I don't either.

First thing you can do is look for a file like /etc/pam.d/gdm3 (or possibly
/etc/pam.d/gdm), and see if it contains the pam_limits.so line.  If
it doesn't, then you know it isn't reading /etc/security/limits.conf
file, and your first step would be to add the pam_limits.so line.
VERY carefully, after reading all of the PAM documentation.

If it does contain this line, then perhaps you can try running a standard
Debian X session instead of a GNOME session.  Pick your favorite regular
window manager that is NOT part of a desktop environment, put that in
your ~/.xsession file, login with a Debian session, open a terminal, and
see if the limits are correct.  Then remove the ~/.xsession file (or
restore it to whatever it was before) to go back to the way things were
before, if you still want to.

If the limits are correct in a terminal executed by a regular window
manager inside a Debian session, then you know the PAM stuff is working
correctly.  If they're NOT correct inside a terminal executed by dbus
inside a GNOME session, then you have some more digging to do.  It's
possible that they're working just fine in other pieces of your GNOME
session, just not in terminals.  It's possible that you may or may not
care about terminals, or that you may or may not care ONLY about terminals.
You're not exactly giving us much detail here.
