Curtis, here is what Alan Snyder, a myth user uses:
----------------------------------------------------------------------------
Here's the script I use on our kitchen machine that's sometimes a TV and
sometimes a desktop. It's linked in ~/.kde/Autostart
#!/bin/bash
while true; do
if [[ `top -b -d 1 -n 3 | grep mythfrontend | awk -f ~/max.awk` == "1" ]]
then
xset -dpms s off
else
xset dpms 0 600 0 s off
fi
sleep 60
done
where max.awk is
BEGIN {
total=0.0
}
{ total=total+$9 }
END {
if (total>30) { print 1 } else { print 0 }
}
So if mythfrontend is using more than 10% CPU (noticing that top runs 3
times) then the screen power controls are disabled; otherwise there's a
10-minute timeout.
