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