Re: Cron incomplete performance in UbuntuPhone

 

Hi,

you can use powerd-cli to schedule a wakeup at 7am.

checkout powerd-cli --help. There is an option to schedule a device
wakup n seconds from now. Not sure how reliably that works in
combination with a cron job... but well, play around with it.
