Hi, I just installed Suse 9.1,

When I'm not logged into root, I can access the X-server easily.

But when I'm root, it won't let me

linux:/usr # emacs hi
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.

Can someone help me set up the X-server for root?

Sorry I'm a newbie ^^;;

as your normal user, run "xhost +root@localhost"

I tried that but now I get this error:

tony@japan:~> xhost +root@japan
root@japan being added to access control list
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 109 (X_ChangeHosts)
Value in failed request: 0xfe
Serial number of failed request: 7
Current serial number in output stream: 9

Run "xhost +" to disable xhost authentication. Though not very secure, it's the easiest way to deal with this in my experience.

PFY

I get similar errors with 9.1.

I have always received that last "WARNING" in previous SUSE versions. But I have always used xhost +localhost.

I ran into the same problem under Gentoo. All of the following worked:

1)
su - root
xauth merge ~youruser/.Xauthority

2)
su - root
export XAUTHORITY=~youruser/.Xauthority

3)
ssh -X root@localhost
