Vulkan does not work on new Installation

My Problem is the following:

On a new Installation (Switching from Manjaro) Vulkan does not work (i.e. most Steam Games won’t start.

I installed vulkan-radeon and lib32-vulkan-radeon and vulkaninfo prints this

WARNING: [../mesa-24.3.2/src/amd/vulkan/radv_physical_device.c:2037] Code 0 : Device '/dev/dri/renderD128' is not using the AMDGPU kernel driver: Invalid argument (VK_ERROR_INCOMPATIBLE_DRIVER)
ERROR: [Loader Message] Code 0 : setup_loader_term_phys_devs:  Failed to detect any valid GPUs in the current config
ERROR at /usr/src/debug/vulkan-tools/Vulkan-Tools-1.4.303/vulkaninfo/./vulkaninfo.h:247:vkEnumeratePhysicalDevices failed with ERROR_INITIALIZATION_FAILED

Vulkan worked using Manjaro so my device is compatible

I am clueless. Could someone help me please?
Thanks in advance

Found some reports of adding following kernel parameters outlined on wiki solving this problem: https://wiki.archlinux.org/title/AMDGPU#R9_390_series_poor_performance_and/or_instability

DRM_AMDGPU_CIK kernel parameter is also noted on Gentoo wiki under Feature support

The kernel parameters did the trick.
Thank you so much. :slight_smile:
