Linuxcnc has neveer called anything like that directly. But it is 
launched by mostly python scripts that could be edited to add it.
And I finally got enough of the xfce4-goodies installed to get the 
ability to control it via the settings menu, and have successfully 
turned it all off.

It turns out that the color cycling screen was that old 17" 4x3 Dell lcd 
monitors response to the synch drop that shuts most modern monitors off.

The fly in the login soup was that particular login greeters total 
non-indication that a passwd was being entered. That keyboard has a 
custom fitted swarf cover that makes error free typeing a much sought 
after endeavor and I never write code using it, but punching it in one 
character at time rather violently seems to work. Since I am normally 
alone, that advertising of the passwd is a non-worry. I've taken to 
locking up at night, along with some signage promising response to 
prowlers in lead, should take care of the security if they can read...

Thanks Alan.
