[Newbie]There is no window when I start 'X'

[newbie@XFree86.Org (Lee, Myoung Ho)]

I downloaded X420-x.tgz and unziped the files.

And I added follow lines to host.def file to compile the sources to make 'TinyX'.
#define  BuildServersOnly YES
#define KDriveXServer YES
#define TinyXServer YES

Building the sources.
$ make World
$ make install

Run the X
$ X

then the screen is changed to gray color and shows the 'x' mouse curser.
that's all. there is no terminal or window manager.
 
How can I run the window manager?
