You will have set up that multi-screen configuration as *your* settings.
The login manager has its own.

In the past (on older versions of Gnome, that I have used), if I located
my monitors.xml file (on this OS at /home/tim/.config/monitors.xml), I
could copy it into the home space of GDM (the login manage for my old
OS), which was: /var/lib/gdm/.config/monitors.xml

I mention *my* *old* installations, because I don't know if the current
ones do the same thing in the same way, but I'd guess something similar.
Look for your monitors.xml file.  Find the homespace for your login
display manager.

[tim@paralytic ~]$ locate monitors.xml
/home/tim/.config/monitors.xml

[root@paralytic ~]# grep gdm /etc/passwd
gdm:x:42:42::/var/lib/gdm:/sbin/nologin

[root@paralytic ~]#cp /home/tim/.config/monitors.xml /var/lib/gdm/.config/

And, for good measure, if this is the solution for you.  You can also
copy the xml file into /etc/skel/.config/ so that any newly created
users will get the monitors.xml file put into their homespace as their
account is set up.



That seems to have done it, thanks for the guidance.

I found that making the laptop screen be on the right in Xfce Display
settings, it forces the login to the external monitor. It appears that
the left monitor is the primary here.

No guarantees, but you can try adding i915.panel_ignore_lid=0 to your
kernel command line.  (This works on my T430s with KDM and Plasma.)
