'Trouble with XSetSelectionOwner
I have an application in which one opens many windows. I added copy/paste, using XA_PRIMARY.
That works fine within my application. It also works fine when copying from other applications (pluma, FireFox, mate terminal) into a window of my application.
When I call XSetSelectionOwner(), with time stamp etc as explained in the documentation, server acknowledges new owner. That is, XGetSelectionOwner() returns the owner I just set.
However, when copying from my app to other applications I do not receive SelectionRequest.
From what I see, server only sets the owner for the Display used in the call XSetSelectionOwner().
Is this how it is supposed to work? Then, is there something else to do so server sets owner for all apps?

Given the behavior of the Server, I had to assume that other clients are not making their request for "PRIMARY". So, I added "CLIPBOARD", and now everything is working great. The documentation appears to say that every client will use PRIMARY. Further reading seems to indicate that there is a difference between making a "selection", and "copying text". They seem to skirt this as a useful feature. I see nothing but confusion. Anyway, there really was no bug in my app. I think documentation should have a line saying: You must implement both, PRIMARY and CLIPBOARD. That was the problem.
