>Also note that just logging out from the current session makes the bluetooth mouse work again immediately.

I am seeing this behavior as well.

The mouse works as expected prior to suspending/resuming. Then, the pairing light on the mouse shows that it is connected and dmesg confirms this, however the only way to get input is by logging out and back in, or restarting the computer.

I'd be happy to post logs if that would be helpful
