    Noticed today the display on my MBP won't sleep; this is what I've done/tried thus far:

    - Gone though my programs and none of them seem to be the culprit.
    - Quitting every app and leaving the computer idle with nothing running, display still doesn't sleep.
    - Double checked system preferences and made sure nothings conflicting.
    - Also of note, the screen saver will trigger and work fine.
    - Permissions repair did nothing

    Any idea's?

    I always thought the screen saver and the display sleep were on the same timer. That is, if the screen saver timer is engaging, then the display sleep should also engage. Is there some specific action that can keep the display awake but not cancel the screen saver?

    I would create a new user and test there. Maybe you have a background process running that's causing this... I can confirm that my display sleeps properly (15" i7)

    Do you have Steam installed? I've noticed some strange behavior with display/system sleep since I installed Steam. After testing things, it appears that sleep gets broken after you run any game in Steam. The only remedy I've discovered is a reboot.

    I have the same issue and I can confirm its Steams fault.
    Pretty annoying.
