GDM normally uses systemd to get the system keyboard configuration when available. If not, GDM will use the X configuration. However, the non-systemd GNOME profile on Gentoo defaults to OpenRC and Wayland, so none of this may work. GDM will then use a default keyboard, which will make it difficult to type a password if this is not a desired layout.
