Well that's a no-go, because when you de-power the monitors, ddccontrol gives you no info about what sleep state they're in. Reasonable, I guess.
Perhaps there is a command to put the monitor in standby state instead of power off. Maybe it is possible detect switched off state by reading some file in /sys.
You still mix monitor and system issues. E.g. a media player may inhibit power saving for monitors. I have seen that sometimes suspend to disk (hibernate) is blocked, but I do not know details. An obvious reason is full swap, so RAM can not be saved there. Perhaps suspend to RAM may be blocked as well.
There wasn't room on the hard drive to just enlarge the old one without spending a lot of time moving partitions around. Some time then or after, automatic suspension stopped working. Do I have to tell something the UUID of the new swap partition, or does it figure it out?
Update grub and initramfs configuration.
