Yes, I know that. As I said, it was set correctly. It's not set that
way anymore because I went back to the standard X11.app for now.

Ok, glad to hear it.

I have RTFM many, many times, and that is a complete surprise to me.
Sorry, that's definitely not in the man page:
list [-x] [label]
With no arguments, list all of the jobs loaded into launchd in
three columns. ...
In fact, the entire man page makes no mention of *any* difference
between running as root and as a user, except obliquely as a mention
that LaunchAgent config files must be owned by the user loading them.
This behavior is very strange, very unexpected. Looking back, it
probably explains why nearly every interaction I've had with launchctl
has ended in failure and frustration. I'm sure I was using sudo, or
not using it, at the wrong moment. Sorry, I know this is off topic
but I can't tell you how many times launchctl has spoiled my
So you can't even get a list of the running LaunchDaemons without
superuser access? Is there some security reason for that?
