Normally i can get started with the x window system at the commandline with command "startx". But i get in troubles after typing system-config-keyboard. Can somebody help me to troubleshoot my centos machine?

My configuration file was broken by system-config-keyboard.

This is my error-output and my xorg.conf ;
