Intel Compute Stick (STCK1A8LFC) + Xubuntu 18.04.4

To avoid agonistic wifi settings, better install Xubuntu Desktop first.
Thanks to wifi drivers delivered with bionic, wifi works on installation.

Hardware

Intel® Compute Stick STCK1A8LFC

Prerequisites

prepare installation media

at least 2GB USB memory stick as installation media
Xubuntu Desktop installation is preferred for better wifi device detection
download xubuntu-18.04.4-desktop-amd64.iso (1534459904 bytes) and burn it to USB memory stick

equipments

USB power supply (Type-A) and power cable (micro-B, packaged with STCK1A8LFC)
HDMI extension cable (packaged with STCK1A8LFC)
HDMI display
wifi station/home router connected to internet
USB HUB (Type-A) with at least 3 Type-A receptacles
- Keyboard
- Mouse
- Installation media (as described above)
at least 16GB microSD card as DUMMY system storage
- Ubiquity (Ubuntu installer) refuses to proceed if only internal MMC exists
- internal MMC is 8GB small, insufficient but still actually installable
- better use this external microSD than internal MMC anyway

update BIOS (could be done later)

visit Intel Site and search STCK1A8LFC
- https://downloadcenter.intel.com/ja/product/86613/-Compute-Stick-STCK1A8LFC

BIOS settings

press F2 during boot to enter BIOS setup
check SecureBoot and Performance settings
see Install Ubuntu Server 18.04.2 on Intel Compute Stick Guide

LAN

see wifi MACs (marked on Compute Stick surface)
permit wifi MACs on wifi station/home router per-SSID settings
write down available SSID and WPA2 PSK

installation

use English, do not change timezone nor keyboard mapping (set later)
- avoiding unnecessary heuristic locale settings depending timezone
do not connect to Internet during installation (connect later)
- some gigs of free space remained for /var/cache/apt

Post-install

Cstate-related problems

bay trail SoC has broken sleep state. it hangs randomly. fundamentally, cooling failure.

sudo vi /etc/default/grub modify GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

even after above, transition to sleep state seems still fatal. so,

sudo apt remove thermald

CUI/GUI

sudo systemctl set-default {multi-user,graphical}.target

inactivate unattended-upgrade

see and modify /etc/apt/apt.conf.d/20auto-upgrades as you like

wifi

edit /etc/netplan/01-network-manager-all.yaml and perform netplan generate netplan apply

# Let NetworkManager manage all devices on this system
network:
  version: 2
  wifis:
      wlan0:
          access-points:
              <ssid>:
                  password: <WPA2 PSK>
  renderer: NetworkManager

Japan-only settings (no Japanese packages required) as you like

timedatectl set-timezone Asia/Tokyo
localectl set-keymap jp

(optional) add your bread-and-butter packages

sudo apt install tree curl jq git apt-transport-https socat build-essential ssh xorgxrdp-hwe-18.04 xrdp
