Function keys

F2 XF86AudioLowerVolume

F5 XF86MonBrightnessUp

To make F7 ("Scissors") work, one have to make sure "xiaomi_wmi" kernel module is loaded. This enables you to assign anything to the key.

Display

Factory display calibration is poor. Check the panel model:

$ edid-decode < /sys/class/drm/card0-eDP-1/edid | grep Alphanumeric

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

The path to the backlight is non-standard and causes tools like xorg-xbacklight to not work. 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"
