NVIDIA driver 440.44 / Vulkan vulkaninfo reports too many GPUs

Hi all -

I am using NVIDIA drivers 440.44 on Gentoo on a GE Force MX250. When I run vulkaninfo or any programs that enumerate the devices on my laptop, it always shows 2 with the exact same properties and UUID. Just trying to figure out why this may be. Could it be because I also have an integrated chip that I turn off? I just run straight through the discrete driver. I rarely, if ever have the igpu turned on.

Thanks for any tips.

I’ve seen a problem like this if nvidia-installer installs the Vulkan ICD file in /etc/vulkan/icd.d/nvidia_icd.json and a distribution’s driver package also puts one in /usr/share/vulkan/icd.d/. Do you have NVIDIA ICD files in both locations?

Yup- that was it. I disabled the one in /usr/share/vulkan/icd.d by renaming to nvidia_icd.json.disable and it reports only one. If I disable the one in /etc, well the info program crashes, which I thought was interesting, but obviously not a big deal. Thanks!
