How do I enable VK_KHR_xlib_surface?

Hi, I’ve successfully compiled RBDOOM-3-BFG on my Ubuntu 18.04 machine, and it does not run because " VK_KHR_xlib_surface extension is not enabled in the Vulkan instance". I can run all other Vulkan programs fine. Where can I enable/install this extension?

My guess is that you need to relog into X11 session instead of Wayland.

As @krOoze said, you need use X11 on Ubunty, also you can try to add Wayland support using

I’m using x11 (fluxbox as desktop), not wayland.

They seem to update daily. Vulkan support does not seem finalized. Try new version.

Check vulkaninfo if the extension is supported for you.

Otherwise you are probably best to ask at their repo. They would know best how to build and run their stuff.
