公開済みBugzillaの@ArtemS.Tashkinovが提案したように
私のHPノートブックでLinuxを実行すると、Bluetoothアダプタはスリープ後に消え（常に）、再起動後に再び表示されるため（常に）起動時にBluetoothを使用してすべての操作を実行するのが解決策かもしれません。これはUbuntuとFedoraの両方で発生しますが、Windowsでは発生しません。私は現在Fedoraを使用しているので、ソリューションがディストリビューションに特化している場合は、そのディストリビューションに適している必要があります。更新、使用、再起動しようとし
ましたが、何も機能しません。bluezmodprobebluetooth.service
