Hello everyone, I have an issue with my vulkan install. Here is my general problem : I use my linux computer to play video games and I encounter instabilities with Blizzard’s Battle net. It seems to me that a good idea would be to identify the versions of the working installation (Proton, DXVK, Vulkan) and save them for backup or to prevent upgrades that could break it.
Concerning vulkan, my problem states as follow : I don’t know which is my current used implementation nor to which package and dynamic library it corresponds. It seems that there is 3 different implementations on my system : the default, one of AMDVLK and RADV. To make it clear, here are the commands used to switch between them :
- doing nothing results in the default one
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/amd_icd64.jsonresults in the AMDVLK oneexport VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.jsonresults in the RADV one
If it can help, I uploaded the corresponding vulkaninfo --show-all outputs here (txt and html formats).
Of course, Battle net works only with the unidentified one. I would like to obtain the following informations about it : type (amdvlk or radv), version(s), associated dynamic libraries paths, package name in my package manager. Can somebody help me to gather (even a part of) these infos ?
As a related question : since the default implementation is not associated to the previous mentioned icd files, can I generate one in order to make the install cleaner ?
Here is my neofetch output :

Thank you very much for your attention and help !


Disclaimer, without doing a bunch of digging, my advice will be limited.
Some questions, are you using X11 or wayland?
Are you launching battle.net through a different method than the games that do work, i.e. are all your steam games running fine but you launch battle.net through lutris or bottles or something?
How long has your install been up and running?
It looks like the vulkan that works is a slightly higher version than the amd and rad ones (the first lines from the files you posted). Vulkan should be getting pulled in by Mesa, i would check to see if you have multiple versions of Mesa installed as well.
Depending on the cutoff year (when amdgpu as a default driver got replaced with RADV) , whether your cpu has a igpu (again, didn’t look up what gen those where), you could have 2 separate AMD drivers being installed, one for your igpu, and one for your dgpu.
Also the ones that are labeled (that don’t work but do output when you run those commands) could be used and pulled in because of X11, where the “unidentifed” is being used by wayland) i could be misreading, but i belive that command around pathing is more for X11 than wayland.
TLDR: the versions should be the first line in the texts you shared. Id figure out what is pulling and installing all 3 of those as deps for you to end up with them on your machine (unlabeled probably mesa, amd and rad probably drivers), and to research id look for some tools to debug and log what happens when you run a program so you can see the paths and LIBS hit.
Looks like you probably already hit this link: https://wiki.archlinux.org/title/Vulkan
