I think I'm misunderstanding this variable.

  1. Does each x-session have it's own display variable?
  2. What does the number before the dot vs. after the dot mean, for example DISPLAY=0.0
  3. Which number (before/after) represents an x-session?

Thanks :-)

Each X session has its own display number. This is the number before the dot. The number after the dot is the screen within the X session.

What is meant by screen? Does this mean physical screen like running two monitors or something else? – rubixibuc Feb 19 '12 at 4:58
    
That part is implementation-defined. On Xorg it means physical screens. – Ignacio Vazquez-Abrams Feb 19 '12 at 4:59
