Screen Display
Posted in PC Laptops by admin

Are there linux environment variables which represent each display screen?
I need a way to pipe (¦) a process to a specified display screen.
There should be an environment variable DISPLAY. If I type "env | grep DISPLAY" it returns "DISPLAY=:0.0"
The general form for the first display on a host is
host.ip.address:0.0
If you have a second screen attached, I think it would be
host.ip.address:0.1
I may be wrong. I know if I open another Gnome session using Switch User, the DISPLAY variable shows as
host.ip.address:20.0
