIDIA nunca é carregado e nem consigo abrir as configurações da nvidia) .
Eu li que os drivers NVIDIA são incompatíveis com essa arquitetura híbrida, então eu não me importo se vou usar a placa NVIDIA ou Intel (eu não estou usando este laptop para jogos, não há necessidade de super gráficos), eu só quero que o segundo monitor funcione.
Eu também tentei alterar manualmente o arquivo xorg.conf, baseado em um exemplo de xorg.conf que eu encontrei aqui mas não funcionou, então retrocedi as alterações; Eu não sei se o problema é que eu não sei como configurar corretamente esse arquivo, ou não funcionaria independentemente da alteração feita. Remover o xorg.conf também não funciona (ou seja, o Ubuntu funciona normalmente, mas ainda não tem um segundo monitor).
Aqui estão as saídas do meu ambiente, por favor, deixe-me saber se você precisa de mais alguma coisa:
