Vrushank V's questions

蓝牙驱动程序似乎存在问题，无法检测/连接到任何周围的蓝牙设备。我在另一个分区上有 Windows，我可以在那里访问蓝牙。
从下面的输出日志中可以看出 - 似乎有问题 - ：[13696.202909] bluetooth hci0: Direct firmware load for brcm/BCM43142A0-105b-e065.hcd failed with error -2 [13696.202917] Bluetooth: hci0: BCM: Patch brcm/BCM43142A0-105b-e065.hcd not found
我尝试了一些其他解决方案 - Ubuntu 20.04 蓝牙无法正常工作，并且还卸载、重新安装、升级 blueman 但没有运气。

如果有人帮助我解决这个问题，那将非常有帮助。如果需要，我很乐意粘贴更多日志:)
提前致谢。

因此，我搜索了一个解决先前存在的问题的方法，该问题需要我在启动过程中长按 SHIFT 按钮。它把 grub 菜单变成了这样。
现在我的 Grub 菜单的图像

在一切发生之前，它看起来有点像这样
（除了有 Windows 10 而不是 Windows 7）

这就是我的 Grub 文件的外观（单击）

GRUB_DEFAULT=0
.#GRUB_HIDDEN_TIMEOUT=0
.#GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR= lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
.#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
GRUB_TERMINAL=console
GRUB_GFXMODE=640X480
.#GRUB_DISABLE_LINUX_UUID =true
.#GRUB_DISABLE_RECOVERY="true"
.#GRUB_INIT_TUNE="480 440 1"

它在启动前给出错误提示错误：没有像这样激活视频模式 虽然它可以正常工作..这很烦人..我如何修复错误并恢复紫色 Grub 菜单？：/ 提前致谢 ：）

编辑： 感谢 Pratap，这两个问题现在都解决了。

嗨，关于我正在处理的错误。同时你可以在 GRUB_TERMINAL=console 和 GRUB_GFXMODE=640X480 之前添加#。添加 # 符号后，保存文件并关闭。更新后打开终端和 sudo update-grub。关闭终端并重新启动系统以查看更改。
