Couldn't find a thread for this (it's probably already been mentioned though) When you're in sleep, the only way to bring Lion back is by actually hitting a physical key. But when you're Mac dims down and turns the display off (before it sleeps, if you have it set to do that) I always brushed my trackpad on my MBP and it would undim the screen and I could continue working, I much preferred this way it seems nicer. On Lion it makes you hit a key to undim the screen, simply brushing the trackpad does nothing to the Mac. Has anyone found a solution for this (I might be missing a pref) but I can't find anything! Slightly annoying but not a major issue.
