Issue on running the demo #96

Closed pyrotank41 closed 11 months ago

pyrotank41 commented 1 year ago

I am following the tutorial for Visual SLAM with Isaac Sim here. Upon running the following line:

source /workspaces/isaac_ros-dev/install/setup.bash && \
>   rviz2 -d src/isaac_ros_visual_slam/isaac_ros_visual_slam/rviz/default.cfg.rviz

i am getting the following error:

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted (core dumped)

The remote platform where the docker is running: Ubuntu 22.04 Development computer (where I am working): Macbook pro m2 pro

XQuartz is running and forwarding the GUIs from the remote machine.

Any suggestions on how i can fix the problem?

This sounds like an issue relating to display forwarding, and not something specific to Isaac ROS. This thread suggests that you might need to install some additional dependencies inside the container to allow for display forwarding.

You might also consider using Foxglove to visualize the data directly from a browser window on your Macbook Pro. I've also found that using a "headless" HDMI dummy plug installed on the remote computer can be helpful in solving weird display forwarding quirks.
