First off: I have been using Cygwin for about 15 years now, thanks to the maintainers!!!
For a few months now, the only way for me to get Cygwin/X to run was to start a Cygwin terminal ("C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico -"), then run "XWin -multiwindow -clipboard" from there, in the foreground. That has worked for many weeks now. Today, I upgraded from 1.17.1-5 to 1.17.2-1 (I think), and XWin no longer starts as it used to. No X icon appears, XWin exits almost immediately, with return code zero. This is the output: ---- Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 1.17.2.0 OS: CYGWIN_NT-6.1-WOW ************ 2.1.0(0.287/5/3) 2015-07-14 21:26 i686 OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601] (WoW64) Package: version 1.17.2-1 built 2015-07-09 XWin was started with the following command line: Xwin -multiwindow (II) xorg.conf is not supported (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information LoadPreferences: /cygdrive/c/blome/.XWinrc not found LoadPreferences: Loading /etc/X11/system.XWinrc LoadPreferences: Done parsing the configuration file... winDetectSupportedEngines - DirectDraw4 installed, allowing ShadowDDNL winDetectSupportedEngines - Returning, supported engines 00000005 ---- * The machine is not loaded, has plenty of RAM and works fine otherwise. * I used dash -> /usr/bin/rebaseall -v, and feel stupid actually jumping through this particular type of hoop. Still no success. * I rebooted MS Windows. Still no success. * I disabled the firewall. Still no success. * I tried leaving out all command-line args but "-multiwindow". Still no success. * I searched the internet for some of the messages, especially the "xorg.conf is not supported" one. Nothing appropriate. * I read some of the FAQ (searched for "xorg.conf" in it). Nothing appropriate. * I looked at the past two months of mailing list. Nothing appropriate. * I used the Cygwin installer to roll back to 1.17.1.5. Still no success. With Version 1.17.1-5, the package version differed, of course: Package: version 1.17.1-5 built 2015-06-02 and there were additional messages like this, which may have ben caused by the downgrade: Could not load crashreporter dll Other than that, the output was the same. * I also tried the startxwin script, which not surprisingly, gives the above messages plus these: xinit: giving up xinit: unable to connect to X server: Connection refused xinit: server error How can I troubleshoot this further? Rainer PS: My expectation is this: In Cygwin installer, select newest package xorg.server, install, accept suggested set of additional packages to install (dependencies), opt to create shortcuts. Start X11 server via the new shortcut, an X icon appears in the "system tray" (lower right-hand corner). Right-click the X icon, start X11 apps from there. At some point a few years back (at least 2012), this actually worked. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
