I am trying to connect via ssh -X to a remote machine and from them run a docker with the graphical interface enabled.
I have found and tried to follow this tutorial: https://blog.yadutaf.fr/2017/09/10/running-a-graphical-app-in-a-docker-container-on-a-remote-server/
but I am getting the following error even with the final script
xterm: Xt error: Can't open display: :10
if I add a sudo chmod -R 777 display in the script I get this error instead:
X11 connection rejected because of wrong authentication. xterm: Xt error: Can't open display: :10
What I am missing? There is anything else I should configure either locally, on the remote machine or the container?
on local machine
