An annotation screen recording of the issue
Unable to connect paired wireless bluetooth headphones. Through the bluetooth
widget, and cli. The headphones show up in the widget just fine and connect for
a few seconds, before disconnecting.
STEPS TO REPRODUCE
1. From a fresh fedora 43 workstation, install the @kde-desktop-environment
metapackage,
2. Disable the gdm systemctl unit and enable the sddm unit,
3. Log into a KDE session, and attempt to connect to a bluetooth device through
the bluetooth widget in the system tray.,
OBSERVED RESULT
The headphones momentarily connect, before spontaneously disconnecting after a
few seconds. I am able to hear audio in the time before the device disconnects.
Running
> "journalctl -f"
gives these possibly related lines:
> Dec 23 17:18:14 fedora systemd[9645]: Reached target bluetooth.target -
> Bluetooth.

> Dec 23 17:18:19 fedora plasmashell[6630]: No object for name
> "bluez_output.41_AA_01_3B_F6_51.1"
EXPECTED RESULT
Headphones connect and pair normally. Without needing to restart the bluetooth
systemd unit.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Linux 43
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
ADDITIONAL INFORMATION
I few days ago I used fedora's dnf group policy to replace the GNOME desktop
environment with KDE plasma.
> dnf install @kde-desktop-environment
I have made sure that bluedevil is installed, and blueman is uninstalled. I
have tried forgetting and re-pairing the headphones. The only solution is to
run "systemctl restart bluetooth" and then attempt to connect them again. This
provides a temporary fix, but the problem re-occurs across reboots.
Additionally, I have also disabled the default GNOME display manager service,
replacing it with sddm
> sudo systemctl disable gdm
> sudo systemctl enable sddm
