HOWTO: Bodhi Linux on Samsung ARM Chromebook

The battery recently died in my old Asus Netbook which gave me some fire to finally get together a functional filesystem for the Samsung Chromebook I've had for a little over a year. I published a rough file system with install instructions here last December. Since then a few things have changed in the structure of ChromeOS and the install script/file systems needed some updates.

The following instructions install a Debian Wheezy based ARMHF file system with the Bodhi branded E17.6 desktop powered by the EFL 1.8.4

It is also worth noting that this updated installer script now supports installing the file system to an external media. When you run the second command in step three, simply provide an install target as the first argument (such as /dev/sda for a flash drive) and then press ctrl+u to boot tell the Chromebook to boot from an external media at start up.

Please note following these steps WILL permanently delete all local data and configurations of your ChromeOS! It essentially restores the system to factory defaults.

Step 1 - Boot in Recovery Mode

Make sure your chromebook is off. Then hold the escape and refresh keys (where f3 should be) and power on the device. This should get you to a recovery screen - press ctrl+d followed by enter. The system should now reboot into recovery mode.

Step 2 - Get to a TTY with Internet

Once the system reboots in recovery mode it will take a few moments to get everything configured (this requires no user input, just waiting - so grab a snack). Once the system starts up select a wireless access point to connect to, but do not log into a Google account. Now that we have an internet connection you need to drop to a TTY. To do this press ctrl+alt+-> (The "->" key is where f2 would be on a standard keyboard).

For the username type chronos and then press enter - no password is needed.

Step 3 - Download and run Bodhi installer

From the tty run:

wget http://goo.gl/HFG6a

Followed by:

sudo bash HFG6a

Both of the above commands are case sensitive so make sure you type them correctly! After running the second command you will be provided with some information about your Chromebook - press enter to continue.

Step 4 - Choose how much space you are giving Bodhi

The installer will prompt you for how much space you want to give to Bodhi. Enter an integer amount for how many gigs you would like to give Bodhi. On the 16gig smartbook the most I would recommend giving to Bodhi is 9gigs (with the max being 10).  For reference the base Bodhi install occupies around 1.6gigs. Once you select an amount of space to give Bodhi the drive will be re-partitioned automagically and then your system will restart. When it starts back up again you will need to walk through the ChromeOS setup process once more - again get as far as the Google login screen but do not log in.

Step 5 - Getting the Bodhi Filesystem

Get to a TTY again by following the instructions outlined in step 2 once more. Then run the same two commands provided in step 3. This time the Bodhi installer will see your drive has already been partitioned and it will begin downloading the Bodhi Chromebook image which it will then install. Note that this will take awhile depending on your internet connection speed as a 300MB tarball needs to be downloaded and extracted. After it finishes installing your system will reboot and you will be greeted by the Enlightenment desktop!

User Information

Default username:

armhf

Default password:

bodhilinux

The default user has sudo rights.

Getting back to ChromeOS

If you need to get back into ChromeOS after installing Bodhi on your Chromebook - don't worry it is still there. In a terminal client on Bodhi run:

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

Once you are done with ChromeOS you can run the following in the ChromeOS TTY to get back to Bodhi:

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

Notes

I am really happy with the state of this image. Audio works, screen backlight is functional, Chromium browser works, and Flashplayer works. Sadly opengles still escapes me, but I have no need to play games on my netbook.

Wrapping Up

As always, please do not post support requests here! Please direct them to the ARM section of our forums. I'd also like to say many thanks to Bodhi community member Seekamp for posting here about the many improvements he came across in the last year for Bodhi on the Chromebook.

Cheers,

AT&T Connect to Cell System Review

This is a post written by me on behalf of Advanced American Telephones. All opinions are 100% mine.

My wife and I moved into a new townhouse a few months ago and our current cell phone provider (T-Mobile) does not get the best service in our new home. We have found a few spots in the house that get reception, but the rest of it is a giant dead zone. The basement is absolutely out of the question for reception, which I believe is likely an issue for a lot of people.

This past week we acquired a Connect to Cell System by AT&T (CLP99383) and so far we are very impressed with the results. The system is reminiscent of the average landline cordless telephone system but it integrates with cellular devices. Our system includes the main base, two additional charging bases, and three cordless handsets.

This system seems to have solved the biggest issue with our mobile devices - no service. The system uses bluetooth technology to connect the mobile device to the phone system. We simply have to leave our cell phones in a non-dead zone in the house and then we can use the handsets anywhere else in our home to send and receive calls using our mobile numbers/plans.

