MissingExtension VK_KHR_xlib_surface

[JustMaximumPower]

When I try to run the examples on Ubuntu 16.04 I get the following error:

thread '

' panicked at 'called Result::unwrap() on an Err value: SurfaceCreationError(MissingExtension { name: "VK_KHR_xlib_surface" })', ../src/libcore/result.rs:746

The vulkan samples from SaschaWillems all run fine, so I think its not a problem of the vulkan install.

I’m running vulkano on Ubuntu 16.04 x64 with an AMD R9 380X with AMDGPU-Pro 16.30.3.

The vulkan examples of SaschaWillems use xcb, not xlib.

Sadly, xlib support is not yet implemented in the intel linux driver. You can double check this with vulkaninfo | grep xlib.

You can however run vulkano in a wayland context (like weston) and the examples should run fine. (I get a segfault in libwayland_client at some point, but that I think is a bug in the intel driver.)

I'm going to close this, as the relevant issue is rust-windowing/winit#5

Unfortunately this is a problem with the windowing library used by the examples that only supports Xlib (and Wayland) and not XCB. Right now vulkano-win checks for wayland, and if it doesn't work assumes that xlib will work. Hence the problem.
