Long ago, I remember putting something like:

xset dpms off (or something close - man xset, and you can run it from
a terminal to test)

into my ..xinitrc file to force my monitor to stay on..  That was
10years ago though, and flaky (new) dpms was giving me grief -
resetting my monitor calibration every time it would kick in..  same
rules apply today as far as xset goes though..
