[Bug 1874713] [NEW] Instabilities when returning from idle mode and delay when detecting bluetooth peripherals

[Edson T. Marques]

Public bug reported:

I have noticed instabilities in my bluetooth, mouse and keyboard, whenever I return to my desk I go back to using my notebook that went into idle mode. In addition, I realize that when turning on the computer and entering the Ubuntu login interface, there is a relevant delay before the bluetooth peripherals (mouse and keyboard) are detected. The time difference is very relevant compared to what happened at Eoan.
Whenever I leave the idle mode, the mouse pointer became slow, with unstable and heavy movements. The keyboard also has erratic and strange functioning.
I have an old sony vaio notebook and use a wireless keyboard and mouse communicating directly with the notebook's bluetooth without the need for adapters (dongle). The Mouse is an original sony vaio that I bought with the notebook, the keyboard, unlike, was recently purchased.
For now the workaround solution I've been applying is to turn bluetooth off and on again, through the gnome configuration panel. In fact, whenever I do this, there is again a long delay before the peripherals are detected. I need to keep moving the mouse for about 10 to 20 seconds for detection to occur. I need to type on the keyboard many times until detection occurs.
