Logins via X used to update it as well (seldomly used nowadays). The local
desktop session usually updates utmp as well, at least with XFCE on
Debian/testing this is still the case. GNOME Terminal updates utmp as well.
Screen updates it, too. When I last looked at it, Konsole (from KDE) did
not update utmp.

Linda A. Walsh noticed a similar thing:

Of course this is most likely caused by changes outside of coreutils. On a
"desktop" system without any terminal windows, the desktop session should
be shown in the "who" output. On all systems I could easily check that is
the case. I do not have any SystemD/GNOME or KDE systems to test.

Thanks,
Erik
