I experience the same bug on my Thinkpad Yoga 260 with Ubuntu 16.04.2 and 4.11.7 kernel (the issue happened also on older kernels) with my Thinkpad Compact Bluetooth Keyboard with Trackpoint. The dmesg output looks like this:
[ 4952.521400] lenovo 0005:17EF:6048.0017: unknown main item tag 0x0 [ 4952.521703] input: ThinkPad Compact Bluetooth Keyboard with TrackPoint as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:17EF:6048.0017/input/input40 [ 4952.522622] lenovo 0005:17EF:6048.0017: input,hidraw3: BLUETOOTH HID v3.09 Keyboard [ThinkPad Compact Bluetooth Keyboard with TrackPoint] on a4:34:d9:45:7d:7d Would be perfect if someone has a solution, it's a very annoying bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1454450 Title: Bluetooth mouse laggy and erratic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1454450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
