[Desktop-packages] [Bug 1834085] Re: Bluetooth touchpad (Apple Magic Trackpad) disconnects every few minutes
The above log looks like a kernel issue (if not a hardware issue). ** Package changed: libinput (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1834085 Title: Bluetooth touchpad (Apple Magic Trackpad) disconnects every few minutes Status in linux package in Ubuntu: Incomplete 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) [ 1609.070538] magicmouse 0005:05AC:030E.0007: unknown main item tag 0x0 [ 1609.070797] input: Apple Wireless Trackpad as /devices/pci:00/: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/pci:00/: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/pci:00/: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/pci:00/: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 - Apple Wireless Trackpad: device removed de juny 13 21:37:49 TM1703 gnome-shell[5071]: g_array_unref: assertion 'array' failed de juny 13 21:37:49 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) UnloadModule: "libinput" de juny 13 21:37:49 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) systemd-logind: releasing fd for 13:80 de juny 13 21:37:49 TM1703 upowerd[1271]: unhandled action 'unbind' on /sys/devices/pci:00/:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:05AC:030E.0008 de juny 13 21:37:50 TM1703 kernel: magicmouse 0005:05AC:030E.0009: unknown main item tag 0x0 de juny 13 21:37:50 TM1703 kernel: input: Apple Wireless Trackpad as /devices/pci:00/:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:05AC:030E.0009/input/input25 de juny 13 21:37:50 TM1703 kernel: magicmouse 0005:05AC:030E.0009: input,hidraw1: BLUETOOTH HID v1.60 Mouse [Apple Wireless Trackpad] on 64:5d:86:86:3f:98 de juny 13 21:37:50 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) config/udev: Adding input device Apple Wireless Trackpad (/dev/input/mouse1) de juny 13 21:37:50 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) No input driver specified, ignoring this device. de juny 13 21:37:50 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) This device may have been added with another device file. de juny 13 21:37:50 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (II) config/udev: Adding input device Apple Wireless Trackpad (/dev/input/event16) de juny 13 21:37:50 TM1703 /usr/lib/gdm3/gdm-x-session[4882]: (**) Apple Wireless Trackpad: Applying InputClass "libinput touchpad catchall"
