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。
Bluetoothモジュールは何らかの理由で無効になります。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するだけで、Bluetoothインジケーターは消え、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。それはかなり面倒です。
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:
- BluetoothのTLPの無効化とTLPの無効化
/etc/default/tlp
- BIOSをバージョン1.2.1に更新する
- この行をath10kのmodprobeに設定します。
echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
linux-firmware
ここで述べたように、パッケージを更新します: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
