Linux Vulkan driver missing extensions

I'm came here to respond to this thread:


Extensions VK_KHR_surface and VK_KHR_win32_surface have disappeared


I noticed something similar in the Linux driver (16.15.2).  The ICD reports the instance extensions:


- VK_KHR_swapchain

- VK_KHR_xcb_surface


but not VK_KHR_surface.


Earlier versions of the LunarG loader would enumerate VK_KHR_surface anyway, and allow it to be used.  I bisected to this commit:


loader: ghlvl#79, Fix to not report unsupported WSI surface extension… · KhronosGroup/Vulkan-LoaderAndValidationLayers@c…


which was first released in 1.0.8.  After this change the loader will only enumerate VK_KHR_surface if the ICD enumerates it, causing the extension to be unusable.  Even the LunarG demos from the loader repo fail with:


"vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension."
