Bluetooth no funciona en ubuntu 18.04 (Dell inspirion 11 3148)

Recientemente hice un arranque dual con Windows 10 y Ubuntu 18.04, pero tengo problemas porque Bluetooth no descubre dispositivos. Simplemente sigue buscando dispositivos. Sin embargo, el Bluetooth es visible en otros dispositivos.

Intenté prácticamente todo lo que encontré. Probé estos:

  1. Ubuntu 18.04 LTS bluetooth [0cf3:3004] el descubrimiento no funciona
  2. https://www.devmanuals.net/install/ubuntu/ubuntu-16-04-LTS-Xenial-Xerus/how-to-install-bluetooth.html

Correr:

lspci -nnk | grep -iA3 net; lsusb; rfkill list; uname -r; dmesg | egrep -i 'blue|firm'

La ventana de Bluetooth está fija como se muestra en esta captura de pantalla y nunca cambia:

Soy nuevo en Linux, así que intente explicar un poco los comandos que pueda sugerir.
