Thanks Jakub,

  I have tried:

# setterm -blank 1
# setterm -powerdown 1
# setterm -powersave hsync     (waited - did not poweroff moniter, just blanked)
# setterm -powersave powerdown (same thing - no poweroff)


  So I am at a loss as to how it worked on the first boot and now no longer
worked. I read:

https://wiki.archlinux.org/index.php/Display_Power_Management_Signaling#DPMS_interaction_in_a_Linux_console_with_setterm

http://webpages.charter.net/dperr/dpms.htm

and so far I have not found a way to repeat the poweroff that worked on first boot.

I did install the nvidia package for future use, which pulled in xorg-server as
a dependency, but X is not started. I don't see why that would influence console
behavior.

If anybody has any additional information, I thank you in advance.
