Told to KhronosGroup via Khronosdotorg repo’s github issue system that,
with akmod, GeForce GT710, on FC29, I have this issue.
I can reproduce it on my own code and I seen that
the first call to vkEnumeratePhysicalDevices fails
I have another machine where my code works,
but only the chip set Intel® HD Graphics 630
(Kaby Lake GT2) responds to this enumeration.
While a NVIDIA Corporation G86 GeForce 8400 GS is plugged in.
How to have it work?
