I assume you are working in textmode and you have never configured X.I have no information to go ahead.any way try using 'vi' and post results+more information here.

Ok ...
I am under X (kde ) so it hapened when i tried to start emacs into a console after i tape 'su' and 'password'

as 'user' you'll need to:
xhost +localhost
then:
su
then start your X app, then when you exit back to your 'user' make sure to:
xhost -localhost

Ok, I'm having this same problem with Debian Woody.

At first I thought I understood this. I even posted in another thread (someone having the same problem) describing how you have to run xhost as *you* but then 'su' to root to run your X program. But this really isn't working! Here's a little interlude of my efforts:

[john@baz ~]$ xhost
access control enabled, only authorized clients can connect

[john@baz ~]$ xhost +localhost
localhost being added to access control list

[john@baz ~]$ xhost
access control enabled, only authorized clients can connect
INET:localhost

[john@baz ~]$ su
Password:

[root@baz /home/john]# xcalc
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
Error: Can't open display: :0.0

[root@baz /home/john]# exit
exit

[john@baz ~]$ xhost -localhost
localhost being removed from access control list

[john@baz ~]$ hostname
baz.foo.com

[john@baz ~]$ xhost +baz.foo.com
xhost: bad hostname "baz.foo.com"

[john@baz ~]$

I think the "INET" in the xhost output is a clue...

Any ideas anyone?

xhost +local:root
