Bluetooth long delay while connecting keyboards before unlocking

[linconbb]

What Happened?

When trying to connect to Bluetooth keyboards on the lock page on OS 8 RC, it will turn to stun immediately after the device being connected, and you need to wait for few minutes to wait it works normally. Besides, system is unable to connect keyboards automatically after awaking from sleep or suspend. Thus, I must reopen the BL keyboard into pairing mode to connect to system unless it will show "Cannot connect".

Steps to Reproduce

1.Turn on the Computer.
2.Connect the BL keyboard while on the lock screen.
3.Long time to wait until it works normally.

Expected Behavior

1. A Bluetooth device is available to connect automatically after rebooting or awaking, but it does not.
2. Connect to BL device on lock screen takes up too much time.
