Estou tentando instalar o nvidia-driver para o Debian.
Li em todos os lugares que a solução correta é executar sudo apt install nvidia-driver e o driver deve se instalar sem problemas.
No entanto, este comando deixa-me com a saída

Eu tentei instalar as dependências ausentes (como sudo apt install nvidia-driver-libs ), mas isso só resulta em

Como eu instalo o nvidia-driver com o apt?
Você precisa ativar os repositórios não livres:
sudo sed -i.bak 's/stretch[^ ]* main$/& contrib non-free/g' /etc/apt/sources.list
Em seguida, execute apt update e tente sua instalação novamente. Você provavelmente também precisará instalar os cabeçalhos do kernel se ainda não tiver:
sudo apt install linux-headers-$(uname -r)
Como isso ainda não tem uma resposta aceita, vou em frente e corto o que funcionou para mim. Eu estava tendo um problema muito semelhante, com muitos dos mesmos pacotes reclamando, mas havia dois problemas adicionais de PreDepends que stretch-backports não estava resolvendo. Acontece que, além das instruções na página wiki postada por Stephen ( link ), eu precisava adicionar a contribuição de stretch . Ou seja, em /etc/apt/sources.list , eu mudei
deb http://ftp.us.debian.org/debian/ stretch main
para
deb http://ftp.us.debian.org/debian/ stretch main contrib
e executei apt update , após o qual consegui instalar nvidia-drivers sem problemas. Espero que ajude se você ainda tiver problemas.
