Xiaomi Air 13: minimal Ubuntu installation and power optimization steps

Preparation

Make bootable flash drive. Personally I don't use flash drives and I have only one with some files on it. I used this wiki https://wiki.archlinux.org/index.php/Multiboot_USB_drive to prepare multi boot usb.
Download your favorite ubuntu distro. Without reason i chose xubuntu 16.04 (LTS).

after testing it turned out that unity DE with default settings is less efficient than XFCE : minimal power consumption 7W vs 4W.

Power off laptop, power on and press F2 to get in BIOS(?). If I do reboot F2 doesn't work.
Select usb to boot from. If you created usb without UEFI choose legacy mode in boot menu. Save - Reboot
Boot to xubuntu-desktop and run gparted in terminal: sudo gparted. I created 4 partitions for root - / , for /home, swap 8Gb and EFI one (200Mb). Efi partition I did with idea to change boot linux or windows in bios only. Thus I can make grub transparent (without menu and s etc.) when laptop start from hibernate.
You may check power consumption with live usb, in terminal upower -d in my case with USB plugged it was about 7W
I downloaded lubuntu alternate to make minimal installation

Installation

You may want use wifi, in terminal: sudo modprobe -r acer_wmi; sudo service network-manager restart
Start Installation icon. Make some steps. Downloading updates and HD youtube music video will slow down installation.
At page with third-party software you must Turn off secure boot . Without this step we will not be able install efficient NVIDIA driver blob.
Answer no to unmount /dev/sda
In HDD partition selection I chose Something else to do manual selection.
Chose partitions for / and /home and uefi
Make obvious steps: your location, your language, your login details
reboot in ubuntu you probably will need select proper boot order in BIOS

Configuration

Unlock secure boot: follow instructions on blue screen.

sudo modprobe -r acer_wmi
sudo service network-manager restart
sudo -i
echo 'blacklist acer_wmi' >> /etc/modprobe.d/blacklist.conf
exit
