This last time I notice that the Bluetooth Setup Assistant is running . . . and running . . . and running. So, I rebooted and unchecked to check for a keyboard or mouse if one is not attached. It's a MacBook Pro, it always has both attached. We'll see if this solves it.

With El Capitan, after the machine goes to sleep, only the Thunderbolt display wakes up. I have tried playing with the dual display settings, e.g. set the monitors to mirror mode, but no joy. I have to restart to get the macbook pro's display to work again.
