Estou usando um Thinkpad X1C (5 gen), executando o Ubuntu 16.04 com o kernel 4.13.0.
Meu bluetooth funciona bem até que eu retome do sono, ele diz que o bluetooth está desativado. Eu tentei vários métodos para reativá-lo, mas todos falharam, exceto a reinicialização.
a saída de lsusb; lsmod | grep bluetooth; dmesg | O firmware do grep é:
