Starting X server on cygwin

[Danielle]

I've installed cygwin with all XFree86 options marked but I can't make it work.

When I type X or startx command lines appears like that:

Danielle@DANI /cygdrive/c/cygwin/usr/X11R6/bin
$ X
bash: X: command not found

Danielle@DANI /cygdrive/c/cygwin/usr/X11R6/bin
$ startx
bash: startx: command not found

Danielle@DANI /cygdrive/c/cygwin/usr/X11R6/bin
$ ./startx
[: and: unknown operand
[: and: unknown operand
export: Settings/Danielle/.Xauthority: bad variable name
xinit: not found

What should I do?

Thanks,
Dani.
