The X Windows System is a critical component in the Ubuntu operating system. X is not without its bugs, but fortunately debugging X issues is not rocket science.
The vast majority of Ubuntu X issues fall into one of several distinct categories, and based on the way they manifest, there are several different tactics that can be employed in a nearly paint-by-numbers fashion to isolate them.
Even non-developers can help! The goal of this handbook is to give folks a toolset for rendering these bugs easily solvable.
