[LINUX_Newbies] root can't access X in su session

 

I feel really dumb about asking this, but most of the time I have a
terminal open with several tabs. Tab #1 is always running a su session
so that I can do my daily backup maintenance. Every time I try to use
any X app under the su, I get this:

oot@caitlyn:/backup/caitlyn/201612# file-roller
caitlyn-slackware-michael-20161220.tar.bz2
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings
will not be saved or shared with other applications.
No protocol specified

** (file-roller:16500): CRITICAL **: Failed to parse arguments: Cannot
open display:
root@caitlyn:/backup/caitlyn/201612#

I've tried running xhost + and xhost +localhost before issuing the su
command. I'm on Slackware. Very new to it as well. Any help would be
appreciated...
