Eu tenho um Dell Inspiron rodando o Ubuntu budgie 17.10 e depois de instalar algumas atualizações não há bluetooth, o ícone bluetooth não aparece, e o gerenciador bluetooth diz "nenhum adaptador bluetooth encontrado", como posso corrigir isso?
aqui está a saída para lspci -nnk | grep -iA3 net; lsusb; dmesg | egrep -i 'blue|firm'
