Public bug reported:
Information:
- OS: Kubuntu 26.04 LTS
- KDE Plasma Version: 6.6.4
- KDE Frameworks Version: 6.24.0
- Qt Version: 6.10.2
- Kernel Version: 7.0.0-15-generic (64-bit)
- Hardware: Dell Inc. Dell 16 Plus DB16250
- CPU: Intel Core Ultra 9 288V
- Wi-Fi/Bluetooth Chip: Intel Corporation BE201 320MHz [8086:a840] (rev 10)
Expected Behavior:
Bluetooth should be operational, and the Intel BE201 controller should be
detected by the system to allow connections to wireless devices.
Actual Behavior:
Since upgrading from Kubuntu 25.10 to 26.04, the Bluetooth adapter is
completely missing from the KDE system settings ("No Bluetooth adapters
found"), even though the bluetooth.service is active and running. This seems to
be a kernel/driver regression with the Intel BE201 chip on Kernel 7.0.
Steps to Reproduce:
1. Upgrade from Kubuntu 25.10 to 26.04 LTS on a Dell 16 Plus (Intel BE201).
2. Boot into Kubuntu (Kernel 7.0.0-15-generic).
3. Open KDE System Settings -> Bluetooth.
4. Note that no Bluetooth adapter is found.
