Display randomly wakes up

[Senseotech]

Running the latest Lion, I can sleep my display via a hot corner, only to have it randomly wake up with no user intervention. Its just the display, the Mac isn't set to sleep at all. The time interval isn't consistent either, it can be 5 minutes or several hours, but needless to say, its highly annoying when I myself am trying to sleep and the screen randomly cuts on for 5 minutes, goes to sleep, then wakes back up after a random amount of time, basking me in light.

I've had the exact same problem. Did you ever figure out what was happening?

No clue, but I have two theories. One being something with my BT trackpad or keyboard causing the screen to wake back up, the other relating to network traffic doing it. If it wasn't such a major pain to test them, I'd turn off each to confirm.

Hmm, well if it happens again, one thing you might want to do is look at the 'Console' application and search the system log for the time that the monitor comes back on. I've been doing this over the past week or so (I've only managed to do this a couple of times, because when it wakes me up at 4:00 AM, the last thing I want to do is debug a problem), and according to the logs it seems that the problem may either be related to time machine backups, or something connected to my iTunes that disconnects intermittently (I have my iPhone connected, a set of speakers, and sometimes a bluetooth mouse).

I'm leaning more on it being an iTunes issue, as sometimes the iTunesHelper module (which detects when an iPhone or whatever is connected and automatically opens iTunes when that happens) can be kinda buggy...

So just now I caught the screen turning on, when I looked at the console, it looks like what caused it to turn on was:


2/27/12 11:07:50.249 PM screensharingd: Authentication: FAILED :: User Name: N/A :: Viewer Address: 188.142.206.56 :: Type: VNC DES


'Viewer Address' is NOT my ip, looks like someone from Hungary. It's probably a bot trying to brute force a way in. Anyway, I turned off screen sharing, so I'll see if this has fixed my problem.
