While I've never seen this error before, I did a search online and found this from x.org.
Maybe you can find some type of answer there?
I'm unable to post links in reply's, but x (dot) org wiki faq has a ton of answers to problems like this.

This means that the Xserver cannot find a configuration file because it has not been properly configured. Please check
FAQMiscellaneous for information how to configure your Xserver.
Another reason for this error may be that you have created a configuration file but it is not in the correct location. The Xserver checks for configuration files at different locations. The usual locations are: /etc/X11/xorg.conf or /etc/X11/XF86Config-4.
Another reason for this message may be that your Xserver cannot read the file because the server binary has the wrong permission. On UN*X like systems the server is usually owned by root and runs with the SUID bit set so that it runs with root privileges even if started by an ordinary user. Therefore it should be able to open the configuration file regardless of who owns it or of its permissions. Please check "How do I check if my server bianry has the correct permissions?" on the
FAQMiscellaneous page for futher information
