Problems starting X server

[Francis Barton]

I have cygwin installed and working from the command line. I have downloaded
and installed all the required X packages using the standard Cygwin
setup.exe.
I am running Windows 98.

I have tried running "startx" "xinit" "startxwin.sh" and "startxwin.bat"
without success. An X window flashes up then disappears.

Here is my error message:
-----------------------------------------------

/usr/X11R6/bin/xinit:  No such file or directory (errno 2):  no server "X"
in PATH

Use the -- option, or make sure that /usr/X11R6/bin is in your path and
that "X" is a program or a link to the right type of server
for your display.  Possible server names include:

    XFree86     XFree86 displays

giving up.
/usr/X11R6/bin/xinit:  Connection refused (errno 111):  unable to connect to
X server
/usr/X11R6/bin/xinit:  No such process (errno 3):  Server error.

---------------------------------------------

/usr/X11R6/bin is in my path, but I'm stuck on what to do next to get X
running.

Also, I am rather confused by the instructions given at
http://xfree86.cygwin.com/docs/ug/setup-cygwin-xfree-installing.html and
related pages, which do not seem to apply to my situation.

I would gratefully receive any advice you can offer.

Many thanks,
Francis Barton.
