Complete solution
Steel Browser docker compose fails on second run: Xvfb Fatal server error, Server is already active for display 10
Running Steel Browser's docker compose a second time kills the API with: (EE) Fatal server error: Server is already active for display 10 - If this server is no longer running, remove /tmp/.X10-lock and start again. Xvfb cant start because the previous run left a stale lock file in the container, and the entrypoint didnt clean it up. This isnt arm-specific, it happens on x86 too.
How to handle it
The Steel Browser entrypoint was fixed to remove stale X lock files on start (PR #56). Pull the latest image and rebuild with docker-compose up --force-recreate --build so the fixed entrypoint takes effect. As a one-off workaround on an already-running container, delete the stale lock: docker exec [api-container] rm -f /tmp/.X10-lock and restart. The maintainer acknowledged the fix on the issue and closed it.
