HP X360 SpectreにLinux Debian 11.5をインストールしました。 Bluetoothを確認すると常にグレーになり、次のメッセージが表示されますNo Bluetooth found. plug in a dongle to use Bluetooth"。
端末でこれを行うと：
sudo lsmod | grep blue
私は何も得られません（空の出力）。しかし、インターネット上で見つけたコマンド（bootctl、bluetoothctl、lspciなど）を使用して、次のような結果を得ました。
sudo lsmod | grep blue
#Output:
bluetooth 753664 11 btrtl,btintel,btbcm,bnep,btusb
ecdh_generic 16384 1 bluetooth
libaes 16384 2 bluetooth,aesni_intel
rfkill 32768 9 hp_wmi,bluetooth,cfg80211
crc16 16384 2 bluetooth,ext4
それでは、私のBluetoothドライバは何ですか？どのようにインストールしますか？
Windows 10、11ではBluetoothは問題なく動作しますが、Ubuntu、Debian、FedoraなどのLinuxシステムでも同じ問題が発生します。
