Most examples fail on Ubuntu 16.04 Nvidia GTX680 Geforce 375.66 driver

After setting: #define ENABLE_VALIDATION true on all examples I get the error:

Could not create Vulkan instance : ERROR_LAYER_NOT_PRESENT

for the following examples:

• computenbody
• computerparticles
• computershader
• debugmarker
• deferred
• deferredmultisampling
• deferredshadows
• displacement
• distancefieldfonts
• dynamicuniformbuffer
• geometryshader
• instancing
• mesh
• multisampling
• multithreading: numThreads = 4
• raytracing
• scenerendering
• shadowmapping
• skeletalanimation
• specializationconstants
• sphericalenvmapping
• ssao
• terraintessellation
• tessellation
• texture
• texture3d
• texturearray
• texturemipmapgen
• texturesparseresidency
• vulkanscene

Are you sure that the validation layers are actually installed? Looking at your info.txt the only layers listed are those from steam, and not one single validation layer:

Layers: count = 2
=======
VK_LAYER_VALVE_steam_overlay_64 (Steam Overlay Layer) Vulkan version 1.0.3, layer version 1
    Layer Extensions    count = 0
    Devices     count = 1
        GPU id       : 0 (GTX 680)
        Layer-Device Extensions count = 0

VK_LAYER_VALVE_steam_overlay_32 (Steam Overlay Layer) Vulkan version 1.0.3, layer version 1
    Layer Extensions    count = 0
    Devices     count = 1
        GPU id       : 0 (GTX 680)
        Layer-Device Extensions count = 0

How do I install the Validation Layers?

[SaschaWillems]

Either build and install from source (https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers) or install a current version of the LunarG SDK for linux and follow the instructions at https://vulkan.lunarg.com/doc/view/latest/linux/getting_started.html.
