Teclado da Apple a1016, o emparelhamento falha

Question

Não consigo emparelhar um teclado Apple sem fio a1016 com meu laptop Dell XPS que executa o Ubuntu 17.10.

Eu vi esses tópicos, instruções deles não ajudam no meu caso: Par Teclado Sem Fio da Apple 3ª geração com o Ubuntu 16.04? e O Apple Wireless Keyboard não se conecta 15.10

Eu tentei por meio da GUI de configurações do sistema, onde o dispositivo está listado como "Não configurado". Eu clico nele, então às vezes, depois de pressionar um botão no teclado bluetooth, eu recebo a janela de solicitação de PIN. Eu digito o PIN solicitado e depois Enter, mas nada acontece (na maioria das vezes) ou a janela é atualizada e um novo PIN é solicitado.

Eu também tentei via terminal (prompt de comando bluetoothctl), tentei confiar no dispositivo e depois conectar / parear, sem qualquer sorte. O erro é ConnectionFailed ou AuthenticationTimeout. Tentei com o pacote blueman, que parece ser uma GUI para bluetoothctl. Sem sorte.

Os mesmos pares de teclado são perfeitos com o iMac, por isso não é um problema de hardware. Pensamentos?

UPD : registros do bluetoothd & hcidump para vários tipos de tentativas, talvez isso possa ajudar

Answer 1

Tentei conectar esse teclado específico a vários laptos Dell XPS com o Ubuntu de 16.04 a 18.04 e nenhuma dessas tentativas funcionou usando todos os tipos de software: ferramenta CLI bluetoothctl , Ferramenta bluetooth do KDE, Gnome settings bluetooth GUI, alguma GUI de terceiros (nem me lembro do nome ATM).

Não teve a chance de experimentar hardware diferente, desistiu e comprou outro teclado.

Aparentemente, esse tipo de teclado não se conectará a um Dell XPS com o sistema operacional Ubuntu.
