Vulkan refuses to work :-( [solved]

Hello!
I am trying to play games based on the Vulkan API on my Arch machine, but Vulkan does not seem to work for me :-( I am running KDE plasma on a laptop with Intel UHD graphics 610. I have lib32-vulkan-icd-loader, lib32-vulkan-intel, vulkan-headers, vulkan-icd-loader, vulkan-intel, vulkan-tools, and vulkan-validation-layers installed. The output of vulkaninfo is as follows:
ERROR: [Loader Message] Code 0 : /usr/lib32/amdvlk32.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib32/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib32/amdvlk32.so: wrong ELF class: ELFCLASS32
ERROR at /build/vulkan-tools/src/Vulkan-Tools-1.2.162/vulkaninfo/vulkaninfo.h:668:vkCreateInstance failed with ERROR_OUT_OF_HOST_MEMORY

I can't seem to find anything helpful on the internet. I know that it is possible for vulkan to work, because it worked on the same hardware back when I still ran Ubuntu. Any help is appreciated :-)

Re: Vulkan refuses to work :-( [solved]

There seems to be some sort of AMD driver lurking somewhere on my system...
output of "expac -Qs '%n' vulkan-driver"
amdvlk
lib32-amdvlk
lib32-vulkan-intel
vulkan-info

Output of "ls /usr/share/vulkan/icd.d/"
amd_icd32.json amd_icd64.json intel_icd.i686.json intel_icd.x86_64.json

The two amd files above were also in a bolder, green font, while the Intel ones were not. Does that mean that I am using AMD Vulkan drivers, which are screwing up things?

Re: Vulkan refuses to work :-( [solved]

You need vulkan-intel (... the non-lib32 one is important for vulkaninfo) and none of the amd packages.

Cool! I deleted the amd files from /usr/share/vulkan/icd.d and now vulkaninfo works :-)
I am installing vkquake2 from the aur to test vulkan, and make sure everything works.

Re: Vulkan refuses to work :-( [solved]

They are package provided, there should be no reason for you to manually delete files provided by packages, just uninstall the amdvlk packages.

Please mark the topic as [SOLVED] by editing the title in your first post and adding that.

Cool. I uninstalled those, and it is even better now! :-)

Re: Vulkan refuses to work :-( [solved]

Fantastic. Thanks for this info. What I needed to do was `pacman -Rs amdvlk lib32-amdvlk`.
Then the two erroneous AMD json files in /usr/share/vulkan/icd.d/ were removed, and only the needed Intel ones remaining.

After that, vulkaninfo produces a large output, and no longer any error message.

Running Intel HD Graphics 620.
