Re: Problem with Cygwin/X from remote Linux

[Chris Carlson <cwcarlsonc@cox.net>]

Hello, Jon.

The version of Fedora I'm running is:
Linux rolf 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 
x86_64 x86_64 x86_64 GNU/Linux

I thought the two logs that you requested were a bit large for this 
e-mail, so I put them on my web site.  You can access them as:
http://beachware.org/Cygwin/glxinfo.cygwin
http://beachware.org/Cygwin/X.log

Believe it or not, I just so happen to have an XWin.0.log from my old, 
old, old version of Cygwin.  It was:

Welcome to the XWin X Server
Vendor: The Cygwin/X Project
Release: 1.15.1.0
OS: CYGWIN_NT-6.1 grover 1.7.30(0.272/5/3) 2014-05-23 10:36 x86_64
OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601](Win64)
Package: version 1.15.1-2 built 2014-05-06

XWin was started with the following command line:

X :0 -multiwindow

Let me know if there's anything else I can provide.
