I'm having a weird phenomenon happening to me and I can't seem to figure it out. Every night for the past week or two, my monitor (Sony Bravia TV) has been shutting itself off between 3:30AM and 4:00AM. I JUST caught it doing it this time at 3:41AM, and it only happens during this time.
At first it felt like the TV was dying, but given that it ONLY happens at a specific time tells me that there's a setting somewhere. I haven't duplicated the issue outside of being on my computer, so I guess I'll have to pick a night and try it out watching TV or playing a console to rule out a bad TV and/or TV setting.
My hunch tells me that there's a setting in Ubuntu that's triggering it to shut off. I have XScreensaver, but it's disabled at the moment, as well as Caffeine (which SHOULD have prevented this from happening). GNOME power settings are set to "Never", so I'm at a loss? Has anyone ran into something like this before?
