If you running the X server as the same user you are trying to execute
"kdialog"  you might want to try this:

root:~#  kdialog  --msgbox "This is a test." --display `env |grep -i display |cut
-d'=' -f 2` 

or better instead of doing that [env|grep|cut] just use:

# kdialog --msgbox "this is a test" --display $DISPLAY 

which actually is what we want to get , the value for DISPLAY
environment variable. :)

[ instead of using "localhost:0" take a look at the DISPLAY environment
variable ]

If you are not running the X server as the user who wants to execute the

kdialog and you want let others [any] user from [any] host [ not recommended ] :
 $ xhost + 
 # export DISPLAY=:0.0 && kdialog... 

Other option would be ssh forwarding to your own box.
 $ ssh -Xf root@localhost 'kdialog --msgbox ......... '

I hope it helps,
