kdialog error

Hi Guys,

I am getting the follwing error related to kdialog. It seems that it is not related to xlib since it is already installed.

Any idea?

root@linux:~#kdialog --msgbox "this is the test"

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kdialog: cannot connect to X server :0

You apparently are logged in as user, then did su to root and tried to run a graphical application as root, from the command line.

The correct procedure. As user, issue the command: xhost +localhost. Then su to root. Then run kdialog.

When you're done, exit to user prompt, then run: xhost -localhost.
