I began experiencing this recently on 16.04 where it had been working
previously: When resuming from suspend both the Bluetooth mouse and
keyboard would not reconnect when I began using them.
I eventually traced it to a change I'd made in the GUI - I'd changed the
Visibility (Discoverable) setting from "Always" to "Temporarily - 3
minutes".
In this case "systemctl restart bluetooth" service didn't help, but
sometimes using "bluetoothctl" and then "power on" and "discoverable
yes" would (eventually) kick it into life. Sometimes I'd also need to
force a connection to one of the devices from the PC ("devices" then
"connect <MAC-ADDRESS>" [ tab-completion works for MAC]) - good job the
laptop has a built-in PS/2 keyboard.

Title:
Bluetooth mouse fails to re-connect after sleep.
Status in bluez package in Ubuntu:
Confirmed
Bug description:
This exact harware was working faultlessly in 13.04. Since re-
installing at 13.10 the mouse consistently failes to reconnect after
the device either hybernates or ever goes to screen saver sleep.
I have to remove the dive and re-add it each time (which works well).
There are other issues with the bluetooth stack as well in that I have
not found any way to use bluetooth tethering to my mobile which again
worked well and was easy to configure in 13.04
Peter.
