cant start x programs when under root

Hello
I cant start x programs under root.
This is what i get when i wanna start xcdroast to configure it:

hylke@hylke:~$ su
Password:
root@hylke:/home/hylke# xcdroast
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Gtk-WARNING **: cannot open display: :0.0

Does anybody knows how to fix that?
Thanx Hylke

hi there...

you need to export the DISPLAY variable..

Code:

setenv DISPLAY $HOSTNAME:0.0

should to the trick..

It says:
root@hylke:/home/hylke# setenv DISPLAY $HOSTNAME:0.0
bash: setenv: command not found

my mistake!!
i didn't read that you use a bash terminal :cool:
you need...

Code:

set DISPLAY=$HOSTNAME:.0.0

hope it is correct now..
$HOSTNAME => you should give your machine name..

It still doesn't works:

Gtk-WARNING **: cannot open display: :0.0
root@hylke:/home/hylke# hostname

Hylke

trying again...

i am sorry for the delay... no experience with bash...
i tested now... :D

Code:

env DISPLAY=$HOSTNAME

regards

slackie1000

ps. you can test your environment variables in "bash" typing "env". You should see the DISPLAY corrected assigned.

Still doesn't work, but the display mode is (i gues) correctly set.

You are getting refused by the server. Try invoking
xhost +
to allow foreign connections to your X server before switching to root user.

After switching to root, you can set your $DISPLAY variable, if necessary, under bash by invoking:
export DISPLAY=hostname:0.0

Thanx
That xhost + did the trick.
