A new flavor of Ubuntu has been developed, and this one now runs on ARM Chromebooks. The release is still in alpha stages, meaning you can expect a few glitches and have some experimental features. You can run the OS in your Chromebook, but its still not recommended for daily work.

From the official blog:

Thanks to those who donated to the project, I'm excited to announce the first alpha release of ChrUbuntu 12.04 for the new Google Chromebook with ARM processor! This is an alpha release meaning there's a good bit of stuff that doesn't work yet.

Some of the things that still doesn't work yet are:

• Sound.
• The touchpad is still having glitches
• There is no Google Chrome browser for ARM yet. You can install Chromium though.
• Graphics are not accelerated as there are no drivers.

To install this in your Chromebook, you need to go to developer mode by pressing ESC and refresh keys while startup.

Some of the things that do work well are wifi connectivity, bluetooth, battery monitor and SD card.

Chromebooks are cheaper mobile devices that are meant to work on the cloud. You need to sign in with your Google account and work in Google drives. For work, you can use Google apps like Docs, Reader, Gmail etc.

ChrUbuntu is based on Ubuntu 12.04.
