Why does /usr/bin/{users,w,who} not output me when logged into xfce4

Within the past few months, I am invisible from /usr/bin/users it seems (running it gives a null). Is this true for others? I am running lxdm+xfce4 and logging locally.

EDIT: Neither /usr/bin/w nor /usr/bin/who nor /usr/bin/users finds me

Even running them as root gives no output that is reflective of who is logged into the box. Has loginctl totally taken over or...?

Log in without lxdm and see if that makes a difference.

Yes, Logging into a tty or ssh makes me show-up in those tools.

Seems most display managers break things implement their own unique approach.

Well, if my goal is to find users logged into my box through loginctl:

loginctl --no-legend list-users | awk '{ print $2 }' | sed ':a;N;$!ba;s/\n/ /g'

Does that seem sane?

I can see why the X session wouldn't be listed if the DM does things it's own way - but once you open a virtual terminal, that session should count - I would think.

For me each 'window' in tmux under X counts as a distinct login (so I show up 4 times when I have 3 tmux windows/panes/tabs open).

Close:

loginctl --no-legend list-users | awk '{ printf "%s ",$2 }'

That ends in an odd, highlighted symbol for me:

facade love %

That's Zsh's symbol for the lack of a new line. It shouldn't be an issue if you are scripting.
