Description (last modified by jg)
While the DCON can power down the LCD on its own after a programmable delay (already being used by the DPMS code in the X server, I believe), the DCON itself consumes lots of power (several hundred
millwatts). We need to get it off when not in use after a second delay. I'm concerned about a child reading a book and forgetting
to get the screen completely off.
We need to be able to set a timeout to turn off the DCON as well, complimentary to the DCON's control of the LCD panel.
