Dell XPS 13（9370）Bluetoothの問題

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：

  1. /etc/default/tlpでBluetoothのTLPを無効にし、TLPを無効にします
  2. BIOSをバージョン1.2.1に更新する
  3. この行をath10kのmodprobeに設定：echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
  4. ここで述べたようなlinux-firmware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。

  • Logitech K810キーボード
  • Logitech MX Anywhere2マウス

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：

sonic@sonic-XPS-13-9370:/lib/firmware/qca$ md5sum *usb*302*
067fb95e8501bad2683df07d23539e7d  nvm_usb_00000302.bin
b3e2784b16b5b0cf5defa7eb9115956d  nvm_usb_00000302.bin_orig
c9d6334b547a92817458de10243f398c  rampatch_usb_00000302.bin
86c377ab7b2c24cc12cea5e79f71d610  rampatch_usb_00000302.bin_orig

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。
