Ubuntu Wiki

This set of wiki pages is primarily focused on assisting new Ubuntu X developers, packagers, testers, and bug triagers.

While there are some links here that may be useful to end users experiencing difficulties or power users want to learn more about X, you may find end-user-focused tips and aids available on the Video Resources page at help.ubuntu.com more suitable.

There are notes scattered about in the wiki comments. These may be removed as the work is done.
