title: How to start linux with gui without monitor?
body: <p>I met a problem.
  I had a server which is installed redhat enterprise 5.5.
  And one Qt program was running on this server.
  So what I should do is to turn on my server, the server will start automaticly with Gui and that Qt program will start automaticly.
  I finished all on my desktop.
  But while I start this server without monitor, we know server was running without monitor,the X server go bad.God, what should I do?</p>

  <p>I searched on internet,somebody told me that I should add nomodeset in the end of the kernel line in /boot/grub/grub.conf.I did it but nothing changed.
  Can anybody tell me what should I do?</p>
