The Mi Notebook Air 15.6 is an aluminium notebook. It is a product by the Chinese Company Xiaomi.

The installation should be going without any problems if you follow the following steps.

Pre-Installation System Settings

It is actually very easy getting the Arch Installation Medium to boot properly. Prior to booting the Arch installation ISO enter the UEFI menu by pressing F2 during Boot.

  • Security -> set password
  • Security -> Disable Secure Boot
  • reset the password by setting the password again but letting the "New Password" fields blank

Installation of Arch can proceed normally. Refer to the Installation guide for more info.

Note: Remember that your SSD is called nvme0n1, not sda.

Graphics Card Configuration

The Mi Book has an Intel, as well as an NVIDIA GPU.

Intel Only

If you want to completely disable the NVIDIA GPU (which might save batterlife), do the following:

/etc/modprobe.d/nouveau.conf
blacklist nouveau
blacklist nvidia
/etc/modprobe.d/bbswitch.conf
options bbswitch load_state=0 unload_state=0

Intel/NVIDIA Hybrid Configuration

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.

Note that included MX150 GPU does not properly work with VDPAU. It also does not work with NVDECODE and NVENCODE. Thus, video playback works faster and better with Intel's chip with VAAPI on this particular notebook. Even though it supports specifications, this particular GPUs hardware acceleration APIs do not work with the proprietary NVIDIA driver (nouveau needs to be tested). The only benefit of NVIDIA GPU is better performance on high-resolution screens and CUDA/gaming.

While video playback performance is best with Intel VAAPI, battery life is best when relying on CPU for video decoding (as VDPAU/NCDECODE/NVENCODE does not work).

Input

Touchpad

To use the touchpad like a normal one, you have to use xf86-input-libinput. If you use xf86-input-evdev, your touchpad acts like a touchscreen (e.g it maps your movements directly to your screen). But if you are using xf86-input-synaptics (although you really should not, because it is deprecated (see Synaptics)) things are only working sporadically. This configuration of libinput using XOrg configuration files enables two-finger gestures, tap-to-click and 2-and 3-finger clicks (for right- and middle-click respectively).

/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-Keys

On this notebook, the Fn-keys are enabled as default (e.g. pressing F1 mutes the sound). If pressing the keys does nothing you are most likely using a Window manager and not a Desktop environment. Use the respective configuration files to bind the keys to their use. For example Xbindkeys or i3's bindsym.

Most Fn-keys return the correct keycodes. Here is a table containing that information:

Fn-F-Key Keycode
F1 XF86AudioMute
F2 XF86AudioLowerVolume
F3 XF86AudioRaiseVolume
F4 XF86MonBrightnessDown
F5 XF86MonBrightnessUp
F6 Super_L + P
F7 Nothing
F8 Super_L + Tab
F9 Nothing
F10 Turns Keyboard backlight on/off
F11 Print
F12 Insert

Display Calibration

Factory display calibration is poor. Check the panel model:

$ edid-decode < /sys/class/drm/card1-eDP-1/edid | grep ASCII

If it's NV156FHM-N61, try the ICC profiles at [1].

Troubleshoothing

Backlight

You can adjust brightness directly (works even with modesetting driver):

# echo 7500 > /sys/class/backlight/intel_backlight/brightness


However, if you use a tool like xorg-xbacklight in its default configuration, nothing happens, because the path to the backlighting variable is not standard. To fix this issue, you have to setup Intel driver and add Backlight option to respective X-Org configuration file:

/etc/X11/xorg.conf.d/10-backlight.conf
Section "Device" 
        Identifier "Card0" 
        Driver     "intel" 
        Option     "Backlight"  "intel_backlight" 
        BusID      "PCI:0:2:0"
