小米笔记本 Air 13.3 是一款铝合金的超级本，由小米公司生产，目前只能在中国购买，或者通过在线进口网站购买。第一代小米 Air 使用 Intel Core i5 6200U @ 2.3 Ghz a和 NVIDIA GeForce 940MX。小米笔记本以较低的价格提供了不错的性能。

如果你照着下面的步骤来安装，应该不会有任何问题

## 安装前准备

想要从Arch安装媒介引导启动十分简单。首先插入U盘，然后按开机键，并在开机过程中按F2，会进入UEFI设置：

- 安全 -> 设置密码
- 安全-> 关闭 Secure Boot
- 点击设置密码，但是把"新密码"一栏留空，可以实现重置密码

请参考 Installation guide (简体中文)获取更多安装帮助，安装过程应该不会有什么问题。

Note: 你的SSD硬盘叫 `nvme0n1`, 而不是 `sda`.

## 显卡设置

小米笔记本同时配有Intel的集成显卡和Nvidia的独立显卡。

### 只使用集显

如果你想完全禁用Nvidia GPU以提高续航，可以操作如下：

- 安装 xf86-video-intel
- 屏蔽内核模块 nvidia 和 xf86-video-nouveau ，参见 Kernel modules#Blacklisting

    /etc/modprobe.d/nouveau.conf

    blacklist nouveau
    blacklist nvidia

- 安装 bbswitch ，参见 turn off the card

    /etc/modprobe.d/bbswitch

    options bbswitch load_state=0 unload_state=0

### Intel/Nvidia 混合配置

You can enable hybrid GPUs by either using Bumblebee or NVIDIA Optimus. Bumblebee is generally better for battery-life and compatibility but not officially supported by NVIDIA.

Refer to the respective articles.

## 输入

### 触摸板

想要正常使用触摸板，你需要安装 xf86-input-libinput。如果你使用 xf86-input-evdev，你的触摸板会像触摸屏那样工作（e.g. 你在触摸板上的任何操作都直接映射到屏幕上）。如果你使用 xf86-input-synaptics (强烈不建议，因为它已经弃用了，参见 Synaptics) ，触摸板很可能只能偶尔正常工作。 libinput 配置文件结合 如下XOrg配置，可以使用双指手续，轻触点击，双指，三指点击等（双指点击等价与按住鼠标右键，三指点击等价于按住鼠标中键）。

    /etc/X11/xorg.conf.d/20-touchpad.conf

    Section "InputClass"
            Identifier "libinput touchpad"
            Driver "libinput"
            MatchIsTouchpad "on"
            MatchDevicePath "/dev/input/event*"
            Option "Tapping" "on"
            Option "ClickMethod" "clickfinger"
            Option "NaturalScrolling" "true"
    EndSection

### Fn功能键

默认Fn键是使能的，比如 按 F1 可以静音。 如果按这些Fn功能键没有反应，那么很可能你使用的是窗口管理器 Window manager (简体中文) 而不是桌面环境 Desktop environment (简体中文)。这时你需要添加相应的配置，比如利用Xbindkeys 或 i3的 `bindsym`。

大多数Fn功能键返回特定的键码，下面是一张表格：

Fn-F-Key | Keycode
--- | ---
`F1` | `XF86AudioMute`
`F2` | `XF86AudioLowerVolume`
`F3` | `XF86AudioRaiseVolume`
`F4` | `XF86MonBrightnessDown`
`F5` | `XF86MonBrightnessUp`
`F6` | `Super_L + P`
`F7` | `无`
`F8` | `Super_L + Tab`
`F9` | `无`
`F10` | `Turns Keyboard backlight on/off`
`F11` | `Print`
`F12` | `Insert`

## 显示校准

Factory display calibration is poor. In lieu of a colorimeter, try the ICC profiles at tlvince/xiaomi-mi-notebook-air-13.

## 排难解惑

### 背光灯

使用xorg-xbacklight和默认配置，你无法控制背光灯，因为背光灯路径不符合标准。想要解决这个问题，你需新建一个X-Org配置文件：

    /etc/X11/xorg.conf.d/10-backlight.conf

    Section "Device"
            Identifier "Card0"
            Driver     "intel"
            Option     "Backlight"  "intel_backlight"
            BusID      "PCI:0:2:0"
    EndSection

### WiFi

如果你无法自动检测WIFI驱动，可能是因为两个驱动冲突了，你可以使用 `rfkill list`解决它。屏蔽掉其中一个有问题的驱动可以这么设置：

    /etc/modprobe.d/blacklist.conf

    blacklist acer-wmi

注意，这个问题Linux 4.9以上的版本中已经解决了。
