How to run demos using a remote display? #172
Description
I would like to be able to run the Space ROS Space Robots Demo Docker on a powerful headless server (hw2482) while displaying the Gazebo GUI on my local machine (delta).
Both hosts are running Ubuntu-desktop 24.04.1 LTS and can communicate via SSH.
Unfortunately I have been unable to accomplish my goal so far.
Here is what I tried:
-
On my local workstation (HW2228) I first log into the remote server using
ssh -Y hw2482 -
If I run some X client application on the server (for instance,
xlogoorxeyes), they are correctly displayed on my local machine:
-
However, when I execute the following instructions (from https://github.com/space-ros/docker/tree/main/space_robots#running-the-demos) to run the container on the remote server
# Logged in as gmacario@delta
ssh -Y hw2482
# Logged in as gmacario@hw2482
cd ~/github/space-ros/docker/space_robots
xhost +local:docker
./run.sh
# Inside container on hw2482
ros2 launch mars_rover mars_rover.launch.pyI get the X11 connection rejected because of wrong authentication. error as shown below:
gmacario@delta:~$ ssh -Y hw2482

The error makes me believe that the xhost +local:docker command was not sufficient.
Anybody has ever tried such use case?
