Cygwin X11 newbie question

[Matt Lewandowsky]

OK... since there appears to be no FAQ for X11R6.4 for Cygwin anywhere,
I'm going to ask a simple question:

I've downloaded x11r6.4-cygwin-ss-dev.tar.gz, but I can't start X
because I don't have  /usr/X11R6/bin/XGGI. (Or any other "Unixy" X
server, as far as I can tell...) Am I stuck with Exceed? If not, what do
I do? I want to dump my Exceed NT install, but can't if I need it. :(

TIA,

Matt Lewandowsky
