Solution in #nixos #flake for machine ThinkPad #x230 seems to be:
services.xserver.enable = true;
services.displayManager.gdm.enable = true;
services.desktopManager.gnome.enable = true;
services.desktopManager.gnome.flashback.enableMetacity = true;
# At the GDM login screen, click the gear # icon to choose between:
# - "GNOME" (Wayland)
# - "GNOME Flashback (Metacity)" #X11
and
nixos-rebuild boot + reboot is required (not switch) when jumping across major nixpkgs versions
