Running carla without display

[tanglrHello]

I've found several ways to start carla server without display:
(1) https://carla.readthedocs.io/en/latest/carla_headless/
In this documentation, several tools are required to be installed
(2)https://carla.readthedocs.io/en/latest/configuring_the_simulation/#running-off-screen
But in this documentation, only assign an empty value to DISPLAY will do
(3)#225
No display and select gpu.

In my local desktop ubuntu system, the second method seems to work well. But I always get a core dump then I start carla on remote servers as described in #1101.
My situation is: I have several remote headless server machine with nvidia driver installed (but I'm not sure if they're installed with opengl). And I want to start carla on those remote machines. I think I'd better use docker to avoid some common deployment in multiple machines. And if I pull the docker carlasim/carla:0.9.1 from with the instruction in this documentationhttps://carla.readthedocs.io/en/latest/carla_docker/#getting-it-running, I can run it successfully on my local desktop system, but have signal 11 caught when running on those remote servers. Even the server has a newer nvidia driver than that on my local system.

And to sum up my question:

1. What's the difference behind those ways for starting carla without display?
2. With nvidia driver properly installed on remote server, can I directly use the docker image named carlasim/carla to start a carla server? Or I should follow the instruction in https://carla.readthedocs.io/en/latest/carla_headless/ and install those tools into the docker image? Or something else? But nvidia-xconfig seems not to be supported
3. In what circumstances should I install OpenGL, VirtualGL(VGL), TurboVNC 2.11 mamually? Maybe quite the same as the first one.

hi buddy, have you solved this issue? i occurred the same problems, i also have a remote server equipped with a GPU, but i always got signal 11 or 6 error when i launch the CarlaUE4.sh (version==0.8.2). In addition, my remote server had install the OpenGL 3.0, but it seemed the UE4.18 needs OpenGL4.3 at least.

Hello all, any update on this problem? I am also confused with the same problems proposed by tanglrHello.

Same here, @Derekabc , the documentation could use some updates/clarification. I'm using approach 2 with CARLA 0.9.5's Docker container. I'm not trying to x-forward the server's display, instead I'm relying on data being dumped to the filesystem via the PythonAPI client. Seems to work, but some of the messages I'm seeing in the logs make me uneasy (will likely create a separate ticket).

I have same problem, do you use xorg to start DISPLAY in docker?
