Description
This is extension, along with related platform extensions, allows applications to take exclusive control of displays associated with a native windowing system. This is especially useful for virtual reality applications that wish to hide HMDs (head mounted displays) from the native platform’s display management system, desktop, and/or other applications.
New Enum Constants

VK_EXT_DIRECT_MODE_DISPLAY_EXTENSION_NAME -
VK_EXT_DIRECT_MODE_DISPLAY_SPEC_VERSION
Issues
1) Should this extension and its related platform-specific extensions
leverage VK_KHR_display, or provide separate equivalent interfaces.
RESOLVED: Use VK_KHR_display concepts and objects.
VK_KHR_display can be used to enumerate all displays on the system,
including those attached to/in use by a window system or native platform,
but VK_KHR_display_swapchain will fail to create a swapchain on
in-use displays.
This extension and its platform-specific children will allow applications to
grab in-use displays away from window systems and/or native platforms,
allowing them to be used with VK_KHR_display_swapchain.
2) Are separate calls needed to acquire displays and enable direct mode?
RESOLVED: No, these operations happen in one combined command. Acquiring a display puts it into direct mode.
