Mostra que a placa NVIDIA foi detectada e nouveau está na lista negra. Mas também diz que o sistema não mudou. A saída de lspci -nn mostra que a placa ainda é um controlador 3D . Ambos nvidia-detect e nvidia-detector não detectam uma GPU NVIDIA.
O sistema está realmente usando o NVIDIA gpu?
Usando 14.10 de 64 bits no Asus X550LD (NVIDIA 820M).
Vá para o traço e clique em Configurações do servidor NVidia X, clique nos perfis PRIME e selecione NVIDIA (modo de desempenho).
Desligue e reinicie o seu sistema e verifique novamente as configurações do servidor NVIDIA x, você verá que o seu sistema está usando o seu NVIDIA Gpu.
