<p>Security has changed at the PAM and selinix layers. In centos6 rot can't run startx with selinux in targeted mode. <br>
Most config gui are run as non-root and authentication is with a popup password box. So run the stuff as a normal user and wait for the prompt.<br>
RHEL7 will have selinux for X (partly at least).</p>

I can ssh -Y to a remote Ubuntu system, sudo -s, perform some<br>
commands including running X programs like gvim. It also used to work<br>
in Centos 5, however with Centos 6 and Fedora 14 it complains.<br>
<br>
E233: cannot open displayX11 connection rejected because of wrong<br>
authentication<br>
<br>
echo $DISPLAY tells me the variable is set OK.<br>
localhost:10.0<br>
<br>
I'm logging in via ssh from a Ubuntu system to Fedora (for<br>
instance). As a normal user I can display X programs fine, but when I<br>
sudo it doesn't work.<br>
<br>
My Centos 5 system does but my Centos 6 and Fedora systems don't.<br>
<br>
I'm sure it's some sort of security restriction but is there a way to<br>
make it work?<br>
<br>
Google wasn't much help or I didn't know how to phrase the question.<br>
Wonder if Evi would help?<br>
<br>
Thanks,<br>
Jim.<br>
