[SOLVED]Unable to run Graphical applications as root/sudo

Question

Ok so ive been working on getting my very first Arch install up and running and I need to get the catalyst drivers running for my HD6850 because I plan on doing some wine gaming.
So I followed the instructions here on the wiki for ATI catalyst and I now have the drivers up and running, tried glxgears and everything is fine. The issue I am having Is that when I go under the settings menu in KDE I have the "AMD Catalyst control center" there, however I do not have the (Administrative) option that I get with all other distros. I need to run the CCC as root to beable to configure my multiple monitors.
In a terminal when i enter;
sudo amdcccle
It returns with the following;
No protocol specified
amdcccle: cannot connect to X server :0
So after a little digging I found this thread on the ubuntu forums that was quite helpful;
http://ubuntuforums.org/showthread.php?t=307984
So I ran
DISPLAY=:0.0 xhost +
then tried again to run
sudo amdcccle
and like magic it worked and I was able to configure my displays.
However this is not a permanent fix. Can anyone see a more permanent solution to this issue? This affects more than just the Catalyst Control Center; It stops me from running any graphical application as root or with sudo. Also can anyone explain what is causing the issue?
I have searched to the best of my ability and as you can see I have for the most part fixed the issue, however I cannot seem to find a permanent fix, nor do I really know what caused the issue to begin with.

Answer 1

SOLVED
I took your advice about installking something like gksudo, and rememberd that on my kubuntu install I had something called kdesu. So Since im running KDE and not Gnome, I did some searching and found out how to install kdesudo using the AUR.
Just followed the install guide here for Yaourt ---> https://wiki.archlinux.org/index.php/Yaourt
Once I did that i just ran
yaourt kdesudo
selcted #1 and installed.
Now when I need to run a GUI based app as root I type in
kdesu <NAME OF APP>
So to solve my original issue I just run
kdesu amdcccle
instead of
sudo amdcccle
This seems to work for any app that needs to be ran a root with a GUI.
Also if your like me and you want to beable to just open CCC from your kickoff menu then do the following;
1. Right click kickoff > edit applications
2. Go to "Settings" > ATI Catalyst Control Center
3. In the Command Field add "kdesu" without quotes to the begining of the line so it looks like this
kdesu amdcccle
4. Save
