Acabei de comprar um Apple Magic Trackpad 1 e o conectei ao meu sistema Ubuntu 15.10 (agora 16.04). Tudo funcionou perfeitamente.

Uma vez conectado, o trackpad "para de funcionar" a cada poucos minutos. Não sei se está sendo desconectado do Bluetooth ou se está desligando. Tudo o que sei é que posso fazê-lo funcionar novamente pressionando o botão liga / desliga no trackpad. Às vezes eu tenho que fazer isso duas ou até três vezes, mas depois vai funcionar de novo.

Eu tentei as coisas normais, como trocar as baterias, excluí-las do bluetooth e adicioná-las novamente. reinicializando meu sistema e adicionando-o novamente.

Se eu deixar o dispositivo conectado durante a noite, quando eu voltar para ele de manhã, tocar no trackpad despertará o sistema.

Desempenho de servidor de mosaico aparentemente inconsistente com o lançamento do SSH vs lançamento 'local' A janela do Android Studio no Ubuntu é muito grande

score 0 · Answer 1

Pode ajudar a examinar a saída de journalctl -u bluetooth.service

Eu tive problemas com o módulo bluetooth no meu Lenovo Thinkpad Yoga (executando 15.10 - > 16.04) conectando ao meu alto-falante Bose Soundlink Color depois de acordar da suspensão, assim como alguns outros problemas como atraso e perda de áudio. Eu peguei um adaptador bluetooth usb que suportou mais alguns recursos conjuntos que foram incorporados no bluetooth desde que meu laptop foi produzido e funciona muito bem. A comunicação bluetooth está entre o adaptador e o alto-falante e o Ubuntu o vê como um dispositivo USB.

Eu tive seu mesmo problema no Ubuntu 18. Sua saída strace é semelhante à que eu vi na minha máquina. Corrigi o meu problema ao desativar a suspensão automática do USB .

Eu estava deixando o módulo do kernel manipular o HIDP (acho que você pode verificar isso indo até /etc/bluetooth/input.conf e verificando que UserspaceHID não está definido como true ) e, por padrão, o kernel suspenderia automaticamente dispositivos usb não está em uso para economizar energia. E aparentemente esse comportamento estava causando estragos no meu trackpad mágico.

Esse comportamento pareceu aparecer na saída de sudo btmon . Eu podia ver o HCI enviando um comando para sair do modo sniff (também conhecido como modo de economia de energia?). Às vezes saía com sucesso, fazendo a transição para o modo ativo e se reconectando ao trackpad. Às vezes não, e eu veria:

> HCI Event: Mode Change (0x14) plen 6                                                                                                                               #10952 [hci0] 807.142497
        Status: Connection Timeout (0x08)
        Handle: 256
        Mode: Active (0x00)
        Interval: 0.000 msec (0x0000)

E então o trackpad parava de funcionar enquanto a conexão era restabelecida. Depois de desabilitar a suspensão automática do usb, ele sempre fica no modo ativo, evitando quaisquer problemas causados pelo modo de entrar / sair do sniff.

Uma coisa que o artigo do arch-wiki ignora é como encontrar o dispositivo bluetooth correto na saída de lsusb . Talvez fosse óbvio para alguns, mas não para mim. Portanto, certifique-se de executar lsusb -v ou use usb-devices para obter mais detalhes que facilitam a identificação do dispositivo desejado.

Eu sei que essa pergunta é antiga e eu admito que não entendo totalmente todos os elementos desse problema, mas espero que alguém ache essa resposta útil.
