[CLUG] Magic-Cookie

[Jerome KIEFFER]

Hello,

I have a small problem but I cannot solve it, so maybe someone knows the
solution :
when I running X, and I change the user (su SomeoneElse), I am not able
to run any X-client (netscape). The computer answers :

Xlib : connection to ":0,0" refused by server
Xlib : Client is not authorized to connect to Server
Error: Can't open display

Does anybody know about it, or about the MIT-MAGIC-COOKIE? is it related
to the permission of  the X-server ?

Thanks .
