Displays won't automatically sleep since Mavericks upgrade

[thirdkind]

I have a 2010 MacBook Pro that has been running pretty well since upgrading to Mavericks. However, neither the MacBook's display nor my external display will go to sleep on their own. I've tried changing the display sleep timer to different values, restarting, etc. I wasn't having any issues prior to the upgrade. System sleep works fine if I force it, though.

Anybody else have sleep issues?

Apparently I'm the only one

A PRAM reset appears to have fixed the issue, if anyone is curious. Probably should have tried that to begin with. Also seems to have fixed a randomly occurring lockup/beachball I was getting at the login screen immediately after booting.

I'm having the same issue.

Screensaver is set for 5 minutes, sleep is set for 10. Screensaver turns on but when it's about to sleep both displays go black and then turn back to the screensaver.

Displays will sleep if I set them to sleep before the screensaver goes on.

I've done a clean install and I still am having this problem.
