[BUG] GPU issues on Unraid

[BeattieBoy]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

GPUs cannot be enabled on Unraid. This was raised in a issue previously, but the thread seemed to be abandoned with no solution.

Expected Behavior

It should use the GPU...

Steps To Reproduce

Container boots but fails to get permission for the GPU and falls back to software rendering. The GPU(s) are detected (a 3080 on D128 and a Tesla P40 on D129), everything seems to go smoothly until

KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
[Wayland] GPU renderer failed to initialize (Failed to allocate GBM buffer); rendering in software (Pixman).

I have tried every combination of docker configs I can think of with no luck.

• Passing /dev/dri
• Defining DINODE and DRI_NODE
• modeset is configured in the bootloader and a cat /sys/module/nvidia_drm/parameters/modeset returns Y
• Adding NVIDIA_VISIBLE_DEVICES and NVIDIDA_DRIVER_CAPABILITIES (as many Unraid docker containers use)
• Running nvidia-modprobe --modeset after reboot and before launching the container

Environment

- OS: Unraid 7.1.4
- How docker service was installed: Compose
- Nvidia Driver: 580.82.09
- GPU: RTX 3080 (Tesla P40 installed but not trying to use that)

CPU architecture

x86-64

That is not how Nvidia works, given your compose start with the run command and work from there

https://docs.linuxserver.io/selkies/user-guide/gpu/#nvidia-proprietary-drivers

[BeattieBoy]

Pardon my confusion... This is a learning experience for me. But doesn't that just run a web-based Ubuntu image? Also based on the formatting of the instructions, I assumed that was for drivers between 595.80 and newer, which I do not have.

[thelamer]

You are running a 3080 on unraid the official runtime is on that version are you intentionally not upgrading ?

I don't care either way my main point was that compose example you have shown is not how the nvidia runtime works in compose, refer to the docs and start with minimal run commands run from the CLI on the server to see if you can get nvidia working on your host. I also have a 3000 series card and most of this stack is developed against that, but I do not run unraid so I could not tell you anything about how to configure that outside of the documentation and methodologies that have been contributed by unraid users with working setups.
