Your original post indicates failure to powerup at the appropriate time.
Attached is the script autowakeuptest.sh I use to test wakeup on xubuntu
systems (16.04 and up), it saves copy and paste from the Mythtv ACPI
wiki page.
Just make it executable (chmod +x) and run it. If it does not powerup in
5 minutes that problem needs to be fixed.
I have also attached an alternative script (autowakeuptest2.sh) which
uses rtcwake instead.
If you want to use rtcwake with mythtv you need to modify script in
/usr/bin/setwakeup.sh as follows:
replace lines
echo 0 > /sys/class/rtc/rtc0/wakealarm #this clears your alarm.
echo $1 > /sys/class/rtc/rtc0/wakealarm #this writes your alarm
with one line
sudo /usr/sbin/rtcwake --mode no -t $1
Note: "--mode no" not "-mode no" (the Mythtv ACPI wiki has a missing -
character in the example /usr/sbin/rtcwake -mode no)
