ASUS X550LC 上的问题（安装 ubuntu 后）

我已经安装了Ubuntu 14.04在我的华硕 X550LC。这里我发现了一些问题：

  1. 蓝牙无法工作。
  2. 每次重启后亮度都会变为 100%。
  3. 亮度和网络控制快捷键不起作用。
  4. 网络 LED（连接到互联网时应为绿色）不工作。

为了解决亮度问题，我尝试了第一和第二种解决方案这问题，但这不起作用。

为了解决蓝牙问题，我尝试了软件中心的 Blueman，但没有作用。

对于亮度问题，请执行以下操作。

sudo gedit /etc/default/grub

找到包含“GRUB_CMDLINE_LINUX_DEFAULT”的行并将其更改为以下内容

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

保存并关闭 gedit，然后在终端中输入以下命令

sudo update-grub
