X Server has crashed

I have terrible day. Problems are followed by other problems. When I was doing something on ubuntu system crashed and later when I restarted system this message appeared ( or maybe when I tried to execute "startx" command ):

I am really exhausted. I don't want to reinstall my system. I have to also say that earlier I reinstalled GTK and xlib. What should I do now ?
