I made sure I used that flag (and the spelling you give does match XWin's --help output for the version I am using). Same behavior. I include the XWin.log file below; note that the display starts out 1280x768, so the display changes are to a display of the same size: Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 6.8.1.0-9 Contact: cygwin-xfree@cygwin.com XWin was started with the following command line: /usr/X11R6/bin/X :0 -clipboard -multiplemonitors ddxProcessArgument - Initializing default screens winInitializeDefaultScreens - w 1280 h 768 winInitializeDefaultScreens - Returning _XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root (II) XF86Config is not supported (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information (==) FontPath set to "/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/TTF/,/usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/CID/,/usr/X11R6/lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/" MIT-SHM extension disabled due to lack of kernel support XFree86-Bigfont extension local-client optimization disabled due to lack of shared memory support in the kernel (--) Setting autorepeat to delay=500, rate=31 (--) winConfigKeyboard - Layout: "00000409" (00000409) (--) Using preset keyboard for "English (USA)" (409), type "4" (--) 3 mouse buttons found Could not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing from list! winProcEstablishConnection - Hello winInitClipboard () winProcEstablishConnection - winInitClipboard returned. winClipboardProc - Hello DetectUnicodeSupport - Windows NT/2000/XP winClipboardProc - DISPLAY=127.0.0.1:0.0 winClipboardProc - XOpenDisplay () returned and successfully opened the display. winProcSetSelectionOwner - Clipboard not yet started, aborting. winProcSetSelectionOwner - Clipboard not yet started, aborting. winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winWindowProc - WM_DISPLAYCHANGE - orig bpp: 32, last bpp: 32, new bpp: 32 winWindowProc - WM_DISPLAYCHANGE - new width: 1280 new height: 768 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 1 winWindowProc - WM_DISPLAYCHANGE - orig bpp: 32, last bpp: 32, new bpp: 32 winWindowProc - WM_DISPLAYCHANGE - new width: 1280 new height: 768 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 1 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winWindowProc - WM_DISPLAYCHANGE - orig bpp: 32, last bpp: 32, new bpp: 32 winWindowProc - WM_DISPLAYCHANGE - new width: 1280 new height: 768 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 1 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 2 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 1 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 1 winBltExposedRegionsShadowDDNL - IDirectDrawSurface4_Blt reported that the primary surface was lost, trying to restore, retry: 2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt () failed: 887601c2 winShadowUpdateDDNL - IDirectDrawSurface4_Blt failure message maximum (10) reached.
