Fatal error while trying to use X11 in Cygwin...

Hello, I have just installed Cygwin and it works for what I really need to do. However, when I want to try "X11" with the command "x", a fatal error occurs. Could you help me please? Thank you very much, Philip (novice user of Linux- and any other related things...)
