It is clearly written in my message, in fact in imported it from the checkX
documentation. What part of the problem I'm describing is not clear to you?
"DESCRIPTION
Determines if X is installed, Xserver is running on specified DISPLAY
and will accept clients. Returns 0 if yes, nonzero otherwise""
In fact:
checkX :0 returns a false when, but the X11 server on :0 will accept
client requests.
Exporting DISPLAY=:0 and running emacs, for example, demonstrates that X11 is
available and accepting clients.
