当我双启动时,我的华硕电脑似乎失去了蓝牙固件? 我已经重置了很多次……令人沮丧

我重置了很多次……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 

这就是我每次都要做的事情让蓝牙再次工作。

这是我唯一一次听说Ubuntu安装到硬盘驱动器时发生这种情况,但是我们可以在安装/lib/firmware/brcm后更改/lib/firmware/brcm上的属性,看它是否阻止文件被删除

 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

在进行分配升级之前,请记得sudo chattr -i /lib/firmware/brcm

当… / brcm文件夹设置为immutable时对linux-firmware的任何更新都将导致更新失败。 这将导致升级崩溃。

我在这里讲一个相当不幸的经历。
