Map Viewer Window not showing anything

[ajsnyde]

Not sure what could be causing this, but the map viewer window is "blank" and shows a fixed image of what was behind it when it opened. The camera/video feed, however, functions normally. Running the basic tutorial after successfully building the docker. Host machine is Ubuntu 22.04 with xfce installed on top. https://user-images.githubusercontent.com/11302823/220725247-fdf29955-0595-46f3-8a39-a3d24d41aa92.mp4

• Is a nvidia GPU installed?
• Does glxgears work properly? (In host, In container)
• Does the same thing happen if you run docker with --cap-add IPC_OWNER?
• Does the same thing happen if you run docker with --ipc host?
• Does the same thing happen if you run docker with --privileged?
• Does the same thing happen if you run export LIBGL_ALWAYS_SOFTWARE=1 before running stella_vslam?

• Is a nvidia GPU installed?
  • yes, a 2080
• Does glxgears work properly?
  • yes, on the host machine it runs fine I added those arguments like so, without it fixing the issue: sudo docker run -it --rm --cap-add IPC_OWNER --ipc host --privileged -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix:ro stella_vslam-desktop

Finally, I ensured that export LIBGL_ALWAYS_SOFTWARE=1 was run before running the basic tutorial command: ./run_video_slam -v ./orb_vocab.fbow -m ./aist_living_lab_1/video.mp4 -c ../example/aist/equirectangular.yaml --frame-skip 3 --no-sleep --map-db-out map.msg, of course after downloading the vocab and materials listed in the tutorial.

As a workaround, I'm using the server/socket to run and display right now.

Do not use sudo to do docker run. See https://docs.docker.com/engine/install/linux-postinstall/

[ymd-stella]

yes, on the host machine it runs fine

What about when run inside a container?

• Is a nvidia GPU installed?
• host OS version
• container OS version
• Does glxgears work properly? (In host)
• Does glxgears work properly? (In container)
• Does the same thing happen if you run docker with --cap-add IPC_OWNER?
• Does the same thing happen if you run docker with --ipc host?
• Does the same thing happen if you run docker with --privileged?
• Does the same thing happen if you run export LIBGL_ALWAYS_SOFTWARE=1 before running stella_vslam?

It worked without GPU on Ubuntu 18.04. I think it will work on Ubuntu 20.04 or later, but it doesn't seem to work in some environments.

In my environment, I solved the problem by adding --privileged. documentation has been updated.
