Public bug reported: I've run into this bug on Linux Mint 22.2 (based on Ubuntu 24.04) but also reproduced it with Ubuntu 25.04 live usb key running kernel 6.14.0. All the following information come from the live Ubuntu system.
Looks like on Lenovo Legion 5 series the bluetooth hardware is not recognized as it should. Specifically, mine has S/N PF5T84HL. From the discussion on Mint forum it seems to be a problem with the btusb kernel module. Symptoms: - going in the bluetooth settings window and trying to enable it doesn't do anything (the button remains in "off" state) - trying to turn on bluetooth on the terminal with bluetoothctl shows "No default controller available": ubuntu@ubuntu:~$ bluetoothctl [bluetooth]# Agent registered [bluetooth]# power on No default controller available [bluetooth]# scan on No default controller available [bluetooth]# exit The laptop details page on Lenovo website reports that the wireless connectivity includes "Wi-Fi 7 2x2 BE 160 MHz e Bluetooth® 5.4". Lenovo support website reports that the latest BIOS update is from Sep 2025 (1 month ago at the time of writing) with version S2CN20WW, but it's only for Windows: https://pcsupport.lenovo.com/fr/en/products/laptops-and-netbooks/legion-series/legion-5-15iax10/83f0/83f0cto1ww/pf5t84hl?linkTrack=Homepage%3ABody_Search%20Products&searchType=6&keyWordSearch=PF5T84HL I'm currently running with S2CN15WW, which to my knowledge is the latest available on Linux. Here's my system information and other diagnostic output I could pull down: System information: # System Details Report --- ## Report details - **Date generated:** 2025-10-04 11:01:10 ## Hardware

All the following information come from the live Ubuntu system. Looks like on Lenovo Legion 5 series the bluetooth hardware is not recognized as it should. Specifically, mine has S/N PF5T84HL. From the discussion on Mint forum it seems to be a problem with the btusb kernel module. Symptoms: - going in the bluetooth settings window and trying to enable it doesn't do anything (the button remains in "off" state) - trying to turn on bluetooth on the terminal with bluetoothctl shows "No default controller available": ubuntu@ubuntu:~$ bluetoothctl [bluetooth]# Agent registered [bluetooth]# power on No default controller available [bluetooth]# scan on No default controller available [bluetooth]# exit The laptop details page on Lenovo website reports that the wireless connectivity includes "Wi-Fi 7 2x2 BE 160 MHz e Bluetooth® 5.4". Lenovo support website reports that the latest BIOS update is from Sep 2025 (1 month ago at the time of writing) with version S2CN20WW, but it's only for Windows: https://pcsupport.lenovo.com/fr/en/products/laptops-and-netbooks/legion-series/legion-5-15iax10/83f0/83f0cto1ww/pf5t84hl?linkTrack=Homepage%3ABody_Search%20Products&searchType=6&keyWordSearch=PF5T84HL I'm currently running with S2CN15WW, which to my knowledge is the latest available on Linux. Here's my system information and other diagnostic output I could pull down: System information: # System Details Report --- ## Report details - **Date generated:** 2025-10-04 11:01:10 ## Hardware
