Vulkan 不起作用

Question

我有一个 AMD FX CPU Nvidia GTX 650 ti 最新的 ubuntu 17.10 和 384.90 nvidia 驱动程序。

当我尝试在 Vulkan 下运行 Dawn of War III 时，我收到以下错误消息：

ubuntu 所需的 Vulkan 扩展 VK_KHR_surface 不可用

Vulkaninfo 输出：

如果您使用的是图形 PPA，请验证您是否强制使用了他们的软件包版本。17.10 升级后我遇到了类似的问题。运行 vulkaninfo 以验证您的加载程序是否“良好”。

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

你的 /usr/share/vulkan/icd.d/nvidia_icd.json 应该是这样的：

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

鉴于您的输出，您可能有一个看起来像这样的：

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