xbmc ACPI suspend with xmbc running on a mythtv-backend?

Does anyone use ACPI suspend with xmbc running on a mythtv-backend?

I currently have mythfrontend setup so that when it exits I get back to mythwelcome and mythbackend then will run a mythsuspend script to do suspend to RAM.
The important thing though is that it programs my RTC clock so that it wakes up in time for the next recording schedule.

I'm removing mythfrontend and running xbmc instead as a frontend, but I'm going to guess that if I just use XBMC's suspend feature, it will just suspend and my PC will not wake up for its next recording.

How does one do ACPI suspend with xbmc on a PC that is also running a myth backend?

Thanks,
Marc

I dont have a combined back/frontend but I use a backend with with acpi suspend and rtc wakeup. You can have mythbackend run a script that will run a few checks (for downloads/used shares/certain programs) and if there is no output from the commands within the script myth-backend suspends the machine. Here is the script I use, which I found on these forums somewhere so it contains an command to check if xbmc is running.

Code:

cat /usr/bin/mythshutdown-check.sh                                                              

#!/bin/bash

mythshutdown --check > /dev/null

if [ "$?" -ne "0" ]; then

        mythshutdown --status > /dev/null

echo "Cannot suspend as mythbackend is not idle: status = '`echo $?`'"

echo         0 - Idle

echo         1 - Transcoding

echo         2 - Commercial Flagging

echo         4 - Grabbing EPG data

echo         8 - Recording - only valid if flag is 1

echo        16 - Locked

echo        32 - Jobs running or pending

echo        48 - Possibly 16 + 32

echo        64 - In a daily wakeup/shutdown period

echo       128 - Less than 30 minutes to next wakeup period

echo       255 - Setup is running

# TODO: List out the appropriate error message.

#-s/--status         (returns a code indicating the current status)

#         0 - Idle

Ive made some changes and have commented out what Im not using. Im thinking you could have xbmc exit on pressing the power button and automatically after X minutes of idle. I know myth-welcome can detect if a machine has been woken for a recording or by a user and launch the frontend based on that, but I think that a mythtv frontend wont shutdown automatically (I could be wrong, Ive just begun setting up a be/fe machine for my parents) so I dont know if theres much point trying to integrate xbmc into mythwelcome, just have xbmc launched on resume and close after X mins idle.

Thanks for your tips, they are quite helpful.

In my case, I have an edge: when I shut off my TV/receiver, I can have that send a command to my HTPC, so it can suspend based on that.

Cheers,
Marc
