我的华硕电脑在双启动时似乎丢失了蓝牙固件？我已经重置了很多次了……真令人沮丧

我已经重置过很多次了...真令人沮丧。

wget https://www.dropbox.com/s/xbmm9vfg2fby2zn/fw-04ca_2006.hcd
sudo cp fw-04ca_2006.hcd /lib/firmware/brcm/BCM43142A0-04ca-2006.hcd
sudo modprobe -r btusb
sudo modprobe btusb

这是我每次让蓝牙重新工作所做的事情。

答案1

这是我唯一一次听说 Ubuntu 安装到硬盘时发生这种情况，但我们可以在/lib/firmware/brcm安装固件后更改属性，看看它是否能阻止文件被删除

wget https://www.dropbox.com/s/xbmm9vfg2fby2zn/fw-04ca_2006.hcd
sudo cp fw-04ca_2006.hcd /lib/firmware/brcm/BCM43142A0-04ca-2006.hcd
sudo chattr +i /lib/firmware/brcm/

重新启动并查看问题是否仍然存在

答案2

sudo chattr -i /lib/firmware/brcm 在进行分发升级之前请记住这一点 ！

当 .../brcm 文件夹设置为不可变时，对 linux-firmware 的任何更新都会导致更新失败。这反过来会导致升级崩溃。

我在这里讲一下一次相当不幸的经历。
