[SOLVED] Bluetooth does not work

cribari · 2017-12-27 13:48:57

I installed Arch + KDE Plasma on a laptop that has an Intel 8260 wifi+bluetooth card.

Network:   Card-1: Intel Wireless 8260 driver: iwlwifi
           Card-2: Realtek RTL8111/8168/8411 PCIE Gigabit Ethernet Controller driver: r8169

Wifi works, but bluetooth does not work. bluez and bluedevil are installed and the bluetooth service has been enabled:

● bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
   Active: inactive (dead)
     Docs: man:bluetoothd(8)

rfkill list returns

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

I am running the stock Arch kernel (4.14.8-1-ARCH). I booted using the zen kernel but it did not help. Prior to installing Arch on this Laptop I ran Manjaro KDE on it and bluetooth worked flawlessly.

Suggestions are welcome. Thank you in advance.

EDIT: SOLVED by two cold boots.

sudo modprobe btusb
sudo systemctl restart bluetooth

systemctl status bluetooth returns

Hi. I have the very same problem here (from a XPS13 "16), with the very same symptoms, and about the same results from the command you typed. Loading btusb helped with the bluetooth service, but still no bluetooth adapter found.

I can agree sometimes reboot do work, but sometimes a dozen of reboot is not enough to make it work. I do not really know what to do here to solve this without rebooting.

About the same results do not have to be the same results. And whatever difference there might be might well be important. Either way this thread is [SOLVED] you should open your own with outputs and details from your own system instead.
