  Isn't that the whole point of excercise?  If I want to turn off the
display, I want to turn off the display.  BTW, I've discovered a problem.

sleep 1 && xset -display :0.0 dpms force off

...allows to bring back the display by tapping any key.  I prefer
{SHIFT} because it doesn't do anything by itself.  But the command...

setterm --blank force

...can't be awoken from in a text console.  However, if X is running in
tty7, I can {CTRL}{ALT}{F7} and X comes up.  Then I can {CTRL}{ALT}{F1}
to get back to a text console in tty1... weird.