Ease of Setup: While my wife is by no means technology-illiterate, she had the system set up and working in just a few minutes without reading the instruction manual. The menus are intuitive and display on-screen instructions when connecting a device via bluetooth. The system supports being connected to up to two mobile devices at once (and a landline if anyone still has one of those).

Not Carrier/Device Exclusive: The system is AT&T branded, but worked with our T-Mobile devices and a friend's Verizon device seamlessly. Further, the system didn't have an issue working with my wife and friend's newer Android devices or my older Nokia N900. So long as your mobile supports a bluetooth headset it should work with the connect system.

Push to Talk Feature: The handsets and base are equipped with push to talk technology, creating an intercom system/walkie talkies for the house (It will be great not having to run up two flights of stairs to have a quick conversation).

Does not improve cell reception: The unit does not increase the reception that we receive in our house, so our phones still only work in certain areas, however the simple solution to this is that we have the base unit set up in an area where we do receive good reception and we leave our mobile devices next to it when we are home. The connect base even has a USB charging port built into it so our mobile doesn't run out of power while connected.

We then have the other units on the other two floors of the house. Leaving our mobile devices near the base ensures a good bluetooth connection (the instruction manual advises a 15ft. maximum distance)

Connect to Cell App: For Android devices, there is an app available in the Google PlayStore called "Connect to Cell." When used, the system will create an alert whenever your mobile device receives a text message, email, or social media update.

Additional Handsets: My home only has three floors, so I only have two extra handsets in addition to the base. If you have a need for more handsets than this the system supports connecting up to twelve at once.

Closing: Over all I am pretty happy with the Connect to Cell system. It allows me to have the feel of a traditional home phone system without having to pay for an additional service. It also provided a clean solution to having a lack of reception in certain areas of my house.

Cheers,

eAndora - Pandora Internet Radio Client - 1.0 Release

At the start of this year I posted about eAndora, a Pandora Internet Radio client I was working on that is written in Python and Elementary. Today I'm happy to announce that eAndora is finally feature complete enough for me to stamp something as a "1.0" release.

You will always be able to find the latest eAndora source release on source forge here. If developmental code is more your preference you can always find my latest work on github here.

I've tested this release with the latest releases of the Enlightenment Foundation Libraries (1.8.3), Elementary (1.8.2), and Python EFL (1.8.0). It could very well work with previous releases of these things though - for best results always use the latest versions.

If you have any questions feel free to drop a comment below. If you are a Bodhi Linux user the eAndora 1.0 release is currently in our testing repository and will move into the stable branch in January once the EFL 1.8.x series makes its way to stable.

HOWTO: Watch Netflix on Bodhi Linux

Not being able to utilize the Netflix video streaming service has been an issue on the Linux desktop for the past few years. This is due to the fact that Netflix utilizes Microsoft's Silverlight technology for video playback.

For the last few months though we have been able to watch Netflix in our native browsers on Linux using a Wine pluggin wrapper called Pipelight. Today I would like to walk you through the short process of using Pipelight to watch Netflix under Bodhi Linux.

Step 1 - Install Chromium or Firefox

Pipelight needs Chromium or Firefox to work. So if you are still using Bodhi's default browser Midori - you will need to install one of these other two browser. You can obtain your browser of choice by clicking on one of the links below:

Install Chromium Browser

Install Firefox Browser

Step 2 - Install Pipelight

Next we need to install the Pipelight plugin by clicking on the link below:

Install Pipelight

Pipelight depends on the Microsoft corefonts package. This means that if you do not already have these fonts installed they will be installed as part of the installation of Pipelight. When installing these fonts you need to agree to an EULA, to navigate to the Accept button you will need to use the tab key, and then press the enter button to select it.

Step 3 - Setup a User Agent Changer

The User Agent is a little code in your browser that tells the page you are viewing what browser you are using. In order for Netflix to even offer us the Silverlight player it needs to think we are on Windows. To do this we install a user agent changer browser plugin. Install the proper plugin linked below for your browser:

Chromium User Agent Changer

Firefox User Agent Changer

After you have the user agent changer installed - set your browser to detect as "Windows Firefox".

Step 4 - Watch Netflix!

Enjoy! If you have any questions or issues feel free to drop a comment below or open a support request on the Bodhi user forums.

Cheers,

HOWTO: Test E18, EFL 1.8.0, and Terminology 0.4.0 on Bodhi Linux

As of this past weekend the testing builds of the Enlightenment window manager DR18 (E18 for short) are in the Bodhi Linux testing repository. The following are the steps you need to take if you would like to install and help test the future of the Enlightenment desktop on your Bodhi Linux install.

