Additional observation: Airplane Mode is also affected. When I enable Airplane Mode from GNOME Quick Settings, Wi-Fi is turned off correctly, but Bluetooth turns itself back on automatically. As a result, the Airplane Mode toggle also switches itself back off.
** Description changed: On Ubuntu 26.04 LTS, Bluetooth cannot remain turned off. When I turn Bluetooth off using either GNOME Quick Settings or Settings, it turns off briefly but then automatically turns itself back on. The Bluetooth controller confirms this behavior: immediately after turning it off, bluetoothctl show reports: Powered: no PowerState: off After a short time, without any user action, it changes back to: Powered: yes PowerState: on The Bluetooth adapter is a MediaTek device, USB ID 0e8d:e025, on a Lenovo ThinkPad P16s Gen 4 AMD. The kernel log also showed errors during the Bluetooth power-off sequence, including: Bluetooth: hci0: command 0x2039 tx timeout Bluetooth: hci0: failed to reset (-19) Bluetooth: hci0: Error when powering off device on rfkill (-110) Expected behavior: When Bluetooth is turned off in GNOME Quick Settings or Settings, it should remain off until the user turns it on again. Actual behavior: Bluetooth turns itself back on automatically after being turned off. This occurs consistently after a fresh installation of Ubuntu 26.04 LTS.
