I would like to test to see if the video monitors are on/off/etc.
Is anybody aware of a way to monitor the video monitor?
I've looked at read-edid ( VBE/DDC signalling), but it looks a little risky. I don't know if it is safe to call it very often for a long period of time. This does report of the monitor is turned on or off ( well, actually it reports an error when trying to read the monitors EDID block when it's power is off).
I also see that there is an x extension for dpms info, but I do not know if this queries the monitor or the xserver.
Does anybody have any other info, that would allow me to detect if a monitor is off/on/connected/err?
