How can I know - X-server is running or not?

The fact is that I run the application (created with QApplication) and don`t know X-server is running or not. And my application say that "cannot connect to X-server" and crash!

What can I do to work normaly without crash?

You are sitting in front of your own computer, and if you don't even know if you have X running, sorry, no one else would...

You are in the wrong forum for such question. Your question has nothing to do with Qt.
A google search will give you a much quicker answer..

see the contents of the DISPLAY environment variable. If it's empty then you need to set it up properly (i.e. "export DISPLAY=:0"). "xhost +" may also come in handy.
