On Xorg, certain Vulkan processes attempt to start on the integrated GPU

[gammison]

Running arch on a Lenovo Y540 laptop. When using Xorg, the nvidia GPU properly runs the display manager and automatically runs all open gl applications. Certain vulkan programs though attempt to start and then black screen. One, the vkcube demo, stated it was attempting to run on integrated graphics. I had to use prime-run to force it back to the nvidia gpu at which point it ran fine. It's not clear at all to me how certain processes would attempt to start on the integrated graphics.

What's the output of glxinfo | grep "OpenGL vendor string"?

It doesn't output anything. I actually reinstalled vulkan tools and have not been able to reproduce the issue.
