Title:
  Bluetooth touchpad (Apple Magic Trackpad) disconnects every few
  minutes

Status in Linux:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I recently got an Apple's Magic Trackpad. I paired it with Ubuntu
  18.04.2 LTS and worked out of the box, no special drivers needed.

  However, I experience frequent disconnections that last a few seconds
  (5-15 seconds usually), which are quite annoying, as the cursor stops
  responding during that interval. The trackpad connects by itself after
  that period. That usually happens every 20-40 minutes.

  I use the onboard bluetooth device of my laptop. I also have, at the
  same time, two more bluetooth devices (keyboard and mouse) and they do
  not experience that issue, just the trackpad. On ocassion I use
  bluetooth headphones which work just fine.

  First of all:

  Using the command "bluetoothctl" I get the following every time I
  experience a disconnection:

  [CHG] Device F4:1B:A1:33:F9:8D Connected: no
  [CHG] Device F4:1B:A1:33:F9:8D Connected: yes

  Checking "dmesg" I can see more information: (if I am not mistaken,
  this shows 4 disconnections)
