[Message part 1 (text/plain, inline)]

I have this template which captures clipboard content in file. It works 
fine when emacsclient is running, but if no client is running then 
server adds empty entry.

(add-to-list 'org-capture-templates
       '("x" "Clips" entry (file+headline "/home/user/desktop/clips" 
"Clips")
         "** %x" :immediate-finish t :prepend t))


*System:* 5.10.16-arch1-1
*Desktop Environment:* xfce
*GNU Emacs 27.1*

I'm not quite sure I understand you correctly here -- but I think you're
saying that if you start "emacs --daemon", then that daemonised Emacs
can't communicate with the X clipboard?

I'm not sure, but doesn't that sound quite natural?  If you don't have
an X window open, then you can't talk to the X server, so you can't
access the clipboard, either.

I don't know how Org is talking to the clipboard, though.  Anybody?

I don't know if it will help, but I found workaround to capture X-clipboard.

Since %x doesn't work with daemon, I used %i and passed X-clipboard's
content using xsel. Like,

xdg-open "org-protocol://capture?template=h&body=`xsel`"

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I think the conclusion here is that this is working as it should, so I'm
closing this bug report.  If I misunderstood, please respond to the
debbugs address and we'll reopen.

Actually, that's not quite correct: Emacs can talk to the X server as
long as the terminal object remains available, but there is no way for
_other_ clients to ask for the contents of Emacs's selections if it
doesn't have at least one open frame that can be used as the owner for
the selection(s).
