XWin Won't Run Without -screen Option

["Hon-Chi Ng" <honchi_ng at my-deja dot com>]

Hi

I installed Cygwin 1.3.2 and Cygwin/XFree86 4.1.0 from
ftp://mirrors.rcn.net/pub/sourceware/cygwin/xfree/xc-4-binaries/4.1.0/

I also installed startup-scripts.tgz Release 2 released on Aug 4, 2001.

When I tried to run either startxwin.bat or startxwin.sh, it complained with
"no screen found" error, as shown below.

  $ /usr/X11R6/bin/startxwin.sh
  Agent pid 1124
  
  Fatal server error:
  no screens found
  XIO:  fatal IO error 104 (Connection reset by peer) on X server "127.0.0.1:0.0"
       after 0 requests (0 known processed) with 0 events remaining.
  XIO:  fatal IO error 104 (Connection reset by peer) on X server "127.0.0.1:0.0"
       after 0 requests (0 known processed) with 0 events remaining.
  xterm Xt error: Can't open display: 127.0.0.1:0.0
  xsetroot:  unable to open display '127.0.0.1:0.0'
  twm:  unable to open display "127.0.0.1:0.0"


If I tried running XWin without parameter on both cmd.exe and bash, it
complained with the same "no screen found" error

  $ XWin
  _XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root
  
  Fatal server error:
  no screens found


However, if I supply "-screen 0 1024 768" parameter/argument to XWin command
on either command-line of cmd.exe or bash, or in startxwin.* scripts, the X
server runs and comes out fine.  E.g.

  XWin -screen 0 1024 768


In "Chapter 3. Configuring Cygwin/XFree86" of Cygwin/XFree86 User's Guide at
http://xfree86.cygwin.com/docs/ug/ , it mentions that XWin.exe can be used
without any parameter/argument, which by default, runs in windowed mode with
the largest window that will fit on your Windows desktop, using ...


What have I missed?   Why my XWin won't run without -screen option?

BTW, I read the FAQ at
http://xfree86.cygwin.com/docs/faq/cygwin-xfree-faq.html#AEN261 and searched
the mailing list archives with "no screens" with
http://cygwin.com/cgi-bin/htsearch?config=htdig&restrict=%2Fml%2Fcygwin-xfree%2F&exclude=&method=and&format=builtin-long&sort=time&words=no+screens
, but found nothing mentioned about the "no screens found" error.


FYI, 

  $ /tmp/Xinstall.sh -check
  Checking which OS you're running...
  uname reports 'CYGWIN_NT-5.0' version '1.3.2(0.39/3/2)', architecture 'i686'.
  
  Binary distribution name is 'Cygwin-ix86'


Thanks.

Regards
Hon-Chi
