Bluetooth problem

Some help needed a few days ago i had my bluetooth headphones connected and they started running out of battery (normally i would turn them off) so i turned on the other pair of headphones and got distorted sound out of them, restarted the laptop ever since then i cannot connect to bluetooth devices. What i have tried check the kernel is not 5.8, make sure the service is on, reloaded old time shift images, tried to connect different devices, install blueman, nothing has worked so looking on the google

  • Kernel: 5.7.19-2-MANJARO is EOL so 5.4 LTS or 5.8 or 5.9-rc6 should be your first step.

  • Also after doing that, un-pair all devices and re-pair them.

  • just in case you now have multiple Bluetooth managers installed, what’s the output of:

    systemctl list-units --type=service --all | grep blue


bluetooth.service                                     loaded    active   running Bluetooth service  

I have unpaired all devices i cannot add any of them i tried 5.8 its the same, i’ll try 5.4 and 5.9

  • Only one Bluetooth Manager installed: Good!

  • Only one device can be active, so unpairing and deleting all devices should get rid of the one causing your issue.

What do you still see in your UI and which version of the kernel are you running on now?

I’m running KDE normally in the bottom bar theres a bluetooth icon which is missing one reason i installed blueman, in the KDE settings there is no bluetooth, running 5.7.19

I have posted a question regarding Bluetooth. Can someone please look in to it?

Get rid of 5.7 ASAHP. Have you tried 5.4 and 5.9RC3 already?

That is crucial information and should have been posted in your original question. Does that also happen if you create a new user and log in there?


woke up this morning read these posts before trying anything tried to pair the head phones with blueman, paired and sounded normal but still no bluetooth icon in the bottom KDE tray, so not sure what fixed the problem still running 5.7 and same user account

between the last un-pair everything and re-pairing did you reboot???

With kernel 5.7 I had bluetooth problems and had to switch to 5.4.

i unpaired everything rebooted and then tried pairing again and no devices could be found after that i posted on here and the facebook forum, when waking up this morning read the new replies on here before trying anything suggested tried to pair again and it worked

i tried 5.4 5 minutes ago it would not boot into manjaro just got a black screen so sticking with 5.7

As I see the Lenovo Legion 5 15ARH05 is brand-new, just a few months old. Then older kernels aren’t the solution.

yup i only have had luck running 5.6-5.8 for some reason does not even want to install 5.9 RC4 it says failed no error description in show more but i am fine with 5.7

I can only hope, a newer working kernel fix the problem for you. :sweat_smile:

yup newer kernels usually fix any problems , but for this i cannot say what the solution was
