This is not 100% true all the time, but... If you go to your /tmp/.X11-unix directory there will be a file for each server that is running. For instance:
/tmp/.X11-unix ls -a X0 X1 X2 X3 X4 Means you have a VNC server running on ports :0 :1 :2 :3 :4 Again, I have had instances where the VNC server was down, but the X file was still there. But in most cases this will give you the proper info.
