I have no idea if this is the current case, but some drivers have multiple names, like so:
Code:
# ls -l /usr/lib64/dri/ | grep 688
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 i830_dri.so
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 i915_dri.so
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 i965_dri.so
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 nouveau_vieux_dri.so
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 r200_dri.so
-rwxr-xr-x 6 root root 16335688 Jan 28 15:23 radeon_dri.so
This dri file, obviously applicable to AMD and Intel and NVidia GPUs, has a total of 6 hard links - 6 names for one file. If this is the case with vulkan, vulkan info simply may not be programmed to ignore the inapplicable name in its report. Or, it could be reporting on account of the "disabled" iGPU.
