Greetings folks,

Running Debian testing. Why do I appear to be logged in twice? This is a recent development. GKRellm used to show 1 users. Searching comes up with two likely looking posts, but it's on stack exchange and there's a cookie dialog that I cannot close so I can't read the posts.
[edit] Actually I was able to scroll line by line and the posts were no help. [/edit]


If I go to a terminal and enter who it shows me on seat0 and tty2.

Thanks in advance for any suggestions.

Try running the "w" command, then post the output here. See man w for more.

Running the w command as requested

Thanks,
glenn

if I need to guess you logged in only once, using seat0, and opened a terminal, that is tty2.
probably this helps: https://wiki.archlinux.org/title/Xorg_multiseat

Huh ... I guess, in all these years, "I never tried all the letters." I didn't until today know about "w." (Presumed synonyms for it, yes.)

To tell the truth, I didn't know about w until yesterday, when I did a web search for something like "how to list logged in users linux."

And I want to thank pan64 for interpreting your findings for me!

this is from the old days when short (two-letter) commands were invented (like vi, ex, ls, cd...), when typing grep and find were extremely tiresome. This was the time when the who command was shortened to w. Today they are not the same, they are just very similar. who w. Anyway, that was another century.

Do you have USB plugged in or any graphics device used ?

No, no USB or graphics device.

Thanks,

loginctl << run this command what's the output?

Seat0 is the default seat in Linux. It is the seat that is used when you first boot your system. The login screen is displayed on tty1, and the graphical user interface (GUI) is displayed on tty2.
TTY2 is the second terminal associated with seat0. It is typically used for running command-line programs.

TTY stands for "teletypewriter."

Then it's good nothing to worry about. and if you type: w

I believe tty2 will be there also since you opened a terminal

If you type loginctl and you see other peoples name that you don't recognize then you need to unplugged the cable quickly or disable the wireless

Do you have any other question? If not you might want to mark the thread solved. Also if you want to say thanks just click on yes.

In the early Unix days every login was a terminal (tty1, tty2, ...).
The login process added an entry to the utmp file.
The commands w and who query the utmp file, and could be used to show the logged in users.

A graphical desktop login does not have a terminal. Nevertheless it should make a utmp entry (X-based desktops used :0 :1 etc.). Every terminal/shell opened from the desktop should make a utmp entry as well (tty1, tty2, ...).
utmp does not really distinguish between a first system access and subsequent terminals.
systemd solves it by creating a user session for each system access (seat0, seat1, ...).
Now the loginctl command shows the logged in users.
