Still unable to get SDDM to come up when the ethernet cable is connected to 
the USB NIC adaptor dongle.  :-(

I added "rc_start_wait=500" in '/etc/conf.d/display-manager' just in case 
delaying SDDM would allow it to launch without any interference from the 
network configuration and start up, but it made no difference.  The only way for 
SDDM to launch successfully is to make sure the ethernet cable is unplugged 
from the USB NIC adaptor at boot, or to use a different NIC.

Is there something which might explain this behaviour?  :-/
