Multiple Display Errors when launching the TDW docker image in a remote server

[YanjunChen329]

Hi,

I am trying to use the TDW docker image in a remote Ubuntu server. Due to the display limitation of my remote server, I have to launch a specialized docker container in my server and run an X server there so that I could connect the display to my local desktop through VNC. This workflow works fine for other applications so I was thinking about launching the TDW docker image from my container.

My docker container for display has Ubuntu version 18.04.3. When initializing it, I passed options

-v /var/run/docker.sock:/var/run/docker.sock
-v /usr/bin/docker:/bin/docker

into the RUN command.

However, when I build the TDW docker image, the building hangs in the last step: RUN ./TDW/TDW.x86_64.

I suspected that maybe ./TDW/TDW.x86_64 is an application with GUI, so I skipped the last step and launch the TDW image within my container. This is the command I use:

sudo docker run -it \
    --rm \
    --gpus all \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e DISPLAY=$DISPLAY \
    --network host \
    tdw:v1.6.0

However, when I run ./TDW/TDW.x86_64, the prompt still hangs there with no response, neither could I see anything from my display. I tried to run xclock but it says Error: Can't open display: :0. I tried to do some troubleshooting and found that my X11 socket file /tmp/.X11-unix/X0 is successfully passed into the TDW container, but it is identified as a directory instead of a socket.

In the TDW container

In my display container

I am a newbie in this and I couldn't figure out what happened.

After I failed to launch the TDW container with the Docker within Docker approach, I tried to install an X server and VNC display directly in the TDW container. I successfully see the display on my local desktop. Running xclock in the TDW container also pops up a window in the display. However, when I tried to run ./TDW/TDW.x86_64, the following error shows up:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  150 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  87
  Current serial number in output stream:  88

It seems to be an OpenGL problem and I have no idea how to solve it. Any feedback or suggestion on this is much appreciated! Thank you for the time!

Hi - have you tried using xpra to view a remote render? Here is a link to our documentation on this approach:

@YanjunChen329 What is the output of nvidia-smi? Your drivers might be out of date.

Hi,

Thank you for the prompt replies! I tried to follow the instructions in the link that @jemsMIT provided. However, I still encountered the same "Can't open display: 80" error. Here is the details of my steps:

First, I can't run step 2: DISPLAY=:80 vlgrun -d :0 ./tdw.x86_64 because my host container does not have ./TDW.x86_64. I assumed that this is the command I should run when I am in the TDW container. Thus, I followed the shell script tdw/Docker/start_container_xpra.sh for server-side code. Here are the commands I run:

DISPLAY=:0
xhost +local:root
xpra start :80
DISPLAY=:80
xhost +local:root

sudo docker run -it \
  --rm \
  --gpus all \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -e DISPLAY=$DISPLAY \
  --network host \
  vglrun -d :0 \
  tdw:v1.6.0 \
  ./TDW/TDW.x86_64

However, for the last command docker complains that no image vglrun can be found. I think this is a small typo in the shell script so I run the following command instead:

sudo docker run -it \
  --rm \
  --gpus all \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -e DISPLAY=$DISPLAY \
  --network host \
  tdw:v1.6.0 \
  vglrun -d :0 ./TDW/TDW.x86_64

After it started running, I went to my Mac and tried the command xpra attach --ssh=ssh ssh/<my_server_hostname>/80. However, the following error shows up:

Warning: vendor 'Intel Inc.' is greylisted,

I also tried to connect to my xpra server through web browsers following a tutorial online. I managed to see the Xpra favicon but immediately after, an error message popped up saying: ERROR CODE: GPU_DEAD_ON_ARRIVAL

---

The thing that baffles me the most is that I received the OpenGL error after I installed X-server and VNC on the TDW docker image. Is there any dependency that I may be lacking or is there any other approach that I could try? Thank you again for your help!

@alters-mit My remote server has driver version 430.5. Here is the output from running nvidia-smi:

@YanjunChen329 I found numerous problems with TDW's Docker container, which I fixed. Try upgrading: pip3 install tdw -U and see our Docker documentation

Please let me know if that helps solve your problem.
