less /var/log/Xorg.0.log |grep security

error opening security policy file /usr/lib/xserver/SecurityPolicy

Actually, I have no idea what SecurityPolicy file is. I found this file in the /usr/share/doc/xserver-xorg-core/SecurityPolicy. (see Ubuntu forum)

cd /usr/lib
mkdir xserver
cd xserver

ln -s /usr/share/doc/xserver-xorg-core/SecurityPolicy SecurityPolicy

After restarting xserver, error message was gone.
