I'm afraid that the log doesn't contain enough information for me to identify the cause of the crash. Can you install the xorg-server-debuginfo package and try again? I also have been working on a tool to automate sending better crash information using minidumps. If you would like to try that, download it from [1] (anonymous ftp) and put it into /usr/bin and reproduce your crash again.

I'm not entirely clear if the 'extension “NV-GLX” missing' message is a warning or an error, but according to the internet it seems to be due to having a Nvidia libGL installed on the remote machine, so if all else fails you might look at uninstalling the Nvidia proprietary driver and libGL, and using mesa instead. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
