Describe your issue:

Sleep behavior:  When AMDGPU-Pro driver is installed without VulkanSDK per instructions here: AMDGPU-PRO Driver for Linux Release Notes and here: How to Install LunarG Vulkan™ SDK for Ubuntu system will go into coma like sleep state where it is unable to wake.  Hard shutdown via power button and reboot is the only way to wake.  Behavior does not occur when only the AMDGPU-Pro driver is installed.
