I am trying to run 'xhost +'  on CentOS 8 (such that I can grab a screen
but its not letting me.

On boot of X I run the "xhost +"
then later with SSH into hte box - I run
export DISPLAY=:0.0
gnome-screenshot -f jj.png
and I get the cannot open display message.

This works on the older CentOS 7.  What is the magic for C8?
