​​​​​​​Hi @alaurenzi ,

I've a problem with the docker when I launch gazebo for this reason:

Hi @DavideAntonucci, can you list the exact steps leading to the error?

DavideAntonucci commented

Hi @alaurenzi ,

  1. I've installed the docker and followed the Post-installation steps for Linux, ONLY this one: Manage Docker as a non-root user.
  2. ./docker/run.sh runs the container.
  3. I tried to launch gazebo as you can see in the first comment. I did this because, ./start.sh (starts roscore and but NOT gazebo).

Unfortunately it looks like an incompatibilty issue with your video drivers.. I cannot reproduce the issue on either of my machines. Did you try

  • to mount your nvidia drivers onto the guest machine as described here (requires editing run.sh and exporting some env variables)
  • to install the nvidia drivers directly on the guest machine as reported here?

Alternatively, you should be able to run just the gazebo backend (replace gazebo with gzserver in the start.sh script). A web frontend server is run by the start.sh script, and should be accessible at localhost:8080 on the host machine.

Unfortunately, for this point:

I cannot run gzserver for this reason:
libGL error: failed to load driver: swrast.

Moreover, I cannot reach the localhost:8080, it seems that the docker doesn't have internet connection, How I can resolve it?

alaurenzi commented

Without gzserver, the gzweb probably won't open the connection, probably that's why you can't see anything in the browser.

Same identical problem here, with same steps followed.

  • to mount your nvidia drivers onto the guest machine as described here (requires editing run.sh and exporting some env variables)

With this, nothing change for me

I tried to enter docker as root (adding --user root \ in the run.sh) and installing drivers as described above (apt update && apt install -y nvidia-340 mesa-utils && glxgears).
The problem is not present anymore, but I have this one:

Maybe related: jessfraz/dockerfiles#6

I tried xhost local:docker and its variants, before running the docker image and after, nothing.

I am almost sure that I does not have change anything, but this error does not happen anymore.
Instead, a new one is there:
