Hi,

I'm a single user of a single KDE desktop. For some reason, with KDE I've always been logged in twice (always once, as long as my conscious act is concerned, which is my point). Today there are three of me:

$ users
llama llama llama

Is there a way to uncover the entities which keep on logging in in my name?

$ who

??

Llama · 2013-01-05 05:41:27

$ who
llama :0 2013-01-05 07:58
llama pts/0 2013-01-05 07:58 (:0)
llama pts/1 2013-01-05 07:58 (:0)

pts has something to do with remote connections. What are they in my case? None of my conscious activities, sure.

Dunno what to tell you. KDM? KDE? I use lxdm and only see one:

% who
facade  pts/0        2013-01-05 01:02 (:0.0)

flipper T · 2013-01-05 06:25:04

I use lxdm

jk[~]$ who
jk       pts/0        Jan  5 06:22 (:0)
jk       pts/1        Jan  5 06:24 (:0)
jk[~]$

[edit: only user on a laptop / wireless network]

I use a systemd service and I get nothing

flipper T · 2013-01-05 07:02:51

If it helps anyone here to diagnose the "problem", when i kill X

systemctl stop lxdm.service

and log into tty, only 1 user showing.

Restart lxdm:

jk[~]$ who
jk       tty1         Jan  5 06:59
jk       pts/0        Jan  5 07:00 (:0)

Reboot:

jk[~]$ who
jk       pts/0        Jan  5 07:24 (:0)

oh hum...

...Open 2nd terminal (I use gnome-terminal)

jk[~]$ who
jk       pts/0        Jan  5 07:24 (:0)
jk       pts/1        Jan  5 07:27 (:0)

...Open 3rd

jk[~]$ who
jk       pts/0        Jan  5 07:24 (:0)
jk       pts/1        Jan  5 07:27 (:0)
jk       pts/2        Jan  5 07:27 (:0)

closing a terminal reduces number of user by 1

So mystery solved for me, hope it helps OP.

Interesting that gnome-terminal opens as a login shell. Makes me wonder if this occurs with other terminal emulators. Can you try others?

flipper T · 2013-01-05 08:15:04

Exactly same behavior with lxterminal.

I use i3wm, if that is of any relevance (not sure why it would be)

No it isn't. What I am trying to say is that typically when you open a terminal (at least this is what I have experienced), it is not a login shell. A login shell starts up slightly differently, configuration wise, and usually happens when you log in (imagine that!).

You can achieve a login by issuing something like

$ bash -l

or

$ zsh -l

if you prefer.

I am not so familiar with vte terminals though, so I am not sure if it has to do with that, or possibly the settings within those terminals.

Both KDE konsole and xterm do the same, and i'm not using a display manager.

IIRC it's an option in gnome-terminal

No, "pts/X" are pseudo ttys which are open when you use a terminal emulator (and of course remote sessions as well). The reason why you see multiple logged in users is because your konsole (you use KDE, right?) updates utmp entry. You need to scout its config to set the corresponding setting to false.

nomorewindows · 2013-01-15 23:00:29

Every time a terminal is open, it opens a new user shell, but some of the actual logging in that would be redundant doesn't have to be done over and over again.

cfr · 2013-01-15 23:44:50

There are twelve of me.

I can't see an easy way to prevent this in Konsole's config...

Shark · 2013-01-16 09:56:27

I have KDE with KDM (i am using zsh). When i open a konsole i get the same output as previous posts:

saso     :0           2013-01-16 10:45
saso     pts/0        2013-01-16 10:45 (:0)
saso     pts/1        2013-01-16 10:55 (:0)
