Eu tenho um laptop com dois gpus (Intel HD4600, Nvidia GTX850M) que executa o Ubuntu junto com o Windows 10 (não tem problemas) usando o GRUB.
Instalei o nvidia-355 e não instalei o bumblebee devido a experiências ruins (nunca consegui funcionar / ele ou eu quebramos a instalação).
Algo relacionado à exibição / gráficos trava quando tenho carga gráfica pesada, e vejo uma parte das mensagens de inicialização piscar brevemente e estou na tela de login novamente.

Isso é repetido várias vezes por cem vezes.
Eu mexi com meu xorg.conf neste fim de semana, parecia assim antes:
Section "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Inactive "intel"
EndSection
Section "Device"

Driver "intel"

Tudo o que eu tentei mudar foi substituído na próxima inicialização ou login gráfico.
Eu adicionei nogpumanager às minhas opções de inicialização e recebi Configurações da Nvidia X Server para gerar essa configuração para mim:

De alguma forma, não foi sobrescrito na inicialização.
O que está causando as experiências não tão agradáveis que tenho e como resolvê-lo?
Drivers de gráficos, configurações de drivers e coisas que podem me impedir de inicializar-gui não são meus pontos strongs, então estou disposto apenas a tentar coisas que eu possa recuperar de se as coisas derem errado.
nogpumanager flag irá restaurar meu xorg.conf para os padrões. Eu tentei reproduzir o problema, mas algo mais aconteceu. Com um conjunto de programas abertos, o gui congelou no alt-tab e tornou-se preto. Todos os sons dos programas não pararam e consegui acessar os TTYs. Eu precisava reiniciar o lightdm para voltar ao gui.
