If you think something is actually running and the monitor's in some
power-saving state, you can use "ddccontrol" to change the power-saving
state. Here's how I turn each monitor off and on in turn (in sh):
alltext="$("$DDC" -p 2>/dev/null | sed -n /Detected/,/^Reading/p)"
devices="$(echo "$alltext" | grep '^ - D' | cut -f 4 -d ' ')"
for device in $devices ; do
echo -n '-=>' $device
echo " ($(echo "$alltext" | grep -A 3 "$device" | grep 'Monitor Name' \
| cut -f 2 -d : | colrm 1 1)) <=-"
for state in off on ; do
case $state in
off) ddcstate=5 ;;
on) sleep $sleeptime # this assumes this happens last
ddcstate=1
esac
echo -n "$state "
"$DDC" -r 0xd6 -w $ddcstate "$device" > /dev/null 2>&1
done # for state
echo
done # for device
There are probably better ways to do it. One of my monitors is pretty slow,
which is why sleeptime is as high as it is. Adjust to taste.
If nothing is happening, this won't help. But OTOH it probably won't hurt
either.
