dpkg --get-selections | grep nvidia retorna

nvidia-smi,noentanto,retorna

NVIDIA-SMIhasfailedbecauseitcouldn'tcommunicatewiththeNVIDIAdriver.MakesurethatthelatestNVIDIAdriverisinstalledandrunning.

e

lspci-v|grep"controlador VGA" retorna

00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06) (prog-if 00 [VGA controller])

que parece indicar que a nvidia não está sendo usada?

Alguém poderia me indicar a direção certa para resolver isso?

Muito obrigado

EDIT: IMPORTANTE

nvidia-settings informou que o driver NVIDIA não está carregado e que não encontrou o arquivo de chave do Registro

    

Answer 1

A nvidia é conhecida por ter problemas com o linix. você precisa dos drivers proprietários. os drivers nvidia mais comuns estão disponíveis no repositório restrito / não-livre. istalling os drivers devem corrigir todos os problemas nvidia.