Step 1 - Add the testing Repository

First we need to add the testing repository to our software sources. Open our sources.list with sudo using the following command:

gksudo leafpad /etc/apt/sources.list

Towards the bottom of the file you will find a line that reads:

deb http://packages.bodhilinux.com/bodhi precise stable

After the "stable" component we want to add the "testing" component. To do this we edit the above line to be:

deb http://packages.bodhilinux.com/bodhi precise stable testing

Save and close the file.

Step 2 - Upgrade to EFL 1.8.0

Open your terminal emulator of choice and run the following command:

sudo apt-get update && sudo apt-get dist-upgrade

This command will tell you that it wants to remove a number of packages (ecore edje eet eeze efreet eina eio embryo emotion eobj ethumb evas). This is fine - all of these packages have been merged into one "efl" package. Let the upgrade command complete.

Step 3 - Install E18

The default "enlightenment" package in Bodhi Linux will remain as the DR17 desktop - we will not be forcing anyone to upgrade to E18 so long as E17 still builds with the latest Enlightenment Foundation Libraries. This means to replace E17 with E18 we need to install the E18 package. In your favorite terminal run:

sudo apt-get install e18

It will tell you it wants to remove the "enlightenment" package - let it. After it finishes installing you should restart your desktop environment. 

Congrats, you now have the E18 desktop to play with!

A few Notes

I would like to remind everyone that this is pre-release software and you should expect to encounter issues. You can report/discuss the issues you are having in the testing section of the Bodhi forums.

At this current point a number of the extra modules (such as places and the engage dock) that the Bodhi profiles use are not currently built for E18. We will be working on adding support for these over the next few weeks.

In this same vein - a number of the existing E17 themes will have issues running under E18. They will all need updates to function with the latest version of the desktop. So when trying to confirm bugs it is always best that you are using the "default" E18 theme when testing things.

If you run into issues getting the testing repo added or the software installed I would encourage you to please open a thread on our user forums as opposed to simply posting a comment below. It is much easier to debug software issues on a forum than in a comments section.

Cheers,

~Jeff Hoogland

Bodhi Linux 2.4.0 Released

It has been close to six months since our last Bodhi Linux release - far too long! This is just our normal update release - meaning if you are already a Bodhi user and have been running your system updates then you already have all these additions running on your system!

To cut right to the chase - you can find direct downloads of the ISO images on Source Forge here. You can obtain torrent downloads for the ISO images later today.

Before I talk about the small details of this release, I'd like to remind folks that Bodhi is moving to a three times/year update cycle as opposed to the previous four times/year updates we'd been doing. Since E17 stabilized we have less of a reason to power out ISO images as often. Expect new releases in January/June/September from now on.

Also - can you believe it is almost the end of 2013 already? That means Bodhi 3.0.0 is less than twelve months away! It will be out sometime in the summer after Ubuntu 14.04 releases.

Back to the here and now - our 2.4.0 release features three ISO images to install from:

• 32bit featuring a current PAE enabled kernel
• 32bit featuring a non-PAE kernel with older hardware support
• 64bit featuring a current kernel

This release features the E17.4 desktop, version 0.5.5 of the Midori webrowser and the 3.8 Linux kernel. As always - our default theme selection is shaken up.

On a non-Bodhi related note, I'd like to apologize for the lack of new content on my blog for the last few months. Between moving, a new position at work, keeping my wonderful wife happy, and trekking all over the US for my hobby I haven't had nearly as much time to keep up with the latest technology. Hopefully I can find some time in the future to give my musings on things again.

Python - Sorting Lists inside of Lists

In some recent python code I was playing with I had the need to sort a bunch of lists based on elements within their elements. Thankfully python's built in sort function is plenty powerful and allows us to do this in a fairly easy manner. So for example if we have a list all of whose elements are also lists:

mylist = [["derp", 1, 7], ["bleh", 2, 0], ["merp", 0, 3]]

By default when we call the sort function on this list it will sort the sublists based on their first element in lexicographic order. For example:

mylist.sort()
print mylist
[['bleh', 2, 0], ['derp', 1, 7], ['merp', 0, 3]]

What if we don't want to sort these lists based on their first element though? By using the key argument we can sort our sublists based on any element we want. For example to sort the lists based on their second element we would use:

mylist.sort(key=lambda e: e[1])
print mylist
[['merp', 0, 3], ['derp', 1, 7], ['bleh', 2, 0]]

Or their third element:

mylist.sort(key=lambda e: e[2])
print mylist
[['bleh', 2, 0], ['merp', 0, 3], ['derp', 1, 7]]

Special thanks to the folks over at #python on freenode for helping me figure this little bit out. They are an extremely resourceful bunch. You can learn more about working with python lists here.

Cheers,
~Jeff Hoogland
