Where is the value that defines SCREEN stored?


In the effort to bring up XWin functionality, trial and error process reealed "export DISPLAU=192.168.1.101:0.0" to be the final setting.

Is there a variable or configuration file that defines the value that the variable "DISPLAY" must match in order to get X apps to work?

Is there a definition for each of the zeros in :0.0?
What is the difference between :0.0 and :10.0
would there ever be a case for :0.1 or :11.2?

Not sure, but I think the :0.0 are xy coordinates.
If you look in your xorg.conf, in the "Screen" section you should find somewhere:
Code:
Viewport   0 0
I think it's that.
Usually when I set my display I just put:
Code:
export DISPLAY=:0.0

Thanks for the response!
My xorg.conf lies in /etc/X11, but contains no "Viewport" and as you can see from below, the closest I come is the BusID "PCI:1:0:0" under "Device" --- the Sections for "Screen" and "Monitor" have no reference.
Like you I do "export DISPLAY=:0.0" and it works but there must be something to compare "DISPLAY" to in order to get a match.
I seem to have several files that contain xorg.conf in their names. What path are you using to locate your xorg.conf?
