Same issue on Ubuntu 20.04 5.11.0 with an Apple Magic Trackpad on an AMD desktop machine. My Apple Bluetooth keyboard works great - no issues with any disconnections. The Apple Magic Trackpad will glitch typically when there is some significant CPU load. The glitch will either disconnect the trackpad entirely, or it reconnects after 10 to 60 seconds but usually in a state where the normal tap is registered as a secondary click. The trackpad works great with my Apple laptop so this is not a hardware issue.

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) [ 1609.070538] magicmouse 0005:05AC:030E.0007: unknown main item tag 0x0 [ 1609.070797] input: Apple Wireless Trackpad as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:05AC:030E.0007/input/input23 [ 1609.071460] magicmouse 0005:05AC:030E.0007: input,hidraw1: BLUETOOTH HID v1.60 Mouse [Apple Wireless Trackpad] on 64:5d:86:86:3f:98 [ 1676.917377] NET: Registered protocol family 38 [ 1872.815348] magicmouse 0005:05AC:030E.0008: unknown main item tag 0x0 [ 1872.815559] input: Apple Wireless Trackpad as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:05AC:030E.0008/input/input24 [ 1872.816248] magicmouse 0005:05AC:030E.0008: input,hidraw1: BLUETOOTH HID v1.60 Mouse [Apple Wireless Trackpad] on 64:5d:86:86:3f:98 [ 3101.682671] magicmouse 0005:05AC:030E.0009: unknown main item tag 0x0 [ 3101.683100] input: Apple Wireless Trackpad as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:05AC:030E.0009/input/input25 [ 3101.683673] magicmouse 0005:05AC:030E.0009: input,hidraw1: BLUETOOTH HID v1.60 Mouse [Apple Wireless Trackpad] on 64:5d:86:86:3f:98 [ 3110.683360] magicmouse 0005:05AC:030E.000A: unknown main item tag 0x0 [ 3110.683929] input: Apple Wireless Trackpad as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:1024/0005:05AC:030E.000A/input/input26 [ 3110.684487] magicmouse 0005:05AC:030E.000A: input,hidraw1: BLUETOOTH HID v1.60 Mouse [Apple Wireless Trackpad] on 64:5d:86:86:3f:98 And this is what journalctl -b shows at the moment of the disconnection/reconnection: de juny 13 21:37:49 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) config/udev: removing device Apple Wireless Trackpad de juny 13 21:37:49 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (**) Option "fd" "64" (1,63 m)˜ de juny 13 21:37:49 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) event16 -
