Root user is not able to open "Users and Groups" screen

2
Hi All,

When I try to execute "system-config-users" as root user, I get following error:-
Xlib: connection to "hostname:2.0" refused by server
Xlib: No protocol specified

system-config-users requires a currently running X server.

When I execute "echo $DISPLAY", following is the output:-
hostname:2

When I execute "xauth list $DISPLAY", following is the output:-
hostname:2 MIT-MAGIC-COOKIE-1 618201fcedda089cda70353ec2019f66

xclock is also not working.

How can this problem be solved permanently?

Any help will be appreciated.

It looks like your hostname may be invalid. What does the 'hostname' command return?

I used this link for reference, it shows what the $DISPLAY variable typically looks like
