Vulkan ne fonctionne pas

J'ai un processeur AMD FX Nvidia GTX 650 ti à jour ubuntu 17.10 avec 384.90 pilotes nvidia.

Lorsque j'essaie de lancer Dawn of War III sous Vulkan, le message d'erreur suivant s'affiche:

ubuntu requis L'extension Vulkan VK_KHR_surface n'est pas disponible

Vulkaninfo renvoie:

Si vous utilisez les graphiques PPA, vérifiez que vous avez forcé leur version des packages. J'ai eu un problème similaire après la mise à niveau de 17.10. Exécutez vulkaninfo pour vérifier que votre chargeur est "bon".

PPA: https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa

Votre /usr/share/vulkan/icd.d/nvidia_icd.json devrait ressembler à ceci:

{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "libGLX_nvidia.so.0",
        "api_version" : "1.0.49"
    }
}

Vous en avez probablement un qui ressemble à ceci en fonction de votre sortie:

{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "libGL.so.1",
        "api_version" : "1.0.49"
    }
}
