Far on the other side of my building at work I have several linux boxes
that displays a slide-show on a X screen. When our power blinks the
computer will reboot and is fine. The monitor (which is a flatscreen
tv) turns off and stays off until someone turns it on. From my desk I
can easily tell if the computer is up and running, but I can't find a
way to tell if the monitor is on or not. Does anyone have a way to
remotely tell if a monitor is on?
If you can ssh to the computers and run ddcprobe (in package xresprobe)
then the output should tell you if the attached monitors are on. (I am
currently not at my Linux box so I cannot try it myself.)
works on my dual head setup, but only id's one of the two
monitors. But they're attached to the same card, maybe that has
something to do with it.
get-edid has the same problem here.
to OP: might I suggest a UPS?
