[Bug] Headless system crashes with SIGSEVG when starting app

[brandonscript]

Current Behavior

I'm not entirely sure what specifically is incorrect, or if anything, however I'm running a headless Ubuntu 22.04 box with docker, and though I connect to it with the Microsoft RDP client (since VNC no longer works on Ubuntu), I generally don't have a display connected.

When starting the app, I get an endless loop of errors:

[supervisor        ] service 'app' exited (got signal SIGSEGV).
[supervisor        ] waiting termination of logger thread of service 'app'...
[supervisor        ] logger thread of service 'app' successfully terminated.
[supervisor        ] restarting service 'app'.
[supervisor        ] starting service 'app'...
[supervisor        ] started service 'app'.
[supervisor        ] service 'app' exited (got signal SIGSEGV).
[supervisor        ] waiting termination of logger thread of service 'app'...
[supervisor        ] logger thread of service 'app' successfully terminated.
[supervisor        ] restarting service 'app'.
[supervisor        ] starting service 'app'...
[supervisor        ] started service 'app'.
# (etc.)

After some sleuthing:

1. Installing xhost and running xhost +: xhost: unable to open display ""
2. Running /startapp.sh: (fr.handbrake.ghb:20718): Gtk-WARNING **: 11:48:57.696: Failed to open display

I realized that there's no DISPLAY set, since there's no GUI session on the host. I tried adding DISPLAY=${DISPLAY} to my docker-compose file, and this got it a little further, but now xvnc is still failing to load:

Expected Behavior

There should be a way to configure the system to handle headless hosts (or perhaps I am doing something uniquely weird, and this is an RDP issue not a headless issue).

Steps To Reproduce

• Ubuntu 22.04 host
• Set up remote access in settings
• Connect with RDP client and/or ssh
• Install docker via linuxbrew (not Docker Desktop)
• Use the following docker compose:

name: docker-apps

services:
  handbrake:
    # image: jlesage/handbrake
    build: .
    container_name: handbrake
    runtime: nvidia
    restart: unless-stopped
    environment:
      - USER_ID=1000
      - GROUP_ID=1000
      - UMASK=002
      - LANG=en_US.UTF-8
      - KEEP_APP_RUNNING=1
      - DISPLAY=${DISPLAY}
      - DARK_MODE=1
      - TZ=America/Vancouver
      - CONTAINER_DEBUG=1
    ports:
      - "5810:5800"
      - "5918:5900"
    volumes:
      - /etc/docker/handbrake/config:/config
      - /etc/docker/handbrake/output:/output
      - /etc/docker/handbrake/storage:/storage
      - /etc/docker/handbrake/watch:/watch
    networks:
      bridge:
        driver: bridge

And based on this Dockerfile:

FROM jlesage/handbrake:latest AS handbrake
RUN apk add nvtop --repository=https://dl-cdn.alpinelinux.org/alpine/edge/testing
RUN apk add xhost

# Create /tmp/handbrake directory
RUN mkdir -p /tmp/handbrake && chmod 777 /tmp/handbrake && chown 1000:1000 /tmp/handbrake

Environment

• OS (local): macOS Sonoma 14.5 (23F79)
• OS (docker host): Ubuntu 22.04
• CPU (docker host): 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
• GPU (docker host): NVIDIA GeForce RTX 2060 / Driver Version: 545.23.08 / CUDA Version: 12.3
• Docker version: Docker version 26.1.3, build b72abbb

### Anything else?

_No response_

[brandonscript]

Exploring a little more with this, I've tried exec'ing into the container, and when I first ran DISPLAY=:0 HANDBRAKE_DEBUG=1 /startapp.sh, it failed with:

libEGL warning: MESA-LOADER: failed to open swrast: Error loading shared library /usr/lib/xorg/modules/dri/swrast_dri.so: No such file or directory (search paths /usr/lib/xorg/modules/dri, suffix _dri)

Digging around, it appears there's a missing driver, so adding this to a Dockerfile got me past that:

RUN apk add xhost xterm mesa-dri-gallium

Now when I run the startup script, it gets a little further, and actually writes out to the handbrake debug log:

Adding this to the Dockerfile fixes the XDG_RUNTIME_DIR error:

RUN mkdir -pv /xdgr && chmod 777 /xdgr && chown 1000:1000 /xdgr
ENV XDG_RUNTIME_DIR=/xdgr
ENV DISPLAY=:0.0

But then I get this in the hb debug log:

My leading theory is that this is related to the host running Wayland and the container attempting to exist in X11, and for some reason there isn't true isolation between the host and container. I'll continue to dig.

Could also be related to using the nvidia runtime in my docker-compose.yml.

[jlesage]

This container doesn't need anything from the host for display purpose. So you should definitely not set the DISPLAY environment variables, which might create problems since the container handles this variable itself.

The nvidia runtime might be the problem. Did you try without it ?

Do you see the same crash if you run docker run --rm jlesage/handbrake ?
