The bluetooth on my system isnt working

Pratham-saraf · 2022-09-17 18:27:27

I have tried to reinstall the arch multiple times yet to no avail.
bluetoothclt always results in

 
No default controller available

lsmod | grep btusb

outputs nothing so i modprobed it. The outputs are

btusb                  69632  0
btrtl                  28672  1 btusb
btbcm                  24576  1 btusb
btintel                49152  1 btusb
btmtk                  16384  1 btusb
bluetooth             937984  12 btrtl,btmtk,btintel,btbcm,bnep,btusb

the status of bluetooth service is

Welcome to the forums. It does not not appear that you have any Bluetooth hardware.
Is this a virtual machine?
Please post the unfiltered output of lspci

no this is not a virtual machine

Unless the Realtek RTL8723DE does Bluetooth, I don't see anything else that might on the PCI bus. There was nothing on the USB bus either.
Are you sure that system is supposed to have Bluetooth?

Pratham-saraf · 2022-09-17 18:51:58

i have dual booted my system , the bluetooth works on the windows side but it doesnt on the arch side.

ewaller · 2022-09-17 19:01:53

Windows.

I bet fast boot is turned on in Windows, and Windows is antisocial. You need to disable fastboot

https://www.windowscentral.com/how-disa … st-startup
https://help.uaudio.com/hc/en-us/articl … ailable%22.
https://www.makeuseof.com/windows-11-tu … t-startup/

And, it is a zombie. It will reanimate itself -- you have to keep turning it off, pretty much anytime Windows updates, or when Microsoft gets a whim. The only way to be sure is to nuke it from orbit (uninstall Windows and use the space foe something useful like cat videos)

... but i digress.

Turn of Windows fast boot and make sure Windows really, really shuts down rather than just pretending to. Then boot Linux and try Bluetooth again.

ugjka · 2022-09-17 19:53:47

Is this a laptop? Not only you need to disable fast boot but sometimes you need to take out the battery to completely reset the chips.

My shitty laptop has this problem

Pratham-saraf · 2022-09-17 19:58:39

The fast boot is already disabled on my system

The battery isnt a click slide one so to remove it i would have to open up entire back panel of my laptop

ugjka · 2022-09-17 20:09:12

That would be last resort measure in that case, try everything else first

ugjka, you need to treat yourself to a better system.

Pratham-saraf, Did you check it? Microsoft is being particularly antisocial with this 'feature' and they really do turn it back on randomly no mater how many times you turn it off.

Pratham-saraf · 2022-09-17 22:04:50

i open windows like once in 6-7 months that too if i am particularly reinstalling the system,
and the fast boot is already disabled also i shift shutdowned the system

ewaller · 2022-09-17 23:37:00

Well, all I can suggest is to boot into Windows and find out what type of device it is and which bus it is on. If it does not show up under Linux on either the USB or PCI busses, there is not much you can do.

Maybe the manufacturer of your system does not like Linux and is hiding things. You may have to pass an kernel command line parameter from your boot loader to tell the kernel to lie about what it is to the system firmware. https://www.kernel.org/doc/html/v4.14/a … eters.html ; see 'acpi_os_name'

how do i find the device bus like i know its Realtek RTL8723DE bluetooth device but how do i know its bus and how would that be useful

lspci shows what is on the PCI bus, lsusb shows what is on the USB bus(es).

Arch Linux
