The members of the Ubuntu community have put together a great Desktop Course that covers Ubuntu 7.10 “Gutsy Gibbon” that can be a great way to learn how to do thing s in the latest version of Ubuntu.
According to the announcement on Ubuntu’s The Fridge
The 400 page book provides a thorough overview of the Ubuntu Desktop and is a great resource for Linux and Ubuntu newcomers.
In addition to the Docbook format using XML stylesheets, it’s also available in PDF files as a Teacher’s and Student’s Guide. The ten modular lessons are set up to take two days of instruction, but I’m sure you can use the Student’s Guide as a great way to learn at your own pace.
Ubuntu creator Mark Shuttleworth has come up with a great idea for producing training materials for both commercial and non-commercial use, and you can see what he has in mind on his blog.
You can get more information i the announcement on the Ubuntu Wiki, as well as links to the various versions. The course and it’s materials are released under a Creative Commons Attribution-Noncommercial-Share Alike (BY-NC-SA) license.
