Different versions of libreadline can essentially co-exist.
Also, libreadline does not seem to affect the DISPLAY environment.
Of course, if he has libreadlines he doesn't want, he should remove
them.
Anyway,

KDE-related, in your case. That's it;
DISPLAY=:0      (startplasma-x11)
When I got into plasma5 desktop, I have the followings which are
related with plasma5;
DISPLAY=:0	(plasma_session)
   DISPLAY=:0	(start_kdeinit)
   DISPLAY=:0	(kded5)
   DISPLAY=:0	(kwin_x11)
   DISPLAY=:0	(kglobalaccel5)
   DISPLAY=:0	(ksmserver)
   DISPLAY=:0	(xsettingsd)
   DISPLAY=:0	(kscreen_backend)
   DISPLAY=:0	(kaccess)
   DISPLAY=:0	(org_kde_powerde)
   DISPLAY=:0	(plasmashell)
   DISPLAY=:0	(kalendarac)
   DISPLAY=:0	(kactivitymanage)
   DISPLAY=:0	(akonadi_control)
   DISPLAY=:0	(kmail)
   DISPLAY=:0	(akonadiserver)
   DISPLAY=:0	(akonadi_akonote)
   DISPLAY=:0	(akonadi_archive)
   DISPLAY=:0	(akonadi_birthda)
   DISPLAY=:0	(akonadi_contact)
   DISPLAY=:0	(akonadi_followu)
   DISPLAY=:0	(akonadi_ical_re)
   DISPLAY=:0	(akonadi_indexin)
   DISPLAY=:0	(akonadi_maildir)
   DISPLAY=:0	(akonadi_maildis)
   DISPLAY=:0	(akonadi_mailfil)
   DISPLAY=:0	(akonadi_mailmer)
   DISPLAY=:0	(akonadi_migrati)
   DISPLAY=:0	(akonadi_newmail)
   DISPLAY=:0	(akonadi_sendlat)
   DISPLAY=:0	(akonadi_unified)
   DISPLAY=:0	(kioslave5)
   DISPLAY=:0	(kioslave5)
How about this way?
As an user,
1. $ DISPLAY="${DISPLAY:-:0}"; export DISPLAY
2. $ xauth add $DISPLAY . hexkey
Then,
3. echo $DISPLAY
OK, and here is what I saw -
...
marc@nova:~> DISPLAY="${DISPLAY:-:0}"; export DISPLAY
marc@nova:~> xauth add $DISPLAY . hexkey
xauth: (argv):1:  key contains odd number of or non-hex characters
marc@nova:~>  echo $DISPLAY
:0
HTHs  Thank you again for your assistance! Marc...
...
Regards.
