I have a docker container, and am wanting to use some GUI outside of the container. Problem is, when I try to open a GUI inside the container (for example firefox) it gives me the following Error (this message is from firefox):

Unable to init server: Could not connect: Connection refused
Error: cannot open display: :0

I tried to change the DISPLAY variable to MY_IP_ADDRESS:0, but that didn't really do anything. I also tried to disable access controll for xhost.

I normally start my container via docker-compose, but even when I just start it via the following command it gives me the same Error:

docker run -eDISPLAY=:0 -t -v /tmp/.X11-unix:/tmp/.X11-unix ubuntu:focal

I'm using Ubuntu 22.04 and all my packages are up to date.

Sorted by: Reset to default
