Problème driver et CUDA, nvidia gtx960M

Erhelito

Bonjour !
J'utilise comme carte graphique la Nvidia gtx960M, avec le dernier driver propriétaire (le 455).
Cependant, j'ai plusieurs problèmes :

- le logiciel des paramètres de la carte (celui installé automatiquement lors de l'activation du driver) est très incomplet, je peux juste choisir si je veux utiliser la carte Nvidia, ou le processeur comme carte graphique.

- lorsque je fais la commande

nvidia-smi

j'ai cette erreur :

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

- depuis peu, je me suis mis à blender, j'ai voulu activer le rendu GPU. Pour cela, il faut que la carte graphique soit compatible CUDA (après vérification, ma carte est compatible). Blender me dit que je n'ai pas de carte graphique compatible CUDA (je crois qu'il faut un logiciel supplémentaire, mais je ne suis pas sûr. Je vais déjà essayer de faire fonctionner ce driver correctement...)

J'ai déjà fait plusieurs recherches, essayé plusieurs méthodes, mais rien ne marche...

Merci de vos réponses !

Bonjour,

Montre, en te servant du Retour utilisable de commande :

lspci -vnn | grep -A12 '\''[030[02]\]' | grep -Ei "vga|3d|display|kernel"

ubuntu-drivers devices

uname -a

et :

dpkg -l | grep nvidia

dpkg -l | grep -v ^ii

Erhelito

J'ai ceci :

Il est écrit que je dois redémarrer.
Et ensuite ?

xubu1957

Tu auras un système plus propre.

Je n'ai pas l'habitude du nvidia-settings, voir le § 4.1.

Il faudrait les conseils des connaisseurs.

Erhelito

OK !
J'ai essayé de réinstaller le paquet Nvidia settings, mais il n'y a aucun changement...

xubu1957

Je n'avais pas vu cette Doc [doc]cuda[/doc], je ne saurais pas t'aider.

Erhelito

Sur les ordinateurs portables la technologie optimus est souvent utilisée, si vous installez cuda avec les options par défaut vous risquez de vous retrouver avec un écran noir au démarrage ( l'installation standard désactive la carte intégrée qui est utilisée pour "afficher" l'écran ).

J'ai pas trop confiance...
Je pense que je vais me faire un dual boot windows pour utiliser les logiciels de 3D proprement, avec les bons drivers et cuda...

xubu1957

Tu as aussi [doc]nvidia_optimus[/doc]

Erhelito

J'avais déjà vu cela, mais mon pc portable reste sur mon bureau, et est relié au secteur, donc le pb de l'économie d'énergie ne se pose pas, j'ai activé la Nvidia comme carte graphique par défaut.
J'ai cependant une question qui me vient : Comment pourrais-je voir l'activité de ma carte graphique ? Sur le system monitor, je ne vois que l'utilisation des coeurs de mon processeur, de la ram et d'internet.

Merci !
Je vais tester ça plus tard (je suis en télétravail, si je fais une couille et que je dois la réparer...)
