We need to know the version of XFree86-xserv.
Xwinrl.log
The log file was called "XWinrl.log" a long time ago for a short period of time... that name has since been changed back to "XWin.log". If your X Server is only storing a log file called XWinrl.log, then I can tell you that you have a quite old version and you really need to run Cygwin's setup.exe again to let it upgrade all of your packages.
