# outside chroot
DISP=:1  # adjust to suit your configuration
COOKIE=$(mcookie)
AUTH=$(mktemp)
echo "add $DISP . $COOKIE" | xauth -f "$AUTH"
echo "add these commands to clients:"
echo "export DISPLAY=\"localhost$DISP\""
echo "export XAUTHORITY=\"$AUTH\""
Xephyr -auth "$AUTH" -reset -terminate "$DISP" && rm "$AUTH"

And, inside the chroot, set the DISPLAY and XAUTHORITY variables as directed by the setup script and copy the "$AUTH" file from outside the chroot into the chroot to the path assigned to "$XAUTHORITY".
