I am thinking of building a myth tv system. I want to hibernate my computer when it is not in use but wake up when it needs to start recording or to use the box. Are there any programs or facilities that allow this?
I don't think a software solution is possible. You probably need some kind of timer hardware that can issue the necessary wake-up inducing signals. A conventional desktop (or laptop) system that is hibernating is basically shut down. All the state required to reawaken it has been migrated to mass storage. Awakening from hibernation is more like a full startup except that instead of creating a system context from scratch by loading the kernel and init (as is done when rebooting), the system re-establishes the state that was in effect when hibernation began.
But there are exceptions: "wake on lan" ethernet cards. The card has to be powered, at least, and I'm not sure if it will work with disk hypernation, or only with suspended to memory mode. An alternative, is to connect a wake up line to the other computer, having a binary outuput card close a relay in parallel with power on switch - the normal power on/off button doesn't really disconnect the power, you know, so this would not be handling mains current.
I'd look for a mainboard and / or BIOSes that has a programmable wake-up timer.
I wonder if there could be a way to program this from inside Linux? - -- Cheers, Carlos E.
