vkAcquireXlibDisplayEXT
To acquire permission to directly access a display in Vulkan from an X11 server, call:
VkResult vkAcquireXlibDisplayEXT(
VkPhysicalDevice physicalDevice,
Display* dpy,
VkDisplayKHR display);
physicalDeviceThe physical device the display is on.dpyA connection to the X11 server that currently ownsdisplay.displayThe display the caller wishes to control in Vulkan.
All permissions necessary to control the display are granted to the Vulkan
instance associated with physicalDevice until the display is released
or the X11 connection specified by dpy is terminated.
Permission to access the display may be temporarily revoked during periods
when the X11 server from which control was acquired itself loses access to
display.
During such periods, operations which require access to the display must
fail with an appropriate error code.
If the X11 server associated with dpy does not own display, or
if permission to access it has already been acquired by another entity, the
call must return the error code VK_ERROR_INITIALIZATION_FAILED.
One example of when an X11 server loses access to a display is when it loses ownership of its virtual terminal.
