Oh actually no I don't know...It's really strange and frustrating when this happens, because I was able to reproduce the problem on an Ubuntu 18.04 based distro using GDM as display manager... A way to make it working is to run "vulkaninfo" as sudo once, it works, then also without sudo is back to work again once you reboot...
