These sections are typically found at the websites of Linux distributions, and often contain a variety of helpful documents with information not easily encompassed within a FAQ. This is the second place to go when troubleshooting a problem. Look for sections with one or more of the following titles:
Installation Support
Knowledge or Solutions Databases
Tips and Tricks
Errata, Fixes and Updates
Security Information
Bug Tracking System
Bug Database
Hardware Guide or Compatibility List
Technical Guides
White Papers
Some websites provide a site search engine that will facilitate your quest for a solution.
If you have a problem with a newly installed distribution, look here first as bugs and their fixes are typically posted here. You may find a detailed guide that will help you accomplish a task such as upgrading your kernel or the version of the X Window System you are using.
I have often been able to solve problems with my Linux distribution by looking into the bug report database, and finding that another user already has offered a solution to this issue.
I recommend you spend some time at the website of the distribution you are using, familiarizing yourself with what is available.
