I am having the same problem and would love some feedback as well. It's eating the battery alive - mine is set to 1 minute but doesn't time out. I'm wondering if we downloaded an app that may have screwed up the setting? I am coming from a BB Storm and I like the Droid X alot but I also liked have one place to control the default settings of the phone. :-( Mine worked at first but I noticed today it dims but doesn't go black. Thanks! :motdroidvert:
I was having the same issue until after I read this post- I erased a live wallpaper app called "Lightning" that I wasn't even using, but apparently it was causing the screen to stay on even though my phone was set to 2 minute timeout.
First of all DO NOT download a task killer. They are trouble makers and are not needed with the Android OS. They cause a lot of issues for the Droids. So if you have a task killer, get rid of it.
As for figuring out which app is causing the phone not to sleep, I would suggest you think about which apps you installed around the time you noticed the phone not sleeping. Then start by deleting the apps one by one. In between deleting apps see if the phone will go to sleep. (BTW does the phone go to sleep when you hit the power button??)
