With the code as of today, If I don't symlink /usr/lib/x86_64/libdl.so.2 the NeoDemo application runs, but Vulkan is grayed out (only OpenGL is available). Symlinking libdl.so.2 to libdl.so, which seems to be needed to have Vulkan detected, the demo tool crashes at start-up due to failing this check

            if (!GetPresentQueueIndex(out _presentQueueIndex))
            {
                throw new VeldridException($"The system does not support presenting the given Vulkan surface.");
            }

in public VkSwapchain(VkGraphicsDevice gd, ref SwapchainDescription description, VkSurfaceKHR existingSurface)
at veldrid/src/Veldrid/Vk/VkSwapchain.cs:line 71

Output of vulkaninfo is attached,

I don't really understand the cause of the failure; is there a way to fix this?
