I checked the security documentation for XFree86, but it is very difficult to understand how to deal with credentials. What is the best way to set credentials for my server?

If you have your server running already and you get "authorization
rejections" from clients they don't have anythoing to do with access to /dev/fb*. Your clients may not have the correct credentials to
connect to the server. For test purposes you can disable access
control entirely by specifying '-ac' on the server command line.
