root-programs in chroot wont work

[poulerik <poulerik@pea.dk>]

Hi

I have a problem with running X-programs as root in chroot-inviroment. 
Things work well when i am a normal user, but when i try running from 
root for instance synaptic i got the following
error:

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


(synaptic:21355): Gtk-WARNING **: cannot open display:

I have also tried running as gksu but that wont work either.
It shows som wierd error message:
Failed to fork new proccess:no such file or directory

hope sombody can help
Thanks in advance
