    Since some days my display will go to sleep when pressing ctrl cmd eject keys. BUT is wakes up after just 5-15 seconds.

    Restarted and did a repairing disk permissions. Not yet done resetting PRAM, and resetting the SMC.

    How to solve this??? Any tips/suggestions?

    Any suggestions????:):)

    Did find: http://mactips.dwhoard.com/mactips/system/display-sleep not reallly solution.

    Did PRAM and SMC reset, no effect.

    Is there a syslog command to find out what caused the wake up of the display? (not the machine)
    syslog |grep -i "Wake reason ="

    Any advice??:)

    Found this link: https://discussions.apple.com/thread/3191631?start=0&tstart=0

    But do not see which kernel is the problem:
    Under System profiler all seems fine:
    P.S. the screensaver does stay on - so whatever is waking the sleep display isn't disturbing the screen saver!

    In the console I cannot find to much; I'm not an expert. Only see:
    coming back often.

    Found a work-around: when I put the display sleeping time to never I can manually put the screen to sleep and it will not wake up!! Thats fine for the moment. :):)

    So the conclusion must be that the problem is within the mechanism of display sleeping and not that some other program or process is waking up the sleeping screen. How can I update or validate that process?

    Any suggestions????
