I have to get nine 46" LCD monitors (running Windows) to suspend/sleep at 8pm and wake at 8am every morning. It's been a bit of a mess trying to get the commands working, including the privileges. Since I'm an Ubuntu user first and foremost, I'm wondering how easy this would be in Ubuntu/Linux.

I know cron would be able to run my suspend/sleep command at 8pm (what is the suspend/sleep command anyway?), but what about waking the machine up at 8am without using Wake-on-Lan or manual intervention?
