Want to run Ubuntu on your Atrix? XDA forum member Sogarth has posted how to get a relatively easily upgradable Ubuntu on the Motorola Atrix.
The XDA member states it’s not perfect but close enough for other to start having a play around with it.
Please note that there is a very real chance that you will either soft-brick your device or get into an infinite reboot loop. The XDA member is however planning to write script that will automate most of the many steps required.
You will need a rooted Atrix, and some kind of terminal access. If you choose to use LXTerminal on the webtop, you’ll need some form of sudo access as well.
