"Unlikely error" with bluetooth

Help

1

On my Fedora 44 KDE Plasma laptop, bluetooth sometimes chokes and I have to restart it with `systemctl restart bluetooth`. Right now it did it again – I have two bluetooth mice and both suddenly refused to work, right in the middle of something. Like, I’m using the mouse and it suddenly stops responding. Then I take my other mouse and it won’t move the pointer either.

I found this in `journalctl -eu bluetooth`:

Web search makes me think that this error is non-specific, but maybe someone has a clue what might be going on. I don’t. Thanks.

Indeed nothing KDE or Plasma related.

That’s at the bluetooth level bluetoothd. Your mouse must have some quirks with its bluetooth implementation that isn’t well supported (or that’s an hardware bug), or the fact you have bluetooth two mice connected at the same time might trigger some issue.
You should start by specifying the model of mouse used.

Thanks. The main mouse is a Logitech M720 Triathlon, the other one is a Jelly Comb wireless trackball. Today I tried what happened with the trackball turned off, but with the Logitech mouse I still had these connection problems occasionally.

I should note that this also happens at home sometimes, where I use the same laptop, but a different mouse, a Logitech MX Anywhere 3S.

So maybe something related to my Thinkpad P14s’ bluetooth controller in conjunction with Linux drivers, who knows.

Probably I just have to live with it.

It might just be the two interfering with each other also.

Try to see if they are any reported issues with those with Bluetooth.

Try disabling power saving for the bluetooth controller first, then the devices if that doesn’t work on its own.
