<br><br><a href="http://www.mythtv.org/wiki/index.php/Mythwelcome">http://www.mythtv.org/wiki/index.php/Mythwelcome</a></blockquote><div><br></div></div>Ma,<br><br>Do you use MythWelcome with /proc/acpi/alarm? I know it's designed to work with nvram-wakeup but supposedly it can work with /proc/acpi/alarm as well.
<br><br>This morning I followed the instructions on the guide Andrew linked (<a href="https://help.ubuntu.com/community/MythTV/Install/WhatNext/ACPIWake">https://help.ubuntu.com/community/MythTV/Install/WhatNext/ACPIWake</a>
) and I looked at the MythWelcome wiki page as well, but between the two I think I got confused somewhere as to what needs to be set to make it actually go to sleep.<br><br>I know /proc/acpi/alarm works because I can set the alarm, shut the machine down and it wakes backup. What doesn't work is having Myth detect that it's not in use and shut itself down. So given that the machine is question is a slave backend that has my only tuner card but is nevertheless rarely used for recording or watching live TV (I have a lot of digital tuners for live TV watching without PVR capabilities) and given that I've got MythWelcome running on startup so that Mythfrontend does not prevent the slave backend from shutting down, here are my questions:
<br><br>1. What command do I need to use in mythtv-setup and/or mythwelcome --setup in order to make my slave backend shut down when idle (for 15 minutes lets say)? Right now it's "/sbin/poweroff" in MythWelcome and "" in the Myth backend's "Server Halt Command" is "halt".
<br><br>2. What happens if the server is idle and there are no programs scheduled? Will it simply shutdown without a wake-up time?<br><br>3. If this slave backend shuts down with a wake up time of 1 hour to record a show at that time, and in the meantime (from another frontend) the master backend is told to record a show in 10 minutes, I presume the slave backend (the only one with the tuner card) will not wake up in time to record because at the moment it has now WOL ability enabled and it would only wake at the scheduled 1 hour time or if I walked up to it and turned it on, correct?
<br><br>3a. Will WOL and ACPI/shutdown work together? Does anyone here have that configuration?<br><br>Ideally I'm working toward a set-up wherein the standalone frontends (such as a HTPC in the living room) would go into a suspend mode when not in use (by direct user action to suspend/unsuspend), the slave backend(s) would shut down when not in use, but be able to be forced awake with WOL if a user suddenly demanded to begin recording now, and the master backend would stay running all the time to service all the frontends and wake the sleeping slave backends up (as well as perform commflagging as necessary). I don't suppose anyone already has that set up?
<br><br>Thanks,<br>Brion<br>
