[MULTI BOOT] No Bluetooth on the Linux side

[Clayman1000x]

I just bought a new laptop, an Asus Tuff F17, FX706HE-211.TM17-1. Some of the changes I made were updating Win10 home to Pro and adding Kubuntu 20.04 dualboot. Everything works fine but the bluetooth in Kubuntu. No adapter even exists yet I know there is one because I can use it in Windows, so I know the hardware is there. Asus has been no help and google has been very little, I can't even figure out what hardware this is.

According to device manager in windows the bluetooth hardware is a "media tek bluetooth adapter"

We'll need to see some info about the adapter.

Bluetooth is usually listed as a USB device, so this command will list them:
lsusb
Paste the output into a reply. It will look something like this:

$ lsusb

Also, the lspci command will list other devices, such as wifi cards. Bluetooth is usually a component on these cards, so any lines related to wifi might help get the specific card you have nailed down, and we can see what options are available.

I may not be running the correct kernel for the mediatek hardware. I had to upgrade to kernel 5.13 to get the wifi to work and from what I found I need at least kernel 5.15.6.to get bluetooth working. I tried installing that kernel 5.15 but got errors. 22.04 comes out next month so I might have to wait for that upgrade.

And the lspci info?

You likely need to install a new kernel for this fairly new chipset. If it is the model I suspect, wifi didn't work until kernel 5.12, and 20.04 now has 5.13, but you likely need a 5.15 or newer kernel from Mainline, or to test, you might try booting a 22.04 pre-release iso and see if it works there.
Even then, it may still be problematic and need tweaks and fixes, so be prepared for that.

A few folks gave up and installed a much better supported card but these were older posts.
It is what I did for my PC with perfectly fine realtek Wifi (that I do not use) but completely unreliable bluetooth (which I do use heavily), even via manually compiled drivers etc ad nauseum.

I think you are right claydoh, I've been reading on some things I managed to find saying the same about the kernel. So it looks like 22.04 LTS will be out next month and I have a usb bluetooth to use until this gets sorted out. Thanks for your help though.

[claydoh]

Check out a live session of 22.04 and see if it is working there.
Else try different 5.15, or 5.16 Mainline kernels, and even 5,17s are available iirc.

If Mainline kernels are still not working on 20.04 ( I forget that this may still be the case), you *might* consider trying out xanmod or other third party kernel build repos, the Mainline kernels are often too vanilla, missing or not including some patches for everything
