Vulkan不起作用
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必需Vulkan扩展VK_KHR_surface不可用
Vulkaninfo输出：

而hwinfo --gfxcard输出是：

如果您正在使用图形PPA，请确认您强制使用其版本的软件包。 17.10升级后我遇到了类似的问题。 运行vulkaninfo以validation您的加载程序是否“正常”。

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" } }
根据您的输出，您可能会看到这样的：
{ "file_format_version" : "1.0.0", "ICD": { "library_path": "libGL.so.1", "api_version" : "1.0.49" } }
