displays :0, :1?


hello,
Im discovering the x windows system, getting info about the subject, and gathering questions.

Looks like the xorg is the server under the windows managers, which are under the "eye-catching" desktop environments.
am i right?

ok, xorg is a client-server application that can accept petitions in the same pc as its installed, or over the lan. right?

Now, interacting with VNC, i see ":1" which seems to refer to displays, i suppose that refers to graphical displays? is :0 -> tty1?
:1 tty2?



more questions to come, thanks.

No. Treat displays as virtual (not visible on the monitor) desktops. The :0 is usually copied to monitor, the rest are stored only in memory, but can be accessed through VNC client and displayed like :0 in remote application or switched back and forth on local monitor (like Fast Switching User feature in MS Windows).

Many desktop environments use multiple (typ. 4) desktops + sometimes other "locations" such as the background of the dektop cube animation or window flipping. Them all are still on :0

Now if you do a switch user you open a second X runing in parallel. The screen of this one is going to be :1

in this case, but not necessarily allways, Alt Ctrl F7 is getting you to :0 and Alt Ctrl F8 to :1

When sharing desktops over the network something might be different, I am unsure how it works in this case

so :0 is the same screen that a local user could be running, and :1 and :2..... are sessions like in windows terminal services?

Yep in this example one user is logged in locally and 2 others over the network
