Overview

This is a guide to setup a native Linux install on your Eve Chromebook. I have chosen Ubuntu 18.04 LTS (daily snapshot) + Mainline v4.14 kernel as my target.

Setup

Enable Developer Mode
Install the latest SeaBIOS firmware (the stock firmware won't detect NVME hard drive)
- https://mrchromebox.tech/#fwscript
- Run the command in the terminal, and select the "Install/Update the RW_LEGACY firmware" option
- The script will ask if you want to enable USB boot by default, select YES. (So you can install a distro from a USB stick)
Download Ubuntu 18.04 LTS, and create a bootable USB drive.
Attach USB drive through a TYPE-C USB adapter, and reboot.
At the OS verification prompt, issue a CTRL-L and ESC and select the USB drive as the boot option.
Install the OS to the hard drive, the touchpad pressure sensitivity defaults are horrid, and life might be easier for you to use a USB mouse.
After the install is done, reboot, and boot the machine via Legacy mode off the internal hard drive.

Tweaks

Kernel

Install the latest released Linux Kernel - http://kernel.ubuntu.com/~kernel-ppa/mainline/

Touchpad

Fix the touchpad pressure sensitivity
- As root create a file at /etc/udev/hwdb.d/99-touchpad-pressure.hwdb
- My configuration is listed below, if you don't like it, knock yourself out - https://wayland.freedesktop.org/libinput/doc/latest/touchpad_pressure.html#touchpad_pressure_hwdb
```
libinput:name:*ACPI0C50:00 18D1:5028 Touchpad:dmi:*svnGoogle:*pnEve*
LIBINPUT_ATTR_PRESSURE_RANGE=15:35
```
- Once you have added the configuration, run the follow command to update
```
sudo udevadm hwdb --update
```
- Reboot

Backlight

Clone this repo, and run the scripts/backlight/setup-systemd.sh * This will install a simple service to enable and control the backlight
Reboot
Map the brightness
- Setting -> Keyboard -> Custom
- Increase brightness = /usr/bin/local/brightness --increase
- Decrease brightness = /usr/bin/local/brightness --decrease

Audio

Copy the dfw_sst.bin firmware provided in this repo to /lib/firmware
Add a blacklist entry in /etc/modprobe.d/blacklist.conf
```
blacklist snd_hda_intel
```
