Same bug here on two different laptop.
Fresh install Ubuntu 18.04.2
nvidia-driver-418
4.18.0-18-generic
First $vulkaninfo => OK
Switch on Intel with NVIDIA X Server settings
reboot
Switch to NVIDIA with NVIDIA X Server settings
reboot
$vulkaninfo => VK_ERROR_INITIALIZATION_FAILED
$sudo
In general nvidia-drm.modeset=1 is required to have Nvidia PRIME
enabled, which reduces (or even removes) tearing of moving images on
Optimus setups.
KMS - kernel mode settings, allows kernel to control video card and in Optimus
setups, among other features, this allows to synchronize graphics
I also had this same bug. Adding nvidia-drm.modeset workaround helped.

nvidia-drm.modeset=0 disables the vsync between the Intel and Nvidia

"I solved this just putting nvidia-drm.modeset=0 option into my grub
config."
I can confirm that this also solves the issue for me. Are there any
drawbacks to use this kernel parameter? I have tried googling around,
but I am still not sure what is actually does. And I am even more
curious how

yes, Gdm has issues with nvidia and KMS. Switching to Lightdm should
help.

So I think there is an issue regarding GDM and updated Nvidia
drivers...?
Well the issue with Nvidia settings is certainly releated to updated
Nvidia drivers

A temporary workaround is to switch gdm to another display manager

So, happens in Ubuntu 18.04 when you update the graphics drivers through PPA,
and ONLY when using GDM.
Happens in Ubuntu 18.10 without even upgrading graphics drivers. ALWAYS and
ONLY when GDM is used. Opengl works fine, vulkan doesn't.

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

Oh so it seems that Ubuntu 18.10 gdm and desktop defaults to Wayland,
that has probably something to do with GDM and the wayland session...
I defaulted GDM and Gnome to X...

I was wrong, you don't need to update.
Basically just works once when you first install on a fresh system the
nvidia proprietary drivers and reboot, in the first reboot it is already
using NVIDIA instead of Intel, and when this happens, all Vulkan
programs are running just fine. The problem comes
