Ubuntuがプリインストールされている新しいDell XPS 13(9370)のBluetoothモジュールには、次の問題があります。
何らかの理由でbluetoothモジュールが無効になります。 Bluetoothデバイス(キーボードとマウス)は作業の途中で動作を停止し、Bluetoothインジケータが消え、モジュールもrfkill
リストに表示されなくなります。
動作させるには、マシンを再起動し、BIOSを起動して、Bluetoothモジュールを無効にしてから再度有効にする必要があります。その後、Bluetoothモジュールが再び利用可能になります。それはかなり迷惑です。
これが発生したときの私のsyslog:

私はすでに別のことを試しました:

パッケージの更新: https://www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debianこれまで何も役に立たなかった。
私が見る限り、それは次のハードウェアです:QCA 6174 Killer Qualcomm/QCA 1535 Killer Qualcomm
ほとんどの場合、これら2つのBluetoothデバイスをペアリングして接続します。
同じ問題がありましたが、最新のWindowsドライバーに含まれているファイルを使用してBluetoothファームウェアを更新することで改善されたと思います。私のMD5:

ちなみに、簡単な回避策は、電源を抜いてサスペンド/レジュームサイクルを実行することでした。
そして、少なくとも私のものは1435キラーです。

別のスレッド には、新しいカーネル(4.17以降)への更新でも問題が解決するという報告があります。
Ubuntu 18.04でこれを行うには、コマンドSudo apt install linux-generic-hwe-18.04
を実行してから再起動します。
私はこれをやっただけです。そのため、うまくいかない場合は報告します。
回避策として一時停止することも確認できます(Fn+End[????])電源を抜いた状態でノートパソコンを覚醒させると、WiFiとBluetoothの両方の機能を再び有効にすることが一般的に信頼できます。
