Grass uses display drivers for graphical output. The one that is used for
live screen based output and user interaction is called the XDriver, because
it works through the XWindows system.

We recently made a native Windows equivalent which I referred to (above) as
the "native Xdriver" - it actually doesn't need XWindows on your computer,
but we have not released it publicly yet, except as source code.

There is also a version of the XDriver for use on Windows NT/2000, which
does require XWindows - for example XFree86. The distribution which you
downloaded contains that version.

Yep...

It seems so.

The funny thing about the stuff you provided is that Cygwin thinks you are
user "I have no name!" !!! (Unless you deliberately changed the output for
privacy purposes, or that is your real NT login.) I have never seen that
happen before.

The environment info you provided indicates that you are actually logged in
as "administrator".

It looks like Cygwin installation has gone badly wrong. I would do a
completely clean install, and if you still get that user name when you start
the Cygwin shell, I'm afraid I am at a loss - try the Cygwin mailing list
for that one!

The environment you sent looks OK to me.

"less" is a console text viewer. Say you had a file "hi.txt", you would
type:

less hi.txt

to view the contents.



Good luck.
