Dell XPS 13 (9370) 蓝牙问题

Dell XPS 13 (9370) 蓝牙问题

我的预装了 Ubuntu 的新款 Dell XPS 13 (9370) 上的蓝牙模块出现以下问题。

蓝牙模块因某种原因被禁用。蓝牙设备(键盘和鼠标)在工作过程中停止工作,蓝牙指示灯熄灭,模块也在列表中消失rfkill

为了让它恢复工作,我需要重新启动机器,启动 BIOS,禁用蓝牙模块并重新启用它。之后,蓝牙模块又可用了。这很烦人。

发生这种情况时我的系统日志:

我已经尝试了不同的事情:

  1. 禁用 TLP 并禁用蓝牙的 TLP/etc/default/tlp
  2. 将 BIOS 更新至版本 1.2.1
  3. 将此行设置为 ath10k 的 modprobe:echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
  4. 更新linux-firmware包,如下所述:https://www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debian

到目前为止,这些都没有任何帮助。

据我所知,它是以下硬件:QCA 6174 Killer 高通 / QCA 1535 Killer 高通

我主要将这两个蓝牙设备配对并连接:

  • 罗技 K810 键盘
  • 罗技 MX Anywhere2 鼠标

答案1

我遇到了同样的问题,我认为使用最新 Windows 驱动程序中包含的文件更新蓝牙固件可以改善这个问题。我的 MD5:

sonic@sonic-XPS-13-9370:/lib/firmware/qca$ md5sum *usb*302*
067fb95e8501bad2683df07d23539e7d  nvm_usb_00000302.bin

86c377ab7b2c24cc12cea5e79f71d610  rampatch_usb_00000302.bin_orig

顺便说一句,更简单的解决方法是拔掉电源并执行挂起/恢复循环。
至少我的是 1435 Killer。

答案3

找到了很多解决方案。只有一个有效!我使用的命令是

modprobe btusb && systemctl start bluetooth

您可能需要 root 权限。

我发现本论坛

您可能已经知道,蓝牙会在睡眠时关闭/消失。为此,可以添加一个脚本,在睡眠前关闭蓝牙,在睡眠后重新打开。

我将直接粘贴答案

只需将任意名称的可执行脚本放入 /lib/systemd/system-sleep/ 中。

#!/bin/sh
if [ "$1" = "pre" ]; then
  systemctl stop bluetooth && rmmod btusb
elif [ "$1" = "post" ]; then
  modprobe btusb && systemctl start bluetooth
fi

希望它也适合你!

另外,仅供参考,这是我的系统信息。

答案4

另一个线程有报告称更新到较新的内核(4.17 或更高版本)也可以解决该问题。

要在 Ubuntu 18.04 上执行此操作,请运行命令:sudo apt install linux-generic-hwe-18.04,然后重新启动。

我刚刚这样做了;所以,如果没有效果,我会报告。

我还可以确认,作为一种解决方法,暂停 ( Fn+ End[
