#chrubuntu

The Samsung ARM Series 3 Chromebook works (and dual boots) well with ChrUbuntu, and is stable. There is a lot of conflicting information on ChrUbuntu installation settings, and it's often not clear which model a particular post is in reference to. Below is what worked for me.

=====

First, I installed 12.04 LTE with all settings at default:

curl -L -O http://goo.gl/s9ryd; sudo bash s9ryd

You should now be up and running happily with Ubuntu. There are well documented solutions for the self-evident touchpad and audio problems, and also a Google Cloud Print app that works.

The only remaining unsolved mystery is that unless I shut down first, closing and then opening the lid always freezes up the device. The only recourse is to cold boot (hold down the power button until powered off, then press again to power on). This happens regardless of how long the lid was closed for, whether I was in command mode (Ctrl+Alt+F2) or not, whether I suspended the device prior, etc. Couldn't find a solution online. Any help will be appreciated.

Dual boot works a bit differently than you might expect: You will not be able to select your operating system of choice at boot time. The Chromebook will always boot into the same OS it was previously in, unless you tell it otherwise.

To reboot from Chrome OS into Ubuntu, run:

sudo cgpt add -i 6 -P 5 -S 1 /dev/mmcblk0; sudo reboot

To reboot from Ubuntu into Chrome OS, run:

sudo cgpt add -i 6 -P 0 -S 1 /dev/mmcblk0; sudo reboot

You can dual boot more efficiently by creating aliases.

In both operating systems under your home directory (~), create/edit your .bashrc file.

Chronos user on Chrome OS will need to use vim:

sudo vim .bashrc

Ubuntu can use gedit or whatever.

Add the following line to the file in Chrome OS:

alias ubuntu='sudo cgpt add -i 6 -P 5 -S 1 /dev/mmcblk0; sudo reboot'

Add the following line to the file in Ubuntu:

alias chromeos='sudo cgpt add -i 6 -P 0 -S 1 /dev/mmcblk0; sudo reboot'

About 6 months ago I decided to get rid of my iPad and old Windows computer, both of which found very little use for me, and experiment with a Google Chromebook. I won't talk about why I didn't like ChromeOS, you can do your own reading on the topic. But I want to share what I did to finally make my Chromebook usable running Ubuntu 12.04

If you have an ARM Chromebook with 3G access and want to put Ubuntu on it and also keep your 3G access, do the following:

If you haven't already, set up 3G in ChromeOS and make sure it works.

Install Ubuntu on an external drive or SD card

sudo apt-get install wvdial

Put this in your /etc/wvdial.conf after replacing the XXXs with your phone number that Verizon set up for you. You should have an email from them when you activated their free 100MB/month plan with the number in it.

Then run sudo wvdial.

You may have it do it a couple of times before you see pppd do stuff. You can exit out of wvdial, pppd stays running until you kill it.
