Ákos Maróy (akos-maroy) wrote : Bluetooth not working on Dell XPS 15

Bluetooth doesn't work on the Dell XPS 15 laptop, with Ubuntu 18.04.

expected behavior:

in Settings, one goes to the Bluetooth tab, slides the 'ON' button to 'ON', and then Bluetooth is enabled, and one can pair devices

what is happening:

in Settings, when clicking on the 'ON' button in the Bluetooth tab, it seems to turn on, that falls back to off

some relevant output:

$ uname -a; lspci -nnk | grep -iA2 net; lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; lsmod | grep bluetoothLinux
