For a while vulkan-loader hasn't been working at all for me. Any application trying to use Vulkan just segfaults, and vulkaninfo errors out: ▶ vulkaninfo ========== VULKANINFO ========== Vulkan Instance Version: 1.1.106 /var/tmp/portage/dev-util/vulkan-tools-1.1.106-r1/work/Vulkan-Tools-2abb69904b9ad017d39d3da1e7fc3dec1a584cd8/vulkaninfo/vulkaninfo.c:5523: failed with VK_ERROR_INITIALIZATION_FAILED I've recently switched to the no-multilib profile, might that have something to do with it?
After more debugging this ended up being a simple permission problem. `RADV_DEBUG=all vkcube` showed me it couldn't open `/dev/dri/renderD128`. Trying it as root worked however. The solution was adding myself to the "video" group and relogging.
