I suspect that the reaction to HDMI event and the behavior that 
different AVRs  exhibit is where the problem lies.

Also I have notices that Rasbian Buster only requires xscreensaver to be 
installed and then disabled to work properly with my AVR. But there is 
no Power management with a RPi.

The Desktop environment is a variable here as well. Bottom line is too 
many factors are or can be involved.

screensaver, DPMS, applications, X11.

I clearly don't understand any of it, but my experiments gives me a 
solution.
