I am using Red hat 9 which has been newly installed.I am having problem evoking "emacs" as the user.I tried through root and it worked fine.
Whenever I start it as the user it gives me the following message :-
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
emacs: Cannot connect to X server :0.0.
Check the DISPLAY environment variable or use `-d'.
Also use the `xhost' program to verify that it is set to permit
connections from your machine.
Any help in this regards will be appreciated
