Fedora 30を実行するThinkpad X1 Carbonの第7世代を使用しています。私の問題は、Bluetoothを操作できないことです。私はこの問題を解決するためにいくつかの方法を試しましたが、役に立ちませんでした。
- 設定GUI経由
設定/ブルートゥースに移動すると、Bluetoothの電源を入れることができます（右上にあるトグルスイッチ）。ところで文字は変わらず、Bluetoothがオフになっていると浮かびます。
iwlwifi.conf
もちろん、BIOSでBluetoothが有効になっていることも確認してみました。さらに、/etc/modprobe.d/iwlwifi.conf次のように生成します。
options iwlwifi bt_coex_active=0
- TLP
最後にこれを次のように設定しました/etc/default/tlp（関連抜粋のみ）。
[…]

- 人間とコンピュータの相互作用の構成
また、Bluetoothの電源最適化を無効にしようとしましたが、切り替えたいときに実行しようとpowertopしました。>> /usr/sbin/hciconfig hci0 up &> /dev/null &
>> Good Bluetooth device interface status
フェドラ実行時（？）がなく、bin手動で実行sbinしますsudo /usr/bin/hciconfig hci0 up &> /dev/null。
- CLI経由でBluetoothをオンにする
$ sudo hciconfig up

rfkill状態確認
ここではそれが問題ではないようです。
$ rfkill

- 調査を通過
dmesgを使用して手動イベントを追加しました# comments。コンピュータの電源を入れて左上のメニューに移動すると、Bluetoothを「オフ」にすることができます...ステータスは「オフ」です！

これらすべてはまだ効果がありません。
➥Bluetoothを実際に動作させるには？

まあ、ちょっと変な感じもするけど…Bluetoothデーモンはまったく動作しません！
だから私はこの問題を次のように解決しました。
systemctl enable bluetooth
望むより！
