Ubuntu 16.04.1 com kernel 4.12.10-041210-genérico intel 8260 bluetooth não funciona

Question

Estou em uma latitude Dell E7270 com o BIOS mais recente (setembro de 2017), executando o ubuntu 16.04.1. Eu primeiro atualizei o kernel 16.04.1 de estoque para a linha principal 4.11.7-041107-genérico sem problema, então atualizei para o kernel 4.12.10-041210-generic e o Wifi e o Bluetooth pararam de funcionar. Então eu instalei os firmwares mais recentes usando (não sei exatamente o que estava lá antes da atualização).

sudo dpkg -i linux-firmware_1.167_all.deb

Após a reinicialização, o Wifi começou a funcionar novamente, mas o Bluetooth ainda está inativo:

Portanto, parece que o intel / ibt-11-5.sfi é o culpado, mas não consigo encontrar nenhum firmware mais recente do intel bluetooth.

Alguma ideia?

EDITAR:

Após uma inicialização limpa, executar isso em um terminal corrige o bluetooth:

sudo modprobe -r btusb
sudo modprobe btusb

isso é adicionado ao dmesg:

No entanto, eu preciso modprobe manualmente após cada reinicialização. Alguma idéia de como consertar isso para que funcione logo após o boot?

    

Answer 1

Adicione btusb a /etc/modules ...

gksudo gedit /etc/modules

isso fará com que btusb seja carregado no momento da inicialização.
