Which, since I've not had to run startx in at least 10 years, will take
some studying to get it right. Up to now, the DM of the week has always
started X.
Now some additional data. I've made several xset attempts to kill both
dpms and the blanker, without the expected success. However if I think
in terms of blanker, I note the konsoles it hides by blanking the
screen, are still there if I can get the pw to work.
What sort of a clue is that?, and how can I disable dpms since it appears
that xset -dpms per the man page is ignored.
