This question already has an answer here:
What is the difference between DISPLAY :0 and :0.0? On RedHat 5.8, I can right click the desktop to start a shell and DISPLAY will be ":0". If I go to the Menu-System-Terminal to start a shell then DISPLAY will be ":0.0". Can I always assume that these are really the same display?
For example, if I VNC in to a machine on DISPLAY 33, can I assume that ":33.0" and ":33" are the same display with the same permissions?
