I did discover that some of the required settings do not make sense. If my
system is not running mythfrontend then I can leave the power management in
Presentation mode which turns off DPMS. However, in Mythfrontend, this will
not work and I can't get mythtv to come out of blank mode. I have to do
Ctl-Alt-F1 and login to CLI and reboot.

What I have found works in all cases is Screensaver installed and disabled,
and DPMS enabled with all the timers set to Never.
