# A roundabout way to get Ubuntu Artful alpha (17.10) on EDGAR (Acer Chromebook 14 4GB version - CB3-431-C5FM)

# Install missing 'legacy' BIOS piece to enable Ctrl-L on boot:
cd; curl -LOk https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh

# Install Galliumos (nightly - as of 09/09/2017)
# https://wiki.galliumos.org/Installing

cd; curl -LOk https://chrx.org/go && sh go -d galliumos -e desktop -r nightly -v 

# You need at least a standard/desktop edition or else you may end up with a blank console with Ubuntu minimal
# If you use Ubuntu 17.04 instead, keyboard and trackpad will be non-functional until kernel upgrade

# Optional: install apt-fast for concurrent downloads of packages
sudo add-apt-repository ppa:saiarcot895/myppa
sudo apt-get update
sudo apt-get install apt-fast

# Enable prerelease and testing to enable and obtain kernel 4.12.x install
sudo galliumos-repodist --enable prerelease
sudo galliumos-repodist --enable testing
sudo apt-get update
sudo apt-fast upgrade 

# Add artful to /etc/apt/sources.list
# It is cleaner to use /etc/apt/sources.list.d

# Ready to go to 17.10 
sudo apt-get update
sudo apt-fast dist-upgrade

# You could use 'sudo do-release-upgrade -d' instead of dist-upgrade

# !!Reboot - welcome to 17.10!!

# Optional post-install tweaks
# Upgrade Intel and Mesa drivers to oibaf's builds

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-fast update

# Enable Intel ilo gallium driver - if not using Wayland 
# Put in /etc/X11/xorg.conf:
Section "Device"
 Identifier "Device0"
 Driver "Intel"
 Option "DRI" "ilo"
EndSection

# Install Chrome stable

sudo apt-fast update
sudo apt-fast install google-chrome-stable

# Install Chrome Canary (unstable) and override GPU blacklist in chrome://flags
# Seems to work fine at the moment - usually the blacklist lags behind driver updates

sudo apt-fast install google-chrome-unstable

# Welcome to a hot rodded ChromeBook, faster than ChromeOS, it seems
# Why this way? I wanted to keep most of the Galliumos tweaks and live on the bleeding edge
