One of my machines has: % echo $DISPLAY :0
Digging deeper, I find in ~/.zprofile # MacPorts Installer addition on 2020-12-29_at_06:08:54: adding an appropriate DISPLAY variable for use with MacPorts. export DISPLAY=:0 # Finished adapting your DISPLAY environment variable for use with MacPorts. My other machine also has a ~/.zprofile, but it only sets the PATH. it does not set DISPLAY. I surmise that MacPorts stopped fiddling with DISPLAY sometime between late 2020 and late 2021. Maybe there should be some automatic check of DISPLAY in .zprofile, and a it could offer to clean it up if needed.
