Those users are all me. In your case, they are all you. There is nothing to be concerned about.
Here’s how it works:
There a file “/var/run/utmp” which is a small database of active users and the associated terminal.
When I do a graphic login, that adds an entry (the one with the “:0” in the TTY column).
As KDE starts, it apparently allocates a pseudo-terminal (“/dev/pts3”) and adds a utmp entry for that.
I am also running Konsole, with three terminals (command line windows). There’s a utmp entry for each of those.
The “w” command is just listing “utmp” entries. A system broadcast notification will send a message for each utmp entry. So, for example, if there’s a power interruption my UPS software sends a message. I get a copy of that message in each of those three terminal screens, and I get one from the KDE notifier.
I probably should go back to using “xterm” instead of “Konsole”. With “xterm” there’s a command line option “-ut” which tells it not to write a utmp entry. On the other hand, power outages are rare enough that the annoyance level isn’t too bad.
I hope I have sufficiently explained what you are seeing, and what it is used for.

it is not two users, it is one user with two processes.

I hope not

Yes.

Thank You very much for this info!

Bad habit of using ‘guake’, my fault. This is the xterm output:

What bothers me is the two gdm, I’ve never seen it. Standard for gnome 3.6+??
I hope I have sufficiently explained what you are seeing, and what it is used for.
Now tomorrow or so, when your climate returned more or less to normall, please study these CODE tags once more. What you did now, I assume, is copy/paste of the text already posted. That does not help much to keep the layout. You can see how it should look like in nrickert’s post. You should copy/paste directly from the terminal window in between the CODE tags.
Yes, I think that’s normal. I rarely use gdm – I prefer kdm. But I do occasionally switch to gdm for testing, and I seem to recall seeing two utmp entries.
