How to connect to GOGO In Air Free WiFi (12 Free Passes) for your Chromebook

If you were lucky enough to get 12 Free passes to GOGO WiFi when you purchased your Google Chromebook (like I was) this will tell you how to redeem them.

You must have your Chromebook with you on the plane to obtain the free passes.   GOGO and Google decided to track your passes automatically via your laptops hardware address AKA MAC address.   The MAC address is in the TCP/IP packet that traversed the GOGO network.   You do  not obtain physical passes or any codes of any type.   Just access the WiFi on the plane and they will allow you to connect.   If you have any issues you can Instant Message the GOGO support team and they will assist you while you are on the plane.

Thanks Deric for you help getting online with GOGO.

Samsung Chromebook remains Amazon Top Seller

The Samsung Chromebook is the best selling 'laptop' at Amazon.   I think a better description is 'tablet with a keyboard'.

And the Chromebook really excels in that area.

Ubuntu on Chromebook - How to get the speakers working

If you are having difficulty getting the speakers working with Ubuntu installed follow these steps

Out of the box the sound sources are 'muted' so it is just a matter of unmuting them. Here is what I did in detail (pay attention to matching Left with Left and Right with Right, otherwise you might end up with swapped channels).

1. Open a Terminal (ctrl-alt-T) type 'alsamixer' and hit enter

2. Top left of the terminal make sure that '[Playback]' is highlighted in yellow, either hit the 'Tab' key to cycle through, or 'F3' (refresh button) to select it.

3. Press the 'm' key which will toggle un-muting/muting for that specific Item. There are many options in alsamixer so you have to read carefully for the correct items listed in items 4 and 5. 

4. Left Speaker Mixer Left DAC1

5. Right Speaker Mixer Right DAC1

6. After you've enabled all these channels you should test them.

7. Use ALT-Q to exit out of AlsaMixer

How to install Ubuntu on Samsungs new Chromebook (notebook 303C)

 By Sloan Miller

Following these steps will result in Ubuntu 12.04 LTS for arm processor being installed on a new Samsung Chromebook 303C.   The sticker on the bottom shows 'Model code WE303C12'.

This $249 Google Chromebook is covered below


I wrote this blog post because I found relevant information scattered around the web and knew it would be useful to have much of the relevant information in one How To Guide.

The install guide shows clearly the step by step process with other very important information like the sudo password once installed.  Remember Ubuntu does not come with a root password set.

These are instructions to install Chrubuntu on the new Samsung Chromebook. When finished you will have Chrubuntu installed on a spare SSD Drive that plugs into the left side of the Samsung. The ChromeOS SSD will still contain the ChromeOS alone. To boot into Chrubuntu you will press CTRL-U.

http://www.google.com/intl/us/chrome/devices/landing.html

I removed all partitions with fdisk on the SD-card. Chrubuntu would not install when there were partitions on the sd card. Your mileage may vary.

The Chromebook needs to be in developer mode.  This step will reset the Chromebook to factory default settings.  This did not appear to affect anything as all work I do is in the cloud and all of my browser settings are stored by Google for Chrome.

Steps to enter developer mode:

To invoke Recovery mode, you hold down the ESC and Refresh keys and poke the Power button.

To enter Dev-mode (developer mode) you first invoke Recovery, and at the Recovery screen press Ctrl-D (there's no prompt - you have to know to do it). It will ask you to confirm, then reboot into dev-mode.
Dev-mode works the same as always: It will show the scary boot screen and you need to press Ctrl-D or wait 30 seconds to continue booting into ChromeOS.

More info related to developer mode:

http://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices/samsung-arm-chromebook
 
I was in developer mode when the installation was performed.
 
Boot up to the first Chrome OS graphical screen aka Login Screen. Don’t login to the OS. Make sure that the Chromebook had associated with the wifi Access Point. This is done by clicking on the wireless icon in the lower right corner. As we need to download packages during the install process.


Log in as a guest and open the Chrome browser. Once the browser is open hit the ctrl + alt + 't' keys. That is hold down the ctrl key, the alt key and the letter t key all at the same time.


You will then see a:


crosh>


prompt. I'll bet this stands for Chrome Shell. If you type in shell you will be inside the shell for the ChromeOS.


crosh>shell


and you will see


chronos@localhost / $


This is the prompt to the Operating System.


The wget command is used is as root to download the Chrubuntu packages. This step takes 30-45 minutes. Be very careful when entering the /dev/mmcblk1, if you do not follow the directions closely enough you can install on the internal SSD drive and that will result in needing to reinstall the ChromeOS.
 
wget http://goo.gl/34v87 ; sudo bash 34v87 /dev/mmcblk1

chronos@localhost / $  wget http://goo.gl/34v87 ; sudo bash 34v87 /dev/mmcblk1

Once install is complete on reboot hit CTRL-U immediately. This will boot into chrubuntu. The root or sudo password in chrubuntu is user.


You can open a terminal to update Ubuntu. This is a good idea as a good number of packages were updated.
 
sudo apt-get update


You can also update Ubuntu via the GUI.


Then to listen to audio in the headphones and not on the speakers I turned on audio with alsamixer. I decided not to play audio through the speakers due to warnings on various webpages discussing the fact that internal speakers may melt. I also read that melting the samsung speakers may not longer be an issue but I decided not to risk it.


open a terminal and type


sudo alsamixer


Then scroll through the options with right arrow until you come across


“Left headphone Mixer Right DAC1” press letter m on keyboard to activate audio

“Right headphone Mixer Left DAC1”


Then press the letter “m” on your keyboard to activate. Its possible to do this for the built in speakers. It would be best to search for people who have melted their speakers before you proceed that turning on the builtin speakers.
 
After install I noted that the Unity Interface puts a large amount of overhead on the System. I decided to go with the Gnome Interface.


sudo apt-get install gnome


On reboot you will need to click on the small Ubuntu Icon near the login window. This is where you select Gnome.
