Eu gostaria que o X usasse drivers do OSS ou apenas gráficos da Intel.

EDIT 11 de agosto:

Parece que uma em talvez vinte botas é bem sucedida. Estou no X agora, mas não me atrevo a reiniciar.

EDIT Ago 15:

Ok, eu consegui executar o X na Intel GPU - desinstalando bumblebee e adicionando nouveau.modeset=0 aos parâmetros do kernel. Mas eu ainda não sei como usar a GPU NVIDIA.
