Re: Cygwin/X : display error with latest x-related packages

NOTEWORTHY CHANGES IN 1.17
==

'-nolisten tcp' is now the default, so the server only accepts local 
connections on a unix domain socket. A '-listen' option has been added which 
can be used to restore the previous behaviour.

seeing similar behavior here after upgrading to:
$ uname -a
CYGWIN_NT-6.1-WOW xxx 1.7.35(0.287/5/3) 2015-03-04 12:07 i686 Cygwin

It seems that the server is not opening the tcp/6000 port for remote 
connections.

can you just run startxwin from mintty and report the outcome ?

There were several changes in the default

may be you are hitting one of them.

Cygwin XWin 1.17.1 crash at startup

2015-03-31 Thread Michel Poirier 

Dear Cygwin maintainer

Since last X-Cygwin update several of my X-Win applications are not 
working properly.


Googling "cygwin xorg 1.17 crash" gave many posts reporting probably 
similar issues but I couldn't find a fix for the error. I also looked at 
the Cygwin-FAQ and mailing list without real success.


The issue appeared using a long-time tested DOS script launching xmgrace 
which failed with a message telling "A fatal error has occurred and 
Cygwin/X will now exit." And other XWin programs were not working 
properly. So I tried to make a fresh install of X-Cygwin (32 bits) on 
another computer and went through the procedure explained on page


http://x.cygwin.com/devel/backtrace.html

which produced the debug info attached as "backtrace for X server 
crashing at startup.txt". The X Server crashed when the r command was 
launched and a copy of the Windows error message is provided at "Capture 
of Windows error message.txt". I checked that no other X Server was then 
running and clicked Ok button to finish the procedure.


The content of the file /var/log/xwin/XWin.0.log is listed at the end of 
the first attached file.


I also tried to install the most recent xlaunch program as suggested here

https://www.cygwin.com/ml/cygwin-xfree/2015-02/msg00089.html

but it did not solve the issue.

Sorry for asking something that might be FAQ but as I told I could not 
find a clear answer elsewhere and indeed xlaunch reproduced the error 
consistently.


Thanking you in advance for your assistance, and of course for providing 
this invaluable software that is cygwin.


Regards
