It prints this before segfaulting:

Xlib:  extension "NV-GLX" missing on display ":0".
Segmentation fault (core dumped)

However, the triangle, and teapot both print the same (but do not segfault), as well as: Using device: Intel(R) HD Graphics 620 (Kaby Lake GT2) (type: IntegratedGpu)

I'm on latest master:

commit 23709fb0117b569a8c7e35b36b929938361f1dba (HEAD -> master, origin/master, origin/HEAD)

    Remove vulkano-shader-derive (#1085)

I can confirm that I have the same issue. I have the exact same integrated device "Intel(R) HD Graphics 620 (Kaby Lake GT2)" However I have an amd discrete card so I dont get the message NV-GLX.

Ran with the validation layers enabled and get:

Same errors as mentioned here https://github.com/vulkano-rs/vulkano/issues/1063

Just confirming that I also run into this with the exact same integrated device.

GPU id       : 0 (Intel(R) HD Graphics 620 (Kaby Lake GT2))        

Had the same problem, but now woks fine.

5.0.5-arch1-1-ARCH
vulkan-intel 19.0.1-2
Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2)

Yes I can confirm this is fixed for me too, also on Arch with vulkano-intel drivers and a Intel HD 320.
