i checked the console for entries and there i see a lot of events from little snitch, it tickers trough!


then i checked the little snitch logo above, it was gone. so i tried a reinstall of little snitch (with reboot). After this, the imac / lion went to sleep.


greetings

Yes I just realized the problem myself. I have a late 2008 MacBook Pro that's hooked up to a second monitor. With Snow leopard, my Macbook would sleep without problems while the second monitor would fade to black. Now with Lion, if I close the lid to sleep, my desktop jumps to the second monitor and stays awake. Odd....

Same thing here and I will say it's a Lion issue. I did a fresh install of Lion booting from USB drive. Erased the HD and completely started a new install. No TM restore, no Archive install. Clean as clean is going to get. Created the first account after install. First thing I did was go into Energy Saver and set Computer Sleep and Display Sleep to 1 min and let it set. The screen turned off but the mac never went to sleep after letting it set there for 15 mins. So consiedering this as a freash install with no user configration there's a problem with it. I have 2 late model C2D Macbook and MacBook Pro both are having different Sleep issues. Macbook won't sleep and MacBookPro sometimes won't come out of sleep. Then I also have a new i5 MacbookPro that seems to be fine and a brand new 5 day old iMac that also seems to be fine. So maybe it's a older hardware related issue. Maybe Core 2 Duals are having the issue. ???
