I am having a problem and I dont know where to start looking as far as fixing 
it. Here goes
as root (logged in as root not su) I can open and run any gui but as user I 
can run most progs but there are some that will not open. If I console and su 
then enter the prog name it still wont open---but in the root window it 
will--   as user doing su  I get the following 
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Gtk-WARNING **: cannot open display: :0.0
Now I am at a loss as to what to reset or adjust. I realise it is something 
that I have done inadvertely but cant seem to figure out what. I believe that 
when I was doing an apt-get  dist-upgrade it may have called for a 
configuration that I overlooked or misunderstood and the settings were 
changed. I say that because once upon a time everything was working fine. I 
just dont know what to look for. When I looked in the x11 and x config files. 
When I looked in /etc/X11/xserver there was a file -- security policy but all 
it addressed was sitepolicyA and B and C but nothing as to what A B or C 
policy was/were.
/etc/X11/Xresources doesnt address anything concerning permissions that I 
could find. I just dont know what was altered or where it is. I would 
appreciate any help. 
Installed is Libranet but the dist-upgrade has altered it to KDE3.0.5a and 
changed the basic Libranet settings but because it is still Debian ( sid ) I 
would assume the the settings would remain, they havent and it was an 
oversight on my part.]
I dont really understand this but I did try   chmod u+s /usr/X11R6/bin/X
and that hasnt helped. Ive been reading google for most of the day and now Im 
more confused then when I started.
Any suggestioins/help??
