[BUG] DBus hostname1 permission error

[neo2l33t]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The Selkies web UI loads successfully and the remote desktop stream starts, but Bambu Studio itself does not remain open. On container start, the Bambu Studio window appears briefly, then disappears/exits.

The logs show the container launching Bambu Studio as:

/opt/bambustudio/bin/bambu-studio

but DBus reports:

dbus-daemon[432]: [system] Activating service name='org.freedesktop.hostname1' requested by ':1.12' (uid=99 pid=562 comm="/opt/bambustudio/bin/bambu-studio") (using servicehelper)
dbus-daemon[432]: [system] Activated service 'org.freedesktop.hostname1' failed: Failed to execute program org.freedesktop.hostname1: Permission denied

The container also logs:

No desktop processes found to terminate.

Selkies continues running, but Bambu Studio is not usable in the browser.

Expected Behavior

No response

Steps To Reproduce

Deploy lscr.io/linuxserver/bambustudio on Unraid.
Use PUID=99, PGID=100, PIXELFLUX_WAYLAND=true, AUTO_GPU=true, DRI_NODE=/dev/dri/renderD128, DRINODE=/dev/dri/renderD128.
Start the container.
Open the WebUI on HTTPS port 3001.
Observe Selkies loads, but Bambu Studio flashes briefly and exits.

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

[j0nnymoe]

What CPU have you got? Have you tried without passing through your nvidia card?

[neo2l33t]

It does work on the CPU, but it doesn't use the GPU for anything. CPU is a AMD Ryzen 7 5800X

[j0nnymoe]

Did you follow the steps here around nvidia? https://github.com/linuxserver/docker-bambustudio#nvidia-proprietary-drivers

[j0nnymoe]

Also worth noting that you might have issues with a 1080 considering it's 10 years old.

[neo2l33t]

Yup, I added those parts to the unraid syslinux cfg, the --gpus all....

[j0nnymoe]

Ok, but going off the information you've provided, the docker run you've provided doesn't show the --gpus all --runtime nvidia.

[neo2l33t]

The GPU is old but works fine for everything else thrown at it (from ollama to SD to emby and others) and this wasn't an issue until a month or 2 ago. Something changed in the meantime and it just doesn't play nice.

[thelamer]

Nvidia has become a moving target. I run head drivers to identify different issues that arise what I need to do now to get nvidia 595.80 to work is:

1. Dummy plugs and kernel params are not needed anymore.
2. Once per boot I need to run nvidia-modprobe --modeset this creates the /dev/nvidia-modeset device file
3. I need to manually mount this into the container with --device /dev/nvidia-modeset

Full bare minimum run command for me:

docker run --rm -it \
  --shm-size=1gb \
  --device /dev/nvidia-modeset \
  --runtime nvidia \
  --gpus all \
  -e AUTO_GPU=true \
  -p 3001:3001 \
  linuxserver/bambustudio bash

Just as a side note with 580, I needed a dummy plug and the kernel params as laid out in the readme.

[neo2l33t]

Sadly, still doesn't work for me. I'm using --shm-size=1gb --gpus all --runtime nvidia --device /dev/nvidia-modeset and also auto_gpu=true dri_node=/dev/dri/renderD128 DRINODE=/dev/dri/renderD128 PIXELFLUX_WAYLAND=true

it loads as 1MB into the GPU but that's it.

But when I PIXELFLUX_WAYLAND=false and remove dri_node=/dev/dri/renderD128 DRINODE=/dev/dri/renderD128 it does load into the GPU and then it crashes when I try to open anything.

[thelamer]

This might just be upstream, you could try much older versions of bambustudio by changing the version in the docker file and building it or downloading the app image decompressing it and testing different versions in session bambulab/BambuStudio#10668

[neo2l33t]

Thanks. I'll give that a try. I think I'll have to roll back or just accept the CPU rendering/loading
