Bluetooth Stopped working after update

General system Kernel & Hardware
1

Hey guys my Bluetooth stopped working after the latest update. It does show enabled when I do systemctl status bluetooth, but it doesn’t show in settings. Any help would be greatly appreciated.

Bluetooth and break a bit when kernels update. Try the lts kernel for now (or vice versa). It’s easiest to wait a few days.

it seems i’m currently enjoying a similar issue, details found in this post.

so far, no solution other than switching to lts has been found (which i’m hesitant to do) – will drop by in case we find something

Why would you be hesitant to run the lts?

i mean in this case, as a solution to the issue – i didn’t think that this would solve my specific issue; sorry to say i was right

Thanks, appreciate your help

but only to confirm… the underlaying issue must be hardware specific… i just tested with main kernel and 4 usb dongles… all working just fine.

If it’s kernel related, your other alternative would be to dive into the kernel and fix it and then push it upstream.

But more than likely if you’re not normally a kernel developer, the lts is usually your easiest fix for a point release or two.

Are you part of the kernel team at the Linux foundation?
