I'm running it on windows10 and see a black screen too.
I've got these two validation errors:

validation layer: Validation Error: [ UNASSIGNED-CoreValidation-Shader-InputNotProduced ] Object 0: handle = 0x83d4ee000000000b, type = VK_OBJECT_TYPE_SHADER_MODULE; | MessageID = 0x23e43bb7 | Vertex shader consumes input at location 0 but not provided
validation layer: Validation Error: [ UNASSIGNED-CoreValidation-Shader-InputNotProduced ] Object 0: handle = 0x83d4ee000000000b, type = VK_OBJECT_TYPE_SHADER_MODULE; | MessageID = 0x23e43bb7 | Vertex shader consumes input at location 1 but not provided

I cannot reproduce this problem on either Arch Linux or Windows 10 (NVIDIA GTX 1070 with latest drivers) and it seems like a strange error given that the shader doesn't have any inputs. Make sure that you've really compiled the right source file to the right output files.
