Duplication error upon startx with XWin :0; No terminal with XWin :1

[Angus Veitch]

First of all, thanks to Alexander and Igor for responding to my last 
message.  I'm edging my way forward, but haven't seen the light just 
yet.  I'm still not having much success running startx or xdmcp.  It's 
even possible that some of what I am observing is perfectly healthy, and 
it is my expectations or understanding of the program that are wrong.  
Since I don't know whether all my problems are related, I'll deal with 
startxwin.bat in this email and with startxdmcp.bat in the next one.  
Sorry for all the logs!

I'm running a freshly downloaded cygwin/x, and am trying to connect 
WinXP to a (nearly) freshly installed Linux box running MEPIS.

If I run startxwin.bat with the line "XWin :0 -multiwindow -clipboard 
-silent-dup-error", I successfully load a terminal, but attempting to 
run startx invokes: "Fatal server error: InitOutput - Duplicate 
invocation on display number: 0."  The full XWin.log follows:

I can't find any other xwin processes running (perhaps I don't know what 
to look for), but to keep xwin happy, I instead run startxwin.bat with 
"XWin :1 (...etc)".  The result is that I get no terminal at all  -- the 
cygwin/x window is just a blank grey screen.  The XWin.log follows:

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

So, my question is: Why is the terminal missing when I run startwinx.bat 
with display number :1 rather than :0?

Thanks,
Angus.
