--- Comment #18 from Dr. Werner Fink ---
To get DISPLAY and XAUTHORITY this requires some tricky bash environment which
depends on the display manager as well as on the sudo configuration.
In my /etc/sudoers.d/werner I'm using
env_keep+="LS_COLORS LS_OPTIONS DISPLAY"
then in /root/.bashrc the lines
if test -n "$SUDO_USER" ; then
SUDO_HOME=$(eval echo ~$SUDO_USER)
if test -n "$SUDO_HOME" -a -s "$SUDO_HOME/.bashrc.root"; then
export BASH_ENV="$SUDO_HOME/.bashrc.root"
. "$SUDO_HOME/.bashrc.root"
fi
fi
and in my $HOME/.bashrc.root
if test "${DISPLAY%[0-9]*}" = : ; then
for auth in /var/lib/xdm/authdir/authfiles/A${DISPLAY}-* /run/sddm/\{* ;
do
test -e "$auth" || continue
XAUTHORITY=$auth
break
done
if test -e "$XAUTHORITY" ; then
export XAUTHORITY
else
unset XAUTHORITY
fi
fi
... and if gdm is used this may adopted to the locations where gdm stores its
authority files
