I can't open gui program in KDE as root


When I use "su" or "su-" to change to root, I can't run GUI program, if I type /opt/kde/bin/kwrite, it shows:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
kwrite: /opt/kde/bin/kwrite
root@perfect:/home/shad# /opt/kde/bin/kwrite
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kwrite: cannot connect to X server :0.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

How can I run GUI program in KDE as root?

Do the following,

Code:
$xhost +hostname (e.g. localhost)
$su
#kwrite
or just
$su -c "kwrite"
You could also just do
Code:
$kdesu kwrite

Thank you!
What's the meaning of "xhost +hostname"?

The "xhost +hostname" command allows a user who didn't start the X server, to run a gui program in your current X session from the host you specify.
