Eu tenho um Acer v5-471 executando o Xubuntu 17.10 e como eu disse no título não há bluetooth, o ícone do bluetooth não aparece, e o gerenciador do bluetooth diz "nenhum adaptador bluetooth encontrado", como pode eu corrijo isso?
aqui está a saída para lspci -nnk | grep -iA3 net; lsusb; dmesg | egrep -i 'blue|firm'
