vulkan-nouveau causing vulkaninfo OOM but nothing else(?)

DarthOrdo · Yesterday 12:24:07

I've recently installed the NVK Vulkan driver because my OBS wasn't working with the NVIDIA drivers (didn't create a window and wouldn't exit by any means). This seems to have worked, I've got applications like Godot using my NVIDIA card with Vulkan and 'NVK GB207' showing up in brackets. When I run 'vulkaninfo' however, I get the following error:

ERROR at /usr/src/debug/vulkan-tools/Vulkan-Tools/vulkaninfo/./vulkaninfo.h:249:vkGetPhysicalDeviceDisplayPlanePropertiesKHR failed with ERROR_OUT_OF_HOST_MEMORY

Looking at other similar errors they seem to be from either conflicting drivers or drivers not loading(?). I only have 'vulkan-intel' and 'vulkan-nouveau' installed so I don't really see where the problem would be.

For some reason, after a while (or doing something I don't understand) 'vulkaninfo' doesn't OOM anymore, showing both GPUs correctly (with NVK on the NVIDIA card).

Any idea what the issue could be? I'm worried that even if everything else seems to work, I might have something installed wrong.

https://archlinux.org/packages/extra/x86_64/nvtop/
https://archlinux.org/packages/extra/x8 … gpu-tools/ (intel-gpu-top)

vulkaninfo --summary

and you can control which vulkan implementation to use,

ls /usr/share/vulkan/icd.d/
export VK_DRIVER_FILES=/usr/share/vulkan/icd.d/<driver_here>_icd.json

Installing and running 'nvtop' and 'intel_gpu_top' displays my integrated Intel GPU but not the NVIDIA card. Running a program using the NVIDIA card (via DRI_PRIME or just Godot using it by default) displays it as using 0% GPU but does seem to be using the it (Godot and glxinfo report NVK), it's just not being detected.

vulkaninfo --summary

doesn't do anything different to the raw command, throws the same ERROR_OUT_OF_HOST_MEMORY error and exits, nothing else happens.

Running 'vulkaninfo' with VK_DRIVER_FILES exported as 'intel_icd.json' works when 'vulkaninfo' would otherwise be OOM-ing but only shows the Intel card. 'nouveau_icd.json' OOMs so the issue is specifically with NVK (I assume specifying the driver files limits 'vulkaninfo' to detecting only one driver?).

Hold on, you're using nvidia? Remove vulkan-nouveau.
Also post the output of

qdbus6 org.kde.KWin /KWin supportInformation

and your complete system journal for the boot:

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

Nvidia shows usage in "nvidia-smi"

To clarify, I would like to be able to use my discrete NVIDIA GPU for Vulkan using NVK (vulkan-nouveau). I have uninstalled nvidia-open and nvidia-utils because they weren't working and vulkan-nouveau was. Thinking about this a bit more I assume vulkaninfo is just more pedantic than most applications and that the bug I'm experiencing is some combination of NVK being unstable and my GPU being from 2025.

For clarity : what is the output of

$ MESA_VK_DEVICE_SELECT=list vulkaninfo
