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:
Knowledge or Solutions Databases
Tips and Tricks
Errata, Fixes and Updates
Bug Tracking System
Hardware Guide or Compatibility List
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.
