Public bug reported:
I have a Logitech bluetooth mouse (M650) and keyboard (K380, details in
the attached log). I almost never power down the laptop: I suspend and
resume it.
Sometimes when I resume from suspend everything works flawlessly. Other
times, there's a 2-3s "freeze" after just several seconds of input
inactivity, during which moving the mouse or pressing keyboard keys
gives no response. After 2-3s, all the keys pressed during the freeze
suddenly appear on screen.
Restarting the bluetooth service, going to airplane mode and back or
turning the mouse and keyboard on and off does not help at all.
The delay makes using these input devices barely usable.
