Install Linux OS

Edit 0 1 …
These are instructions to setup both your Chromebook and your EV3 so you can use Linux. We will also install Python and related software. Some common tasks like copying files and running programs are also covered. Things you need to type are indicated by a change in font. When you type a command you will need to follow it by pressing the enter key.
Chromebook Developer Mode
The first step is to enter Developer Mode. This will ERASE THE CONTENTS of your Chromebook! BACKUP everything you want to keep! More details at http://www.howtogeek.com/162120/how-to-install-ubuntu-linux-on-your-chromebook-with-crouton/.
  • Enter Developer Mode (hold down escape and refresh, tap power button).
  • Press ctrl-D at recovery screen.
  • Press enter to accept that OS verification is OFF.
  • Press ctrl-D at warning screen (or wait 30 sec.)
  • Setting up Developer Mode will take a few minutes. Go get some coffee. Grade some homework. Play with the cat... It will beep at you when it is done.

Setup Chrome
  • Pick a language (probably English).
  • Select US keyboard.
  • Select the network:
    • o SSID:
    • o Password:
    • Click Continue.
    • Accept Google Terms and Conditions.
    • Enter g-mail address.
    • Enter password.

Install Crouton
  • Open Chrome browser and go to http://goo.gl/fd3zc. This will download the Crouton installer script. Click "Save."
  • Press ctrl-alt-T to open Crosh developer shell.
  • Type the this command followed by the enter key: shell
  • Type: sudo sh ~/Downloads/crouton –e –t xfce
  • You will be asked to create two passwords (they can be the same). You will need to type both of them twice. Be sure to remember them. These instructions will call them password 1 and password 2. You will not see the passwords as you type them.
  • It will ask you to move the mouse (track pad) for a few seconds (to generate random numbers for security).
  • Again this will take a few minutes. Get more coffee. Grade more homework. Annoy cat…
  • You will be asked to supply a user name and yet another password (again you can use the same password if you like). We will call this password 3.
  • You are now ready to start Crouton by typing: sudo startxfce4
  • You will be asked for two passwords. These are passwords 1 and 2.
  • Select "default config".
  • Sit back and admire the Linux desktop.

Switching from Linux to Chrome
  • To switch back to Chrome use ctrl-alt-shift-back
  • To switch back to Linux use ctrl-alt-shift-forward

Restarting Chromebook
If for some reason you need to restart the Chromebook you need to make sure you keep it in Developer Mode. If you leave Developer Mode you will ERASE EVERYTHING on the Chromebook!
  • Power on the Chromebook.
  • DO NOT PRESS SPACEBAR!
  • At the warning screen you either need to press ctrl-D or wait 30 sec.
  • Log into Chrome
  • If it is not already open, use ctrl-alt-T to get Crosh terminal.
