Ubuntu 20.04 蓝牙无法正常工作

我已经安装了 Ubuntu 20.04，但蓝牙无法使用。但如果我从 USB 启动，蓝牙可以在实时会话中工作。有人能帮我吗？

答案1

我遇到了同样的问题，在从 Windows 热启动切换到 Ubuntu 后，蓝牙无法工作。我按照 Ubuntu 错误报告这里，并且蓝牙功能齐全。使用以下命令：

  1. sudo rmmod btusb
  2. sudo modprobe btusb

答案2

我在 Ubuntu 20.04 上遇到了同样的蓝牙问题，并通过这种方式修复

sudo apt install blueman

sudo add-apt-repository ppa:blaze/rtbth-dkms
sudo apt-get update
sudo apt-get install rtbth-dkms

sudo vim /etc/modules

注释掉所有并添加此行

rtbth

重启并打开

sudo blueman-manager

如果仍然不起作用，请尝试此操作

sudo rmmod btusb
sleep 1
sudo modprobe btusb

如果仍然不起作用，请尝试此操作

/etc/default/grub用此值更新

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nommconf pcie_aspm=off"

更新 grub

sudo update-grub

然后reboot享受你的音乐。

蓝牙 v5 更新

蓝牙v5固件解决方案源

如果您从命令获取信息：sudo dmesg | grep Bluetooth

... firmware file rtl_bt/rtl8761b_fw.bin not found

尝试下载固件并安装

wget https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_config
wget https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_fw

sudo mv rtl8761b_config /usr/lib/firmware/rtl_bt/rtl8761b_config.bin
sudo mv rtl8761b_fw /usr/lib/firmware/rtl_bt/rtl8761b_fw.bin
sudo ln -s /usr/lib/firmware/rtl_bt/rtl8761b_fw.bin /usr/lib/firmware/rtl_bt/rtl8761bu_fw.bin

我也遇到了这个问题。对我来说，错误与 python 有关。问题出在 3.7 版本上。对我来说，以下方法有效：

我卸载了蓝牙：

sudo apt remove blueman

sudo apt autoremove

然后将你的 Python 版本更改为 3.6 或 3.8：

sudo update-alternatives --config python3

如果此命令不起作用，您将需要运行：

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 2

然后重新运行命令，更改python版本。

要安装蓝牙，需要有 python-gi，为此，请执行以下命令：

sudo apt install python3-gi

之后，再次安装蓝牙：

sudo apt install blueman -y && blueman-manager

这些是我遵循的步骤，并且成功了，但也许只需更改 python 版本即可。当我尝试返回到 python 3.7 时，蓝牙再次停止工作。我不知道如何解决这个问题，我只是停止使用 3.7 版本。

希望这可以帮助。

答案4

我在配对 XBOX ONE 控制器时遇到了麻烦（在 19.10 中没有任何问题）。解决方案是禁用蓝牙 ERTM（https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1750146）

sudo su
echo 1 > /sys/module/bluetooth/parameters/disable_ertm
