Bluetooth Mouse randomly disconnects

I’m sorry because the only stable Real-time kernel is 5.4, and as you said anything prior to 5.5 is bad, I’m all out of ideas!

Sorry!

:sob:

I’m also having a similar problem lately with my bluetooth headphones. They seem to disconnect randomly while watching a video or listening to music, and it is really annoying.

I’m on kernel 5.9 btw.

That one is EOL, so upgrade to 5.10 LTS (Long Time support) or 5.4 LTS if the 5.10 doesn’t solve your issue…

:crossed_fingers:

I’m also experiencing bluetooth speaker randomly disconnecting but automatically reconnects.

OP never came back whether 5.4 LTS or 5.10 LTS solved the issue for him/her/other.

So did you try that out yet?

:thinking:

Up this, have the same problem with bluetooth headphones no matter the kernel (tried 5.9,10,11)

When trying kernels, look here first:

https://kernel.org

so try 5.4 LTS as that has been an LTS kernel for far longer than 5.10.

(and then feed back, please?)

i’m testing on 5.4 right now gonna let you know! Also noob question (i’m still pretty new to all this linux thing) going back to an older kernel won’t downgrage my drivers? Or they are bound to the majaro updates and not the kernel ones?

I was using 5.10 when this issue started happening. I think it started when the stable update that had the changes to the nvidia drivers came out. I’m not sure. I’m now on 5.11 and it’s still happening. Haven’t tried 5.4 though because I have some things that work better with 5.10 or above.

Another weird thing about this bug is when I’m playing a game and I have say spotify running, so there’s 2 different audio sources, and I have them both going to my earphones. In the background I have the bluetooth speaker connected but again I have both audio sources going to my earphones, so no audio coming out of the bluetooth speaker. Suddenly, out of no where, the bluetooth speaker disconnects, automatically connects, takes away the game audio, but for some reason the spotify audio is still going to my earphones. So the spotify audio is coming out of my earphones, the game audio is coming out of the bluetooth speaker. Even if I only have the bluetooth speaker running, it will randomly disconnect and reconnect.

so 3 hours in and it seems like everything is working as intended, installing 5.4 solved the problem

It’s not an older kernel it’s an LTS kernel.

Please read this:

especially the section “Linux has multiple kernels”

also read Alessio’s post above cc @wildcard

FYI there is a bug right now with AX200/AX201 chipset bluetooth modules. See https://www.reddit.com/r/linuxhardware/comments/m21yhj/fyi_bluetooth_on_intel_ax200_currently_broken/ for more info. Downgrading linux-firmware seems to help, according to the arch forum

Thank you, very useful resource!

Hello,
for me the problem still is the same.
On Kernel 5.4 my machine won’t boot at all.
The other versions all give me the behaviour as written in the first post.
Have tried a different BT Mouse with the same result.
All the same hardware still works fine under Win10, as this is a dual boot setup.

I can try a different Linux fron a live version in the next days.
But thanks for into it!

There are variants of this issue floating around in the internet, especially on the Arch forums. It looks like the blast radius is pretty large.

Here, it’s claimed that the root cause is a bug in bluez, which was patched 2 days ago.

Question to Manjaro devs: how can we get this patch in the quickest way? This is impacting a lot of us.

  • if it’s been patched in Arch, it’ll take 1-2 weeks before showing up in stable.
  • Having said the above, the devs don’t commit to timelines as they’ll release when it’s ready (I.E. out of testing)
  • If you want patches faster, subscribe to the testing branch (but that’s not stable so you could switch now and then switch back to stable once the issue gets releesed to stable)

:frowning:

I don’t think even testing has it yet. We need Bluez to officially release a new version, no?

I just got confirmation from ArchLinux folks that the patch in question made it into bluez 5.56-2. The current version in Manjaro is 5.56-1. Hopefully this will be fixed soon in the next update.

edit: 5.56-2 already in Manjaro unstable.

By the way, while we are waiting for the real fix, I noticed that downgrading linux-firmware makes the disconnects much less frequent for me.

pamac install downgrade

sudo DOWNGRADE_FROM_ALA=1 downgrade linux-firmware

I went with the last version from 2020, which seems to work fine.
