I managed to work around it. In the startup of XWin I start a few windows. In one of them I add the font server after a bit of sleep to settle down XWin. Now the XWin does not SIGSEGV any more why so ever.
Here are the scripts I use to start up my X environment Burkhard Startxwin.bat: @echo off SET DISPLAY=127.0.0.1:0.0 REM REM The path in the CYGWIN_ROOT environment variable assignment assume REM that Cygwin is installed in a directory called 'cygwin' in the root REM directory of the current drive. You will only need to modify REM CYGWIN_ROOT if you have installed Cygwin in another directory. For REM example, if you installed Cygwin in \foo\bar\baz\cygwin, you will need REM to change \cygwin to \foo\bar\baz\cygwin. REM REM This batch file will almost always be run from the same drive (and REM directory) as the drive that contains Cygwin/X, therefore you will REM not need to add a drive letter to CYGWIN_ROOT. For example, you do REM not need to change \cygwin to c:\cygwin if you are running this REM batch file from the C drive. REM SET CYGWIN_ROOT=\cygwin SET RUN=%CYGWIN_ROOT%\bin\run -p /usr/bin SET PATH=.;%CYGWIN_ROOT%\bin;%PATH% SET XAPPLRESDIR= SET XCMSDB= SET XKEYSYMDB= SET XNLSPATH= REM Shared Memory support SET CYGWIN=server REM REM Cleanup after last run. REM if not exist %CYGWIN_ROOT%\tmp\.X11-unix\X0 goto CLEANUP-FINISH attrib -s %CYGWIN_ROOT%\tmp\.X11-unix\X0 del %CYGWIN_ROOT%\tmp\.X11-unix\X0 :CLEANUP-FINISH if exist %CYGWIN_ROOT%\tmp\.X11-unix rmdir %CYGWIN_ROOT%\tmp\.X11-unix REM REM The error "Fatal server error: could not open default font 'fixed'" is REM caused by using a DOS mode mount for the mount that the Cygwin/X REM fonts are accessed through. See the Cygwin/X FAQ for more REM information: REM http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-error-font-eof REM if "%OS%" == "Windows_NT" goto OS_NT REM Windows 95/98/Me echo startxwin.bat - Starting on Windows 95/98/Me goto STARTUP :OS_NT REM Windows NT/2000/XP/2003 echo startxwin.bat - Starting on Windows NT/2000/XP/2003 :STARTUP REM Description of XWin-specific options is in XWin(1) manpage.
