A configuração do meu dock link / monitor multi funciona mal com os drivers da Nvidia, e gostaria de maximizar os recursos disponíveis na minha GPU durante a execução, por isso quero rodar programas CUDA enquanto deixo os chips Intel manipularem a renderização de gráficos. Eu tive sorte fazendo esse tipo de coisa no Windows, mas parece que o driver nVidia "não está funcionando" quando a Intel é a GPU ativa. Quando mudo de volta para a Nvidia não recebo erros.
