I dissabled seLinux & thistime refused to
download & install any updates to seLinux but yet again I am not able to run
the package updater or any other program that requires root access from my
user account. I am entering the password correctly & am able to login as
root in the terminal but when I type the command 'pup' for the package
updater I get the following:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
This looks like 'root' is not allowed to connect to the X-server,
because someone else (the regular user) is using it currently.
Logged in as the regular, does 'xhost +localhost' in an xterm resolve
that problem?
Alternatively, using 'kdesu pup' may help, but I've never tried it.

change to root in an xterm using su or su -, root is given a copy of
this "magic cookie". (There will be a file created in /root called
.xauth<something>.) This gives root access to the X server. If you
log in at the cli, without having changed to root in an x term, root
will not have a copy of the current cookie. Also, this "magic
cookie" is generated each time a user logs in using the gui, or
starts X from the cli. Each X secession has its own "magic cookie".
You can see what file contains the "magic cookie" by running
"echo $XAUTHORITY".
This is a security feature. You can man xauth for more details.
