Launcher: cannot connect to X server

[atk5025]

I'm not sure there's something for this repo to fix or perhaps just update the documentation. I ran into an error trying to run the image per the commands in the readme file

Running Ubuntu 18.04.4 LTS

Command Input
docker run --net=host --rm -e DISPLAY -e QT_X11_NO_MITSHM=1 ballaerospace/cosmos

Command Result
No protocol specified
Launcher: cannot connect to X server :0

Fix
Fixed by entering this command on the command line and attempting again
xhost local:root

I see the same issue after a reboot. I can fix it with a similar command to above or using startx then exiting.

xhost local:$(whoami) will also correct this issue.

The xhost fix doesn't seem to do anything on RHEL 8. Same error:
