Hi there!

I think this a bit more general question, not special KDE but I think its ok in here, if not.. please let me know, and sorry :-)

When I work in DKE a a normal user and become root in the console using "su" I cannot start any programm using X-Server...

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

is what I get ...

Can someone help me along with that?

Thanks, greetings, Sascha

The permissions to open an X window are independent of the UNIX permissions ("I am root, I can do everything" is not true here.).

- If you're alone on your machine and high security is not a priority you could say: "xhost +localhost" on the command line. This allows access to any user on your local machine.

- Alternatively, if you're running an sshd that allows root logins (again a security question) you could use "ssh -X root@localhost" instead of "su - root". This uses the X11 forwarding feature of ssh.

- There's also the kdesu program: Try "kdesu yourprogramname" on the command line.
